Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery before starting work on the electrical components.

2. Address Fluid Levels

Tools Required: Transmission fluid pump, funnel
Check and top off the transmission fluid if low. If the fluid is dark or smells burnt, consider a fluid change.
Use the manufacturer-recommended transmission fluid type.

3. Inspect and Repair Transmission Linkage

Tools Required: Socket set, wrenches
Locate the transmission linkage under the vehicle.
Inspect for any loose, worn, or damaged components. Tighten or replace as necessary.

4. Replace Transmission Control Module (if necessary)

Tools Required: Socket set, Torx screwdriver
If error codes indicate a faulty TCM, remove the old module by unbolting it from its bracket.
Disconnect the electrical connectors and install the new TCM.
Reconnect the battery and clear any error codes.

5. Test Drive and Adjust as Necessary

After repairs, conduct a test drive to ensure proper shifting and operation.
Monitor the vehicle for any signs of the original issue to confirm the resolution.
