Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and properly supported with jack stands.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check the fluid level. If low, add the recommended transmission fluid (Toyota WS).
2. If the fluid is dirty or burnt, prepare to replace it.
3. Locate and remove the transmission drain plug to drain old fluid into a suitable container.
4. Replace the drain plug and torque it to the manufacturer’s specifications (usually around 10-15 lb-ft).
5. Refill the transmission through the dipstick tube with fresh Toyota WS fluid until it reaches the proper level.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan bolts using a socket set and carefully lower the pan.
2. Inspect the pan for metal shavings or debris; clean as necessary.
3. Remove the old transmission filter and replace it with a new one.
4. Reinstall the transmission pan with a new gasket and torque to specifications (typically around 8-12 lb-ft).

4. Test and Replace Solenoids (if necessary)

Sub-steps:
1. Locate the transmission solenoids, typically found inside the transmission body or valve body.
2. Disconnect the electrical connectors and remove any mounting bolts.
3. Replace with new solenoids if they are faulty based on the diagnostic tests.
4. Reassemble components and reconnect electrical connectors.
