New 8F35 Transmission Valve Body Assembly for Ford Mondeo 8 Speed Automatic Gearbox Hydraulic Control Mechatronic Unit

This 8F35 integrated mechatronic valve body assembly matches Ford Mondeo equipped with 8F35 8-speed automatic transmission, OEM No. KTJM5P7A100-BA / 2305681.

The mechatronic unit is the core hydraulic & electronic control center of the gearbox. Aging solenoids, internal sludge accumulation and plunger wear commonly lead to shift shock, slipping, delayed gear engagement, fault codes and transmission limp mode.

Our remanufactured valve body undergoes complete disassembly, deep cleaning, renewal of all vulnerable components and full hydraulic bench calibration. Direct plug-and-play replacement for auto repair workshops.

1. Housing Screening: All recovered aluminum housings go through penetration crack inspection; cracked, deformed housings are eliminated directly.
2. Full Disassembly & Deep Cleaning: Disassemble all internal components, remove carbon sludge and metal debris inside every oil channel by high-pressure circulation cleaning.
3. Vulnerable Parts Renewal: Replace solenoids, sealing rings, plungers and filter screens with brand-new matched spare parts.
4. Standardized Assembly: Assemble all parts following unified torque standards to prevent assembly clearance deviation.
5. Multi-condition Hydraulic Bench Test: Simulate idle, acceleration, shifting and heavy load working conditions to calibrate hydraulic pressure and shift logic.
6. Electrical Circuit Inspection: Test solenoid signal transmission to eliminate short circuit or open circuit risks.
7. Export Shockproof Packing: Anti-rust film + customized EPE foam + neutral carton to protect precision components during long sea and air transportation.

• Complete Integrated Mechatronic Assembly

Hydraulic valve body and electronic solenoid module pre-assembled as one unit. No extra matching work required during installation.

• 1:1 OEM Structure, Plug & Play

Outline, oil port layout and wiring connector position fully consistent with original OEM parts. No modification needed, greatly shorten overhaul time.

• 100% Bench Test Before Shipment

Every finished valve body passes repeated cycle pressure testing to stabilize shift hydraulic pressure, suitable for high-temperature and bumpy road conditions in global markets. Low after-sales failure rate.

• Flexible Wholesale Policy

1 unit minimum trial order. Tiered discount for bulk purchases. Neutral blank carton and custom label printing available. Negotiable warranty terms for long-term cooperative distributors.

1. Lift vehicle, fully drain original ATF fluid, remove transmission oil pan and internal filter.
2. Disconnect the mechatronic wiring harness plug, remove fixing bolts and take out the whole valve body assembly.
3. Thoroughly clean the transmission mounting surface, wipe residual oil sludge and old sealant.
4. Install new 8F35 valve body, tighten bolts following factory torque specification and reconnect wiring plugs.
5. Install new oil pan gasket, refill specified Ford ATF fluid, clear ECU fault codes and perform road test to verify smooth shifting without alarm.
