Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If fluid is low, add the correct type of transmission fluid (refer to the owner’s manual).
If the fluid is contaminated or burnt, drain the transmission fluid using a fluid pump and replace it.
Refill with the correct amount of new transmission fluid.

3. Inspect and Repair Wiring

Remove the TCM connector.
Inspect the wiring harness for any signs of wear, fraying, or corrosion.
Repair or replace damaged wires as necessary.
Reconnect the TCM and make sure the connection is secure.

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

If the TCM tests show malfunction, remove the TCM from its mounting.
Disconnect the wiring harness from the TCM.
Install the new TCM, reconnect the wiring harness, and secure it.
Reconnect the battery.
