Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues during service.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and inspect fluid color and level.
2. If fluid is low or dirty, drain the old transmission fluid using a fluid extractor.
3. Replace the transmission filter:
  - Remove the transmission pan bolts using a socket set.
  - Carefully lower the pan and remove the filter.
  - Install the new filter, ensuring it is seated properly.
4. Reinstall the transmission pan, applying a new gasket if necessary, and torque bolts to the manufacturer’s specifications (typically around 8-10 ft-lbs).
5. Refill the transmission with new fluid (use Toyota ATF WS) through the dipstick tube, following the recommended capacity.

3. Inspect and Adjust Shift Linkage

Sub-steps:
1. Ensure the vehicle is in Park; inspect the shift linkage for any looseness or misalignment.
2. Adjust the shift linkage according to the service manual specifications if necessary.
3. Verify that the linkage moves freely without obstruction.

4. Check Transmission Pressure

Sub-steps:
1. Connect a transmission pressure gauge to the appropriate test port.
2. Start the engine and cycle through the gears, noting the pressure readings.
3. If pressure readings are low or inconsistent, further inspection of the valve body or internal components may be required.
