Ford Ranger try a nameplate which has been utilized on three distinct design lines of automobiles sold by Ford. Title started in 1958 if the Edsel Ranger had been introduced once the base trim amount of the Edsel design range. From 1965 to 1981, Ranger denoted numerous trim plans of Ford F-Series (and Ford Bronco), providing as a mid- to top-level trim.

When it comes to 1983 design seasons, the Ford Ranger nameplate is applied to a new small pickup, replacing the 1972-1982 Ford Courier in North America. In worldwide markets, Ford began use of the Ranger nameplate in 1998 in place of Courier, along with lightweight trucks named Ranger by 2006.

For 2011, the Ranger ended up being stopped in america and Canada. Similar seasons, Ford commenced production of a mid-size Ford Ranger; marketed globally (apart from the United States and Canada until 2019), production was revived in the us in 2018.

For markets outside the united states, Ford badge engineered the Japanese-built Mazda B-Series once the Courier starting in 1971, renaming they the Ranger in 1998 (apart from Australasia where the Courier nameplate is retained until 2006; incidentally the Courier has also been offered in the united states ahead of the 1983 model seasons). Second-generation Ranger products from 2006 to 2011 were in addition created by Mazda, being rebadged variations for the successor to the B-Series, the very first generation BT-50.

Third-generation models, as created since 2011, had been created and engineered by Ford Australia, with this time the Mazda badged variant becoming the derivative version of the Ford, provided given that second generation BT-50. This third generation normally the basis for Ford Everest SUV and therefore, the Ranger and Everest share some features. The third-generation Ford Ranger, and particularly their most high-priced leading variation (the Ranger "Wildtrak"), has actually greatly enhanced their presence from the European marketplace, creating the Ranger top attempting to sell pickup truck in Europe by 2015.

For 2019 design seasons, the Ranger T6 commences business in united states, with a few additional and internal modifications to adapt to national laws and marketplace demands.
The Mazda B show try a number of pickup trucks first stated in 1961 by Mazda. Because the release for the B series, Mazda have put the engine displacement to determine each model's name; the B1500 had a 1.5 L system together with B2600 had a 2.6 L motor. In Japan, title Mazda Proceed had been used for the compact pickup. More brands useful for this range feature Mazda Bravo (Australian Continent), Mazda Bounty (New Zealand), Mazda Magnum/Thunder/Fighter (Thailand), and Mazda Drifter (Southern Africa).

Mazda's cooperation with Ford resulted in both businesses offering this automobile under different brands; Ford labeled as its version the Ford Courier, and soon after the Ford Ranger. The Mazda B-series and Ford Ranger models offered in united states are developed by Ford, whereas designs marketed somewhere else in exact same badge were engineered by Mazda.

When you look at the 1998 design season, Mazda renewed their B series for worldwide areas. Manufacturing at AutoAlliance Thailand plant began in May 1998. It's the framework rule "UN". This model has also been offered due to the fact Ford Ranger in Europe and Asia so when the Ford Courier in Australian Continent and unique Zealand. Manufacturing in addition began that 12 months at the Ford engine Company Philippines plant. CKD versions are furthermore put together in Southern Africa and Ecuador. In March 2002 a 2892 cc (2.9-liter) form of the naturally aspirated 2.5-liter diesel engine was also created and sold in "general areas" as well as the Gulf says because the B2900.

The vehicle ended up being sold much more than 130 region under a number of names. It had been labeled as the Fighter and Ranger in Southeast Asia---except in Singapore in which it was called the Proceed---the Mazda Bounty and Ford Courier in unique Zealand, the Mazda Bravo in Australia, while the Mazda Drifter in Southern Africa. The B2600/B2200s offered in Venezuela and close by Latin American countries had been put together in Colombia by Compaa Colombiana Automotriz S.A. (CCA). They'd a 2.6-liter inline-four engine, four-wheel-drive design and an entry levels design with a 2.2-liter inline-four with rear-wheel-drive. In 2002, a "Freestyle" model with back suicide doors became available on this platform. Other range had been revised in 2002 and 2004. These models is unrelated on Mazda B-series and Ford Ranger versions in united states.

In Australia, in January 2005, the Courier gotten a 4.0 V6. It absolutely was available in GL (Super taxi and two fold Cab) and XLT (dual taxi best) trims. The B series was launched in September 2005, utilizing the B4000 Bravo DX (Dual taxi only), DX+ (Freestyle and Dual Cab) and SDX (Freestyle and Dual Cab) trims becoming readily available.

There have been two fuel container sizes readily available. When it comes to 2WD Stretch taxi and Dual Cab, the fuel tank size is 63 L. For all 4WD designs (and 2WD Regular taxi), the fuel container dimensions are 70 L.

The Ford Everest or Endeavour try a midsized SUV type of the Ford Ranger that stocks a lot more than 30 percent of the components using donor vehicle design. The concept had been much like the Mazda continue Marvie as well as its Ford Raider twin sold in 1990s based on the earlier generation Mazda B show. It was a four-door SUV, however in comparable manner towards initial Toyota 4Runner of the cargo region having a removable top.

The Everest ended up being sold in Asia, core America while the Bahamas. The Everest was introduced in March 2003; it was built in the AutoAlliance Thailand plant in Rayong, so when CKD kits in Chengalpattu, Asia; and Hai Duong, Vietnam. In India, the Everest was called the Ford Endeavour.

This Everest have its beginnings inside Ford Ranger, that has been designed for the Southeast Asian areas on Rayong plant. Their underpinnings remained truly those of a pickup, while its engine was a Mazda-derived unit utilized for their low-cost, supply efficiency and emissions, which came across the markets' standards. A Hiroshima-based design group developed the Everest/Endeavour to accommodate creating areas. In 2006, the Everest, the Ford Ranger and Mazda B-series pickups were changed with all the newer Mazda BT-50 as well as its derivatives. Although the Mazda versions introduced the latest "BT-50" name, Ford variations carried on underneath the brands "Ranger" for pickups and "Everest" for wagons.

The Everest came with three-row sitting in rear- or four-wheel drive, with either a 2.5-liter diesel or 2.6-liter petrol engine. They rides on a 2,860 mm (112.6 in) wheelbase.

- Safety first
- Wear eye protection, gloves, and steel-toe boots.
- Work on a flat, level surface; chock wheels and engage parking brake.
- Disconnect battery negative terminal before starting.
- Never rely on a jack alone — always use properly rated jack stands and a transmission jack or hoist when supporting the transmission or engine.
- Have a fire extinguisher nearby and clean rags to soak up spills.

- Tools (each with what it is and how to use it)
- Metric socket set (6 mm–24 mm range), 3/8" and 1/2" drive
- Use ratchet for most fasteners; use breaker bar for stuck bolts. Choose socket that fits snugly to avoid rounding heads.
- Torque wrench (click-type, 10–100 ft·lb or larger)
- Use to tighten bolts to factory torque spec. Set to specified value, snug bolt, then apply steady pull until wrench clicks.
- Floor jack (2–3 ton) and jack stands (rated for vehicle weight)
- Lift vehicle with floor jack at manufacturer jacking point, then place jack stands under frame; lower gently onto stands.
- Transmission jack or good floor jack plus wood cradle
- Transmission jack supports heavy transmission during removal/installation. If using floor jack, place wood block to spread load and prevent damage; have helpers guiding weight.
- Engine support bar or hoist (recommended)
- If removing crossmember or dropping engine slightly, use engine support/hoist to prevent engine tilt or damage.
- Breaker bar (18–24") and impact wrench (optional)
- Breaker bar gives leverage for stubborn bolts. Impact wrench speeds removal but be careful reassembly torque control.
- Extensions and universal joints for sockets
- Reach bolts in tight spaces (starter, converter bolts). Use carefully to avoid slippage.
- Pry bars (medium and large)
- Separates transmission from engine; apply gently and evenly, protecting surfaces.
- Screwdrivers and trim tools
- Remove clips and connectors without damage.
- Needle-nose pliers and locking pliers (Vise-Grips)
- Remove cotter pins, hold parts.
- Drift or seal driver set
- Install new seals squarely without damage.
- Hammer (soft-faced recommended)
- Light taps to free stuck parts; avoid heavy blows.
- Plastic/metal scraper and gasket remover
- Clean mating surfaces.
- Drain pan and fluid pump
- Catch and refill transmission fluid; torque converter should be filled per service manual or with transmission fluid pump.
- Wire marker or tape and marker
- Label electrical connectors and linkages for reassembly.
- Flashlight or work light
- Illuminate workspace beneath vehicle.
- Shop manual or manufacturer torque/spec sheet (paper or printed)
- Use for bolt torque values and model-specific steps.

- Special or extra tools you may need and why
- Transmission jack (highly recommended)
- Transmission is heavy and awkward; a transmission jack makes removal/installation safe and accurate.
- Torque converter holding tool (or long pry bar and care)
- Holds flexplate or converter while loosening/tightening bolts; prevents rotation.
- Pilot bearing/bushing puller/installer (if applicable)
- If pilot bushing needs replacement, puller removes it cleanly; not always required.
- Rear main seal installer (if replacing rear seal)
- Ensures correct seating of seal without distorting it.
- Engine support/hoist
- Prevents engine from shifting if mounts are loosened.
- Impact wrench (optional for removal only)
- Speeds bolt removal; do not use for final torque.

- Parts you will likely need to replace (and why)
- New torque converter (required if current converter is failing or damaged)
- Reason: worn clutch surfaces, internal bearing/failure, shudder or contamination. If replacing only converter, ensure replacement matches engine/transmission model and is correctly balanced.
- New torque converter bolts (recommended)
- Reason: bolts stretch and can fail; cheap insurance and many are single-use.
- Flexplate (inspect; replace if cracked or warped)
- Reason: cracked or worn bolt holes will cause vibration and possible bolt failure.
- Rear main seal and transmission input seal (recommended inspection/replacement)
- Reason: seals often disturbed during removal; replacing prevents leaks.
- Transmission fluid and filter (if applicable)
- Reason: old fluid contaminates new converter; refill with correct fluid after reassembly. Replace filter if the transmission has a serviceable one.
- Pilot bushing/bearing (if damaged)
- Reason: supports converter pilot; worn part causes misalignment and wear.
- Bolts/nuts (engine-transmission and crossmember fasteners) if corroded or damaged
- Reason: hardware may be seized or damaged during removal.

- Preparatory steps
- Gather all tools, replacement parts, and shop manual for torque specs and sequence.
- Raise vehicle and support with jack stands; remove front wheels if needed for access.
- Drain transmission fluid into drain pan (optionally leave some in converter if transmission is not separated far).
- Label and disconnect electrical connectors, speedometer/gear selector linkages, and neutral safety switch.
- Remove driveshaft(s) or CV axles (for 2WD, remove driveshaft; for 4x4, follow transfer case procedure).
- Remove exhaust components obstructing transmission removal (downpipe, mid-pipe) enough to slide transmission back.
- Remove starter motor to access bellhousing bolts.

- Transmission removal and exposing torque converter
- Support transmission with transmission jack and/or floor jack with wood cradle under pan.
- Remove transmission crossmember and mount(s) while supporting transmission.
- Remove bellhousing bolts that secure transmission to engine. Keep track of bolt locations.
- Slide transmission rearward slowly (use jack), just far enough to access torque converter bolts through inspection cover or starter hole. Do not fully separate transmission while torque converter bolts are still installed — converter will fall off rear of engine or damage pump.
- Once converter bolts are visible, rotate engine manually (via crank or by moving converter) so holes align; remove converter-to-flexplate bolts (support converter from rear so it does not drop).
- Carefully separate transmission from engine the remainder of the way and lower transmission with the jack, keeping torque converter attached to engine or transmission depending on how you proceed.

- Removing the old torque converter (if removing from engine)
- With transmission lowered and supported, pull converter away from engine flexplate.
- Inspect flexplate bolt faces and converter pilot/hub for wear.
- If converter will be discarded, drain remaining fluid into pan.

- Installing new torque converter
- Pre-fill torque converter with recommended amount of transmission fluid if manufacturer requires; rotate and fill so fluid moves into stator and pump area to reduce dry start.
- Align new torque converter pilot to engine crank pilot carefully and slide it fully onto the pump drive of the transmission (you should feel multiple distinct engagement points as it seats; typically three “clicks” as it engages pump and stator shaft). Ensure converter is fully seated flush against transmission pump face — incomplete seating will cause pump seal damage on startup.
- Rotate converter so bolt holes align with flexplate; thread bolts by hand to avoid cross-threading. Use new bolts if possible.
- Tighten bolts in a criss-cross pattern to factory torque spec using torque wrench.

- Reinstall transmission
- Lift and guide transmission into place using transmission jack; ensure torque converter splines and pump align. Transmission should contact engine with little gap if converter seated.
- Reinstall bellhousing bolts loosely, then tighten to manufacturer torque sequence and specs.
- Reinstall transmission mount(s), crossmember, starter, driveshaft/axles, exhaust components, and any removed parts.
- Reconnect electrical connectors, linkages, and lines.
- Refill transmission to proper level with recommended ATF type (check owner's/service manual). With engine running and transmission in park/neutral, check fluid level and add as required.

- Testing and final checks
- With vehicle on stands or safely lifted, start engine and run at idle; check for leaks around torque converter and seals.
- Cycle through gears to warm fluid; recheck fluid level and top to proper level per manual.
- Road test gently, then re-check for leaks and noises. Inspect flexplate runout/vibration after initial test.

- Tips and cautions
- Never start the engine if the torque converter is not fully seated and properly bolted — this will destroy the transmission pump.
- Keep fasteners organized and note lengths/locations; many are not interchangeable.
- Replace any damaged or heavily corroded bolts rather than reusing.
- If unsure about seating or balance, get the converter installed or inspected by a professional — incorrect installation risks catastrophic transmission damage.
- Use factory torque specs from the service manual for all bolts; do not guess torque values.

- Common mistakes and how to avoid them
- Incomplete converter seating — ensure full engagement (feel the clicks) and ensure transmission and converter bolt holes align before bolting.
- Relying on floor jack only — always use proper support (transmission jack + jack stands).
- Reusing stretched/old bolts — replace torque converter and critical fasteners.
- Not pre-filling converter when required — leads to dry pump start and internal damage.

- Quick parts checklist to buy before starting
- Correct model torque converter for your Ford Courier/Ranger engine/transmission combination
- Torque converter bolts (new set)
- Transmission fluid (correct spec and quantity)
- Transmission filter and gasket (if applicable)
- Rear main seal and input seal (optional but recommended)
- Flexplate (or have a known-good one inspected)
- Misc hardware as needed

- Final note
- Follow the vehicle’s factory service manual for model-year-specific steps, torque specs, and safety instructions. If you lack a transmission jack or are uncomfortable lifting and aligning heavy components, hire a shop — the risk to the transmission and personal safety is high without proper equipment.

The accelerator linkage on a Ford Courier-Ranger connects the accelerator pedal to the throttle body, allowing the driver to control engine power by regulating air intake. When this linkage malfunctions, it can lead to poor throttle response, stalling, or inability to accelerate.

### Theory Behind the Repair:

1. **Understanding the Components**:
- **Accelerator Pedal**: When pressed, it initiates movement through the linkage.
- **Linkage System**: A series of rods, cables, and pivots that translate the pedal movement to the throttle body.
- **Throttle Body**: Controls airflow into the engine based on the position of the linkage.

2. **Identifying the Fault**:
- **Symptoms of Failure**: Poor acceleration, unresponsive throttle, or stalling can indicate a broken or misaligned linkage.
- **Visual Inspection**: Check for damage, wear, or disconnection in the linkage components.

3. **Repair Process**:
- **Disassembly**: Remove any covers or components obstructing access to the accelerator linkage.
- **Inspection**: Examine each component for wear or damage. Look for frayed cables, bent rods, or broken connections.
- **Replacement**: If a component is damaged, replace it with a new part to restore functionality. Ensure that the new part matches the specifications for a proper fit.
- **Adjustment**: Adjust the linkage to ensure proper travel and response. This step is crucial as it affects the throttle opening in relation to pedal movement.
- **Reassembly**: Once repairs are made, reassemble any components removed during the process.

4. **Testing the Repair**:
- **Functionality Check**: After reassembly, start the engine and test the accelerator pedal’s response. Ensure the throttle opens fully and smoothly with pedal input.
- **Final Adjustments**: If necessary, make additional adjustments to the linkage for optimal performance.

### How the Repair Fixes the Fault:
- **Restores Connection**: Replacing or repairing damaged components reconnects the pedal to the throttle body, allowing for effective communication between the driver’s input and engine response.
- **Ensures Proper Operation**: Adjustments ensure that the throttle opens correctly with pedal movement, enhancing responsiveness and preventing stalling.
- **Prevents Future Issues**: Addressing wear and damage can prevent future failures, ensuring reliable vehicle operation.

By understanding these concepts, you can appreciate how each step in the repair process contributes to restoring the functionality of the accelerator linkage, ultimately ensuring the vehicle operates safely and efficiently.

Below is a concise, ordered workshop-level procedure for replacing the automatic transmission front (pressure) pump on a Ford Courier / Ranger family vehicle, with the underlying hydraulic/mechanical theory at each stage and an explanation of how the repair cures the fault. I state generic actions because specific fastener locations, torque values, and pressure specs vary by year/model — always apply factory specs for those numbers.

Summary of pump function and failure theory (brief)
- Function: the front pump draws ATF from the pan/strainer and converts low-pressure flow into high-pressure flow for the hydraulic control circuits (line pressure, clutch/servo apply, valve body metering). Most automatic transmissions use a gear/gerotor type pump driven by the input shaft/torque converter housing. The pump must maintain volumetric efficiency (seal clearances, good rotor/gear condition) to produce required line pressure.
- Typical failure modes: worn rotor/bores or seals, cavitation from low fluid/air ingress, scored bores from contamination, debris/jammed clutch check balls, or damaged drive hubs. Resulting symptoms -> low line pressure, slipping, delayed or harsh shifts, failure to engage, overheating, poor modulation, and internal leakage.
- How replacement fixes it: a new pump restores correct internal clearances and sealing surfaces so flow-to-displacement ratio returns to design values, restoring line pressure and hydraulic force to the clutches/servos, eliminating internal leakage that caused slipping and wrong shift behavior.

Ordered workshop procedure with theory at each step

1) Preparation and safety
- Action: Park on level surface, chock wheels, disconnect negative battery terminal, lift and support vehicle securely on stands, drain transmission fluid.
- Theory: Removing pressure plus battery prevents electric/hydraulic activation. Draining reduces mess and fluid loss when disconnecting lines. Ensure safety — transmission weight is large.

2) Confirm fault and baseline tests (before teardown)
- Action: With transmission still in vehicle, check basic diagnostics: measure line/line-pressure with a gauge at specified test port, record pressure at idle/in drive/at higher RPM; note shift timing and slipping. Scan for codes.
- Theory: Documenting pressure and behavior confirms pump is the root cause (low line pressure) vs. valve body or electronic control. Pump failures show low system pressure across ranges and generally hydraulic symptoms rather than purely electrical faults.

3) Lower driveline components & access transmission
- Action: Remove driveline (propeller shaft), starter, exhaust sections as needed, and any wiring or cooling lines in the way. Support the transmission with a jack and remove crossmember(s) and mount(s) so the transmission can be lowered if required.
- Theory: The front pump sits at the transmission’s nose and may require separating torque converter from flywheel and dropping transmission or splitting case. Access is mechanical — clearances, torque converter and input shaft must be accessible.

4) Remove transmission (if required)
- Action: Unbolt torque converter from flexplate (or remove bolts after rotating engine to access) while supporting it; remove bellhousing bolts; lower transmission out of vehicle.
- Theory: Many replacements require transmission removal because the pump is driven by the input/front of the case and is sealed in the case. Removing the transmission gives controlled access to split the case or remove the pump assembly.

5) Disassemble transmission front end to access pump
- Action: Clean exterior to avoid contamination. Remove oil pan, valve body (note bolt locations and plungers/balls), valve body separator plate, and internal components as needed to access the pump and front cover. On some models, remove the front pump housing/cover, torque converter pump drive hub, and input shaft.
- Theory: The pump is integral with the front housing and often driven by the converter hub/input shaft. Valve body removal is necessary to reach torque converter housing and pump assembly. Cleanliness is critical: contamination damages the new pump.

6) Remove the old pump and inspect mating components
- Action: Unbolt pump housing/front cover; press or slide out pump rotor/gerotor assembly. Inspect mating surfaces, drive hub, input shaft splines, pump bore for scoring, and the front case for damage. Check torque converter hub, front seal seat, and stator/relief valves.
- Theory: Pump failure frequently produces debris (metal particles). Inspecting the drive hub and input shaft ensures you don’t install a new pump onto a damaged drive that will quickly fail. Replace any damaged components (drive hub, seal, clutch parts) because they affect pump drive and sealing.

7) Clean, measure, and decide repair vs full rebuild
- Action: Thoroughly clean all internal passages, remove debris from pan and magnet, and replace filter/strainer. Measure pump bores, rotor clearances and check for scoring. If case bores are damaged beyond spec, either machine and sleeve or replace case/transmission.
- Theory: Pump performance depends on precise clearances. Cleaning eliminates abrasive particles that would ruin a new pump; measuring ensures the environment will accept a new pump. If the case bore that supports the pump is worn, a new pump alone will still leak and not restore pressure.

8) Install new pump assembly and seals
- Action: Fit new pump (or rebuilt unit) into the housing, replace front seal, O-rings, dowels, and cover gasket. Ensure correct orientation and mating surfaces are clean and lubricated with ATF. Torque all fasteners to spec and replace any paper gaskets or seals.
- Theory: A new pump re-establishes the volumetric displacement per revolution. Replacing seals eliminates the internal leakage paths that reduce system pressure. Proper torque and alignment prevent distortion that would change clearances.

9) Reassemble internal components and valve body
- Action: Reinstall converter (after checking for internal contamination), input hub, valve body/separator plate with correct clearances and any shims, and pan with new filter and gasket. Reinstall transmission to engine if removed; torque bellhousing and converter bolts to spec.
- Theory: Valve body components and check balls must be correctly placed so the new pump’s pressure is correctly routed. Any leftover contamination can compromise pump or clutch systems.

10) Reconnect lines, fill with correct fluid, and flush cooler lines
- Action: Reconnect cooling lines and wiring, reattach mounts and crossmember, install prop shaft. Refill with the specified ATF to about the mid-level; after initial start and warm-up, check fluid level per factory procedure (some require running at temp with selector positions).
- Theory: Correct fluid type and level are essential for pump lubrication and hydraulic characteristics. Flushing cooler lines removes old debris that could re-contaminate pump.

11) Start-up checks and pressure verification
- Action: With transmission warm and parking brake on, measure line pressure at the specified test port at idle and at specified RPMs and gears. Confirm pressures meet factory specs. Cycle through gears and check for leaks and proper engagement without slip.
- Theory: The new pump must generate the required steady and regulated line pressure. Pressure checks verify the repair solved low-pressure condition and that hydraulic circuits operate. Also monitor for noises (cavitation, whining), which indicate residual air or cavitation.

12) Road test and final validation
- Action: Road test the vehicle through full shifts under light and moderate load. Confirm no slipping, no harsh or delayed shifts, no overheating, and no error codes. Re-check fluid level and inspect for leaks after cool-down.
- Theory: Under load, the pump must sustain pressure and enable clutch packs/servos to apply and hold. A successful road test proves the volumetric output and mechanical drive are correct.

Why this repair fixes the fault (concise)
- Root cause: A worn or damaged pump cannot produce the required hydraulic pressure because internal leakage (worn rotors/bores/seals) lowers volumetric efficiency and permits flow back to the pan instead of into the control circuits.
- Replacement effect: A new pump reestablishes design clearances and sealing faces so each pump revolution forces the correct volume of fluid into the pressure circuits. This restores line pressure, allowing proper clutch/servo engagement and shift modulation, removing symptoms such as slipping, failed engagement, and overheating caused by slippage and low pressure.
- Note on contamination and ancillary parts: If the pump failed due to debris, remaining contamination, a damaged torque converter drive hub, or worn case bore will quickly re-damage a new pump. That’s why inspection, cleaning, new filter, and replacing any damaged mating parts are essential to make the repair permanent.

Quick troubleshooting mapping (symptom → likely pump-related cause)
- Low/no drive, engine revs high on selection → severe low line pressure or pump seizure / torque converter coupling failure.
- Slipping under load & overheating → reduced-volumetric-efficiency pump (internal leakage).
- Whine at all RPMs, cavitation bubbles in pan → pump cavitation or air ingestion (low fluid, bad pick-up, torn seal).
- Intermittent loss of pressure / delayed shifts → partial pump wear, check ball/valve contamination, or leaking seal.

Essential cautions and best-practices
- Maintain absolute cleanliness when opening the hydraulic system.
- Replace filter/strainer and pan gasket; flush cooler lines if contamination suspected.
- Inspect/replace torque converter if metal contamination or damaged hub is present.
- Use correct ATF type and factory pressure specs for verification.
- If bore or case is worn, you must repair or replace the case/transmission — fitting a new pump into a worn bore won’t reliably restore pressure.

End.
