What Causes the Automatic Transmission Reverse Gear R to Not Respond?

[OPeter]

Automatic transmission reverse gear R not responding is caused by: 1. Fault reasons: If components such as the transmission, oil pump, torque converter, control circuits, solenoid valves, or switches malfunction, the reverse gear may fail to engage. 2. Operational reasons: If the electronic parking brake is not released or the gear shifting is not done properly, the reverse gear may not work. An automatic transmission eliminates the need for the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L.
