What are the common faults in transmission repair?
2 Answers
Common faults in transmission repair are as follows: Transmission oil leakage: Oil seeps out from the transmission housing or oil pan, which can be caused by aging seals leading to poor sealing, or poor manufacturing processes resulting in sand holes in the housing. Clogged transmission oil filter, severe oil leakage, or damaged oil pump: During driving, the vehicle may experience gear shift impacts or jerks, which are common symptoms of automatic transmission faults. This may be caused by dirty transmission oil leading to valve body sticking. Transmission slipping, lack of acceleration, or water ingress in the transmission: While driving, the engine may rev without a corresponding increase in vehicle speed, making the car feel sluggish. This is often caused by burnt clutch plates. Water entering the transmission due to external factors can cause abnormal operation, possibly due to oil mixing in the radiator or water entering through the transmission vent cap.
Having driven for over 20 years, I've seen plenty of common transmission issues. Gearshift jerking and delays are most frequent, possibly due to clutch slippage or dirty fluid; metallic rattling noises usually indicate gear wear or torque converter failure; oil leaks are also common, often caused by seal aging leading to low fluid levels and overheating damage. Once my car got stuck in gear on the highway - terrifying experience that turned out to be a failed sensor. Automatic transmission electronics are delicate, while manual synchro rings wear easily. Recommend changing fluid every 50-60k km and keeping it clean; avoid aggressive driving and heavy towing. Repair any malfunction immediately - safety first, don't penny-pinch on critical components. Regular maintenance saves hassle long-term.
