Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Refill Transmission Fluid

Tools Required: Transmission dipstick, funnel, transmission fluid (as specified in the owner’s manual)
Remove the dipstick and check the fluid level; add fluid if low.
Ensure the fluid is in good condition (not burnt or contaminated). If so, replace the fluid.

3. Inspect and Replace Brake Light Switch

Tools Required: Screwdriver, replacement brake light switch
Locate the brake light switch above the brake pedal.
Remove the retaining screws and disconnect the wiring harness.
Install the new switch and reconnect the wiring harness.
Test the switch operation before reassembling.

4. Inspect Transmission Linkage

Tools Required: Socket set, wrenches
Locate the transmission linkage connected to the gear shift lever.
Ensure all connections are secure and adjust as necessary.
Tighten any loose bolts or nuts.

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

Tools Required: OBD-II scanner, possible replacement TCM
Use the OBD-II scanner to check for TCM-related error codes.
If errors persist, remove the TCM from its housing and replace it with a new unit.
Reconnect the vehicle’s battery and clear error codes.
