What are the reasons for an automatic transmission car not moving when starting?
1 Answers
Automatic transmission car not moving when starting reasons are as follows: 1. Car does not move when in gear: The car does not move when in gear, which is a comprehensive functional failure involving the clutch, transmission, and drive axle. When diagnosing, the fault location should be determined first, and the condition of the two wheels can be checked first. The order of diagnosis is generally from the drive wheels forward through the rear axle to the drive shaft and then to the transmission, and finally to the clutch. If the drive shaft rotates but the car does not move forward, the fault is in the rear axle. 2. Car does not move when starting in a certain gear, drive shaft does not rotate: If the car does not move when starting in a certain gear and the drive shaft does not rotate, it indicates that the fault is in the transmission. Remove the transmission cover and check whether the transmission shift fork is broken or whether the guide block fixing screws are loose. If the above checks are normal, perform a gear engagement test. If the second shaft does not rotate in a certain gear, it means the half-round key of that gear is cut off.
