Solution

1. Preparation

Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery's negative terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Check and Change Transmission Fluid

Tools Required: Socket set, fluid pump, torque wrench, transmission fluid (as specified in owner's manual).
Remove the transmission pan using a socket set.
Inspect the old fluid for metal shavings or debris; replace the fluid if contaminated.
Clean the pan and replace the filter if necessary.
Reinstall the pan using a new gasket and torque to manufacturer specifications (typically around 10-15 ft-lbs).
Fill the transmission with the recommended fluid type until it reaches the proper level.

3. Adjust Transmission Linkage

Tools Required: Wrench set, screwdriver.
Inspect the linkage for proper alignment and wear.
If misaligned, adjust the linkage according to the vehicle's service manual specifications.
Tighten all fasteners securely.

4. Reprogram or Replace TCM (if necessary)

Tools Required: OBD-II scanner, laptop or diagnostic tool.
If the TCM is faulty, replace it with a new unit.
Reprogram the new TCM with the latest software using an appropriate diagnostic tool.

5. Reconnect Battery

Reconnect the negative terminal of the battery after all repairs are completed.
