Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Change Transmission Fluid

Sub-steps:
- Locate the transmission fluid pan and drain plug.
- Place a drain pan underneath and remove the drain plug to let old fluid drain.
- Replace the drain plug with a new gasket and torque to manufacturer specifications.
- Remove the transmission fluid dipstick and fill the transmission with new fluid using a funnel, ensuring to use the recommended type (typically Toyota WS fluid).
- Start the engine and let it warm up, then check fluid levels and add more if necessary.

3. Inspect and Adjust Gear Linkage

Sub-steps:
- Locate the gear shift linkage under the hood.
- Check for any loose or damaged components.
- Adjust the linkage according to the manufacturer’s specifications to ensure proper alignment.

4. Repair or Replace Transmission Control Module (TCM)

Sub-steps:
- Disconnect the battery and locate the TCM (usually near the transmission).
- Remove the TCM from its mounting location.
- Inspect the TCM for corrosion or damage; if faulty, replace it with a new unit, ensuring proper programming if necessary.
- Reconnect the battery.

5. Test Drive

Sub-steps:
- After completing repairs, perform a test drive to confirm the gear shifting issue is resolved.
- Monitor for any unusual noises or behavior during shifting.
