What Are the Common Faults After a Transmission is Submerged in Water?
1 Answers
Common faults after a transmission is submerged in water include automatic transmission fluid deterioration, clutch damage, transmission slipping, and transmission oil leakage. Automatic Transmission Fluid Deterioration: Water entering the automatic transmission directly causes the transmission fluid to deteriorate and oxidize, reducing its friction coefficient. As a result, the vehicle components lack sufficient friction, leading to symptoms such as jerking, impact, and slipping in the automatic transmission. Clutch Damage: Water entering the automatic transmission not only damages the transmission fluid but is also highly detrimental to the clutch plates. If the clutch plates are submerged in water and cannot be repaired, replacement is the only option, which increases the corresponding repair costs. Transmission Slipping: During driving, if the engine revs up but the vehicle speed does not increase, accompanied by a feeling of overall weakness, this is often caused by burnt clutch plates. Water entering the transmission due to external factors, such as coolant mixing with oil or water entering through the transmission vent cap, can cause abnormal transmission operation. Transmission Oil Leakage: Oil seeping from the transmission housing or oil pan can be caused by aging seals leading to poor sealing or manufacturing defects resulting in pinholes in the housing.
