Solution

1. Preparation

Tools Required: OBD-II scanner, basic socket set, multimeter, transmission fluid.
Safely park the vehicle on a flat surface and engage the parking brake.
Disconnect the vehicle's 12V battery to prevent electrical shorts.

2. Inspect Gear Selector

Remove the gear selector cover using a trim removal tool.
Check for any debris or objects that may be obstructing the gear shift.
Ensure that the gear shift linkage is properly connected and functioning smoothly.

3. Check Transmission Fluid

Locate the transmission fluid dipstick or access port.
Pull the dipstick, wipe it clean, and reinsert it to check the fluid level.
If the fluid is low, add the appropriate type of transmission fluid (refer to owner's manual for specification).
Inspect the fluid condition; if it’s dark or has a burnt smell, consider a fluid change.

4. Examine Electrical Connections

Reconnect the battery and perform a visual inspection of all wiring and connectors related to the transmission control module.
Use a multimeter to check for continuity and proper voltage at the transmission module connections.
Repair or replace any damaged wires or connectors as necessary.

5. Reprogram or Reset Module (if applicable)

If error codes indicate a need for reset, use the OBD-II scanner to clear error codes.
Follow manufacturer-specific procedures to reprogram the transmission control module if required.
