What are the reasons for the car not moving in reverse?

The reasons for the car not moving in reverse are as follows: 1. If the car does not move when in gear, it is a functional comprehensive fault involving the clutch, transmission, and drive axle. When diagnosing, the fault location should be determined first. You can start by checking the condition of the two wheels. Lift the rear axle and rotate one rear wheel. If the other rear wheel rotates in the opposite direction but the drive shaft does not follow, it indicates that all the rivets of the driven bevel gear are sheared off. If the other rear wheel does not rotate, the half shaft should be disassembled and inspected for breakage. 2. If the car does not move when starting in gear and the drive shaft does not rotate, the fault lies in the transmission. Remove the transmission cover and inspect whether the transmission shift fork is broken or whether the guide block fixing screws are loose. 3. If the drive shaft does not rotate in any gear position, the fault lies in the clutch. Check whether the clutch is severely slipping, whether all the rivets of the driven disc spline hub and steel plate are sheared off, or whether the steel plate is fractured.
I've encountered the trouble of the car not moving in reverse before. When driving a manual transmission car, the wheels wouldn't move after engaging reverse gear, which was really frustrating. The most likely cause is clutch slippage. When the clutch plates of an old car are severely worn, there might be no response when shifting gears, and new parts need to be replaced immediately. For automatic transmissions, the problem is more complex. Deteriorated or low transmission fluid can affect the operation of the reverse gear, and excessive sludge can lead to poor lubrication and sticking. Another issue could be brake system failure, such as brake disc adhesion after prolonged parking or caliper seizure, creating significant resistance when reversing. Don't overlook electronic issues either; a faulty reverse switch or sensor can cause abnormal gear signals. For safety, if the car doesn't move in reverse, don't force it. Engage the handbrake, get out, and check if the brakes are released. Remember to perform regular maintenance and check the transmission fluid. I've since developed a habit of checking the fluid level every six months.
