Solution

1. Preparation

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

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert it back and check the fluid level; add appropriate Toyota ATF if low.
If fluid is dark or smells burnt, proceed to fluid change.

3. Change Transmission Fluid and Filter

Tools Required: Socket set, torque wrench, transmission jack, fluid pump.
Sub-steps:
1. Drain the old transmission fluid by removing the drain plug or pan.
2. Remove the transmission pan bolts and carefully detach the pan.
3. Remove the old filter and replace it with a new one.
4. Clean the transmission pan and replace the gasket.
5. Reinstall the pan and torque bolts to manufacturer specifications (typically 10-12 ft-lbs).
6. Refill the transmission with new Toyota ATF through the dipstick tube.

4. Inspect and Repair Wiring

Inspect the wiring harness for any damaged insulation or frayed wires.
Repair or replace any damaged connectors and ensure all connections are secure.

5. Replace TCM (if necessary)

If the TCM is determined to be faulty, remove the mounting bolts and disconnect the harness.
Install the new TCM and secure it in place, reconnecting all wiring as per specifications.
