New 22PIN Transmission Wire Harness DEAD340301 Fit Dongfeng Fengxing A6F5 6

This brand-new 22PIN internal valve body wire harness matches A6F5 6-speed automatic transmission, exclusive OEM part number DEAD340301, specially designed for Dongfeng Fengxing vehicles equipped with original A6F5 6AT gearbox.

The transmission internal wiring harness acts as the signal transmission bridge between TCU and hydraulic valve body. Aging broken wires, cracked insulation, corroded pins will lead to gear shifting failure, gear jerk, fault code pop-up, no reverse gear and power interruption. Our wiring harness adopts high-temperature resistant automobile-grade wire core, fully sealed waterproof plastic connector, each finished harness passes full circuit continuity & insulation test before shipment, perfectly match original plug pin definition for direct plug-and-play replacement without modification.

Warm Reminder: This 22PIN wire harness only fits Dongfeng Fengxing models factory-equipped with A6F5 6AT gearbox, cannot interchange with other series CVT/DCT/AT gearbox wiring harness. Send your complete 17-digit VIN code for free pre-order matching verification to avoid mismatching and costly cross-border return shipping fees.

1. Automotive-Grade High-Temp Wire Raw Material: Adopt oil-resistant, high-temperature, anti-aging copper wire core, adapt to long-term high heat inside gearbox.
2. Standard OEM Pin Layout & Sealed Connector: Strictly copy original 22PIN pin assignment, integrated waterproof rubber sealing ring to prevent CVT oil corrosion and short circuit.
3. Fixed Torque Crimping Terminal Process: Automatic CNC crimping machine ensures stable terminal connection, avoid open circuit caused by loose contact.
4. Full Circuit Continuity & Insulation Test: Every harness undergoes full-channel conduction detection and high-voltage insulation test to eliminate short-circuit or open-circuit defective products.
5. Anti-Oil Protective Sleeve & Independent Shockproof Packing: Each wire harness wrapped with wear-resistant corrugated tube, packed into independent carton with foam buffer, blank neutral packaging or custom printed OEM labels supported for bulk orders.

22PIN connector layout, wire length, plug size fully consistent with factory original DEAD340301 harness, directly plug into A6F5 valve body and TCU without cutting or rewiring during repair.

All wires and rubber seals resist long-term soaking of high-temperature AT fluid, solve common after-sale issues like wire hardening, cracking, pin corrosion of cheap inferior harnesses.

We test conduction and insulation for every single harness before delivery, fully avoid shipment of defective open/short-circuit goods, greatly reduce your downstream repair shop complaint risks.

1 piece sample order is acceptable, tiered volume discount for bulk orders to lower your stocking capital pressure. Standard blank neutral cartons without factory logos; customized printed OEM number and brand labels available for large batches.

We have dedicated engineers specializing in Dongfeng A6F5 6AT transmission parts, providing remote one-on-one video guidance for harness plug matching and shifting fault troubleshooting for your overseas repair stores.

1. Lift the whole vehicle, drain all ATF fluid, disassemble A6F5 gearbox oil pan and take down internal valve body assembly.
2. Unplug the aged original wire harness connector from valve body and TCU, clean oil sludge and corrosion residue inside connector socket.
3. Install our new DEAD340301 22PIN wiring harness, align each pin plug tightly, fix wire layout with original plastic buckle to avoid friction wear.
4. Replace new transmission filter and full sealing gasket kit, refill matched ATF fluid up to factory standard capacity.
5. Connect diagnostic scanner to clear TCU fault memory codes, conduct road test to confirm smooth shifting without jerk or fault light alarm.
