Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues during repairs.

2. Check and Replace Transmission Fluid

Tools Required: Transmission jack, funnel, drain pan, socket set
Locate the transmission fluid dipstick (if applicable) and check the fluid level.
If low or burnt, drain the old fluid into a drain pan and replace it with new fluid as per manufacturer specifications.
Refill with the appropriate fluid type (Toyota ATF WS) via the dipstick tube.

3. Inspect and Adjust Transmission Linkage

Tools Required: Wrench set, screwdriver
Remove any covers or panels obstructing access to the linkage.
Visually inspect the linkage for wear or damage; adjust or replace components as necessary.
Ensure all connections are secure and properly aligned.

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

Tools Required: Multimeter, diagnostic scanner
Use a multimeter to check the TCM for continuity and proper voltage.
If faulty, disconnect the wiring harness, remove the TCM, and replace it with a new unit.
Reconnect the wiring harness and clear any error codes with a diagnostic scanner.

5. Reassemble and Test

Reattach any covers or panels removed during the inspection and repair process.
Reconnect the battery, and start the vehicle.
Perform a test drive to ensure the transmission shifts smoothly through all gears.
