What are the common problems with the Fengdu A33 transmission?
1 Answers
Common problems with the Fengdu A33 transmission include: 1. Oil leakage: Oil seeps from the transmission casing or oil pan, which can be caused by aging seals leading to poor sealing or manufacturing defects resulting in sand holes in the casing. 2. Engine stalling when shifting into D or R: This issue may be due to a damaged lock-up solenoid valve or a stuck lock-up control valve. Symptoms include the vehicle not moving after shifting into D or R and releasing the brake, or the car moving a short distance when cold but not when hot. This is often caused by damage to the input shaft or reverse clutch, or failure of the D/R brake. It could also result from severe transmission oil leakage leading to low oil levels, or a loose linkage or cable between the shift lever and the manual valve lever, keeping the manual valve in neutral or park. 3. Transmission slipping, poor acceleration, or water ingress: During driving, the engine may rev without a corresponding increase in speed, indicating a lack of power, often due to burnt clutch plates. Water entering the transmission, possibly from a leaking radiator or through the transmission vent cap, can cause abnormal operation. 4. Unusual odors from the transmission: The transmission relies on hydraulic fluid, and excessively high temperatures can cause burning, emitting odors that indicate malfunctioning components. 5. High engine RPM during driving: Consistently high RPMs during steady driving usually point to failure of the transmission's high gear or the torque converter's lock-up clutch, necessitating immediate transmission repair.
