Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface and the engine has cooled down.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Fluid pump
- Multimeter
- Transmission fluid (Toyota T-IV or equivalent)

2. Change Transmission Fluid and Filter

Drain Old Fluid
- Place a drain pan underneath the transmission pan.
- Remove the transmission pan bolts using a socket wrench.
- Allow the old fluid to drain completely.
Remove and Inspect Filter
- Remove the transmission filter by unbolting it. Inspect for any debris or damage.
- Clean the filter mounting surface.
Install New Filter
- Install the new transmission filter, ensuring it is seated properly. Tighten bolts to manufacturer specifications (usually around 9-12 ft-lbs, but refer to the service manual).
Clean the Transmission Pan
- Clean the transmission pan thoroughly to remove old gasket material. Ensure the surface is smooth for a proper seal.
Reinstall the Transmission Pan
- Place a new gasket on the pan and reinstall it. Tighten the bolts in a criss-cross pattern to the specified torque.
Refill Transmission Fluid
- Using a fluid pump, refill the transmission with new fluid through the dipstick tube. Refer to the vehicle's manual for the correct fluid quantity.

3. Verify Solenoids and Electrical Connections

Check Solenoids
- Disconnect the battery and access the transmission control module. Use a multimeter to test the solenoids for resistance as per specifications.
- Replace any faulty solenoids.
Inspect Electrical Connections
- Check for loose or corroded connectors and repair as necessary.
