What Causes a Transmission Failure Where Reverse Gear Doesn't Work?

[LeMarcus]

Reasons for transmission failure where reverse gear doesn't work: There may be a fault in the power electronic control system, possibly due to a faulty sensor connection circuit in the transmission, lack of automatic transmission fluid, overheating of the automatic transmission, or failure to increase speed caused by a slipping one-way clutch, among others. Functions of the transmission: 1. Changing the transmission ratio: To meet the traction needs under different driving conditions, allowing the engine to operate under optimal conditions and meet possible speed requirements. 2. Enabling reverse driving: To meet the need for the vehicle to move backward. The engine crankshaft generally only rotates in one direction, but vehicles sometimes need to move in reverse, hence the reverse gear in the transmission is used to achieve this. 3. Interrupting power transmission: To stop power transmission to the drive wheels when the engine starts, idles, during gear shifts, or when parking is required for power output. 4. Enabling neutral gear: When the clutch is engaged, the transmission can stop power output. For example, this allows the driver to release the clutch pedal and leave the driver's seat without turning off the engine.
