Solution

1. Preparation

Gather necessary tools and components.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the battery to avoid electrical issues during repairs.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, fluid catch pan, socket set.
Remove the transmission fluid drain plug using a socket.
Allow old fluid to drain completely into the catch pan.
Inspect the drained fluid for metal shavings or burnt smell.
Replace with the manufacturer-recommended transmission fluid using the pump.
Reinstall the drain plug and torque to manufacturer specifications.

3. Inspect and Replace Transmission Control Module (if necessary)

Tools Required: Screwdrivers, socket set, multimeter.
Remove the dashboard cover or panel to access the TCM.
Disconnect the TCM wiring harness carefully.
Use a multimeter to test the TCM for proper voltage and continuity.
If faulty, remove the TCM by unscrewing it from its mounting location.
Install the new TCM, reconnect the wiring harness, and secure it in place.

4. Adjust Transmission Linkage

Tools Required: Wrench set, socket set.
Locate the transmission linkage under the vehicle.
Inspect for any misalignment or damage; adjust or replace as necessary.
Ensure the linkage is securely fastened and operates smoothly when shifting.
