Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick or fill plug and check the fluid level.
3. If the fluid is low, add the recommended Toyota ATF (Toyota Genuine ATF WS).
4. If the fluid is dark or has a burnt smell, consider a complete fluid change.
5. To replace, drain the old fluid by removing the transmission pan (ensure a proper catch pan is used).
6. Replace the transmission filter if applicable.
7. Reinstall the transmission pan with a new gasket, torque the bolts to the manufacturer's specifications (around 10-15 ft-lbs).
8. Refill the transmission with the correct amount of ATF.

3. Inspect and Replace Transmission Control Module (if necessary)

Sub-steps:
1. Remove the TCM from its mounting location.
2. Inspect the TCM for visible damage or corrosion on connectors.
3. If damaged, replace it with a new TCM.
4. Reinstall the TCM, ensuring all connections are secure.

4. Test Transmission Solenoids

Sub-steps:
1. Remove the transmission solenoid assembly.
2. Use a multimeter to test the resistance of each solenoid according to the specifications provided in the service manual.
3. Replace any faulty solenoids as necessary.
4. Reinstall solenoids and ensure they are properly connected.
