Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if applicable) or access the transmission fluid pan.
2. Remove the dipstick or drain plug, and check fluid color and level.
3. If the fluid is dark or burnt, drain the old transmission fluid into a suitable container.
4. Replace with new Toyota-approved transmission fluid (e.g., Toyota WS fluid).
5. Reinstall the dipstick or drain plug and torque to manufacturer specifications.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by loosening bolts with a socket set.
2. Carefully detach the pan and allow any remaining fluid to drain.
3. Remove the old transmission filter and replace it with a new one.
4. Clean the transmission pan and replace the gasket before reinstallation.
5. Reattach the transmission pan and torque bolts to manufacturer specifications.

4. Test and Replace Transmission Solenoids (if necessary)

Sub-steps:
1. Access the transmission solenoids as per service manual instructions.
2. Disconnect the electrical connectors and remove the solenoid assembly.
3. Test each solenoid's resistance with a multimeter (compare with specifications).
4. Replace any faulty solenoids with new ones.
5. Reassemble the components and reconnect electrical connectors.
