Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Insert the dipstick back into the tube and remove it again to check the fluid level.
3. If the fluid is low, add the proper type of transmission fluid (Toyota ATF WS).
4. If fluid is contaminated, drain the transmission fluid using a drain pan.
5. Replace the transmission fluid filter by removing the pan and unscrewing the filter.
6. Install a new filter, reattach the pan using a new gasket, and refill with fresh transmission fluid.

3. Inspect and Repair Wiring Harness

Sub-steps:
1. Locate the transmission wiring harness and visually inspect for frayed wires or loose connections.
2. Use a multimeter to test continuity in the wiring.
3. Repair or replace damaged wires or connectors as necessary.

4. Test Transmission Control Module

Sub-steps:
1. Reconnect the battery.
2. Use a diagnostic tool to access the TCM and check for any faults.
3. If necessary, update the TCM software or replace the module if it is faulty.
