Causes and maintenance methods of not engaging reverse gear;
1. The gearbox shifts gears by changing the gear engagement ratio. If the automatic transmission vehicle can't shift gears, it may be that the gear controlling the reverse gear in the gearbox is damaged, so just change the gear controlling the reverse gear in the gearbox.
2. The clutch bearing falls off, the clutch is insufficiently lubricated, and the clutch is seriously worn, which will lead to the failure to hang the reverse gear. Cars mainly go to 4s shops or repair shops in time for professional inspection and maintenance.
Causes and solutions of automatic transmission not being engaged;
1, the vehicle battery is in a state of power loss, which will lead to the inability to shift gears. The owner can check whether there is a light on the dashboard and press the horn to make it sound as usual. If there is no light on the dashboard and the horn doesn't ring as usual, it means that the battery is in a power-off state. It can be solved by charging and repairing the battery;
2. The gear lock of the vehicle is locked. Maybe the owner forgot to unlock the lock, or maybe he accidentally touched the switch of the gear lock. There will be a shift lock button next to the gear lever of the vehicle. Just press it to open the shift lock.
It is easy to get stuck in cold gear in winter, but the car can get stuck in gear after warming up. This is because the fluidity of engine oil and gearbox oil is very slow when the car is cold, and the low temperature in winter makes its fluidity slower and worse. When the viscosity of the transmission oil becomes larger, the shift resistance of the transmission will become larger, and the viscosity of the transmission oil will not work. If the car is warmed up, the transmission oil and engine oil will rise to a certain temperature, and the liquidity will recover well and they can work normally.
