What is the reason for the car not engaging in reverse gear?

[SanCorey]

If the vehicle is equipped with an automatic transmission, the reason for the car not engaging in reverse gear could be a malfunction in the transmission's internal control module, among other issues. If it's a manual transmission, the cause might be faults in the clutch system's release bearing, friction disc, or pressure plate. Below is some relevant information about gear shifting: 1. Introduction: Gear shifting (changing gears) refers to the transmission, which is used to alter the torque and speed of the engine crankshaft to meet the varying requirements of traction and speed for the driving wheels under different driving conditions such as starting, accelerating, driving, and overcoming various road obstacles. 2. Function: It allows the car to drive at a very low and stable speed, which would be difficult to achieve solely by the internal combustion engine's minimum stable speed; the transmission's reverse gear enables the car to move backward; its neutral gear allows the engine to be separated from the drivetrain for extended periods during engine start-up, parking, and coasting.
