Sub-steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick; check the fluid level and condition.
3. If fluid is low or contaminated, drain the transmission fluid using a fluid pump.
4. Replace with the manufacturer-recommended transmission fluid (Toyota ATF WS).
5. Recheck the fluid level after filling.

3. Inspect and Repair Transmission Control Module (TCM)

Sub-steps:
1. Remove any necessary panels to access the TCM.
2. Disconnect the TCM wiring harness.
3. Inspect the connectors for corrosion or damage; clean if needed.
4. Reconnect the TCM and, if necessary, reprogram or replace it based on diagnostic codes.

4. Adjust or Replace Shift Linkage

Sub-steps:
1. Inspect the shift linkage for misalignment or damage.
2. Adjust the linkage as needed to ensure proper alignment.
3. If damaged, remove the old linkage and replace it with a new part.
