What causes the loud 'bang' sound when reversing in an automatic transmission car?
1 Answers
Hearing abnormal noises when reversing in an automatic transmission car is caused by gear shift shock. Here are possible reasons and solutions for gear shift shock: 1. Faulty clutch plates inside the transmission: Solution: If the transmission fluid smells burnt, it indicates the clutch plates inside the transmission are burned out. The transmission needs repair. 2. Transmission system malfunction: Solution: If the transmission system shows error codes. Repair according to the error codes (be sure to go to a professional auto repair shop for repairs). 3. Faulty oil circuit control board: Solution: If the internal valve body of the oil circuit control board is burned out. Go to a repair shop for repairs.
