Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical accidents.

2. Check and Change Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe the dipstick clean and reinsert it to check the fluid level.
If the fluid is low or discolored, proceed to drain and replace it:
- Remove the drain plug with a socket set and allow fluid to drain completely.
- Dispose of old fluid properly.
Replace with the recommended transmission fluid (typically Toyota Type T-IV) and fill to the appropriate level.

3. Replace Transmission Filter

Remove the transmission pan using a socket set.
- Note: Some fluid will spill, so have a drain pan ready.
Carefully remove the old filter from the valve body.
Install the new filter, ensuring it is seated correctly.
Clean the transmission pan and replace the gasket to prevent leaks.
Reattach the transmission pan and torque the bolts to manufacturer specifications.

4. Test Transmission Solenoids

Disconnect the electrical connector from the solenoids.
Use a multimeter to test the resistance of each solenoid.
- Compare readings to specifications in the service manual.
Replace any faulty solenoids with new components.
