Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Fluid Level Check

Remove the transmission dipstick (if equipped).
Check the fluid level; it should be within the designated range.
If low, add the recommended transmission fluid type (refer to the owner's manual).

3. Inspect Transmission Linkage

Locate the transmission linkage connected to the shifter.
Inspect for any loose connections or damage.
Tighten or replace any worn components as necessary.

4. Transmission Control Module (TCM) Check

Reconnect the battery and power on the vehicle.
Access the TCM using an OBD-II scanner.
Check for firmware updates and reprogram if necessary.
Clear any stored DTCs and test the shift into reverse again.

5. Test Drive

After repairs, take the vehicle for a test drive.
Shift through all gears, including reverse, to confirm proper operation.
