Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Secure the vehicle with wheel chocks and jack stands if needed.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick and check the fluid level; add fluid if low.
Inspect the fluid condition; if dark or burnt, proceed to change it.
Drain the old transmission fluid by removing the drain plug (if equipped).
Replace the transmission filter if applicable.
Refill with manufacturer-recommended transmission fluid through the dipstick or fill plug.

3. Inspect and Adjust Gear Linkage

Locate the gear linkage assembly.
Inspect for any signs of wear or damage.
If misaligned, adjust the linkage according to the service manual specifications.
Tighten any loose bolts or connections.

4. Test and Replace Transmission Control Module (if necessary)

Disconnect the electrical connector from the TCM.
Use a multimeter to test for proper voltage and signals.
If the TCM is faulty, replace it with a new unit.
Reconnect the TCM and clear any diagnostic codes.
