Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Ensure the vehicle is on a level surface and safely elevated on jack stands.
Disconnect the battery to avoid electrical shorts.

2. Change Transmission Fluid and Filter

Drain Old Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Allow old fluid to completely drain.
Replace Filter
- Remove the old transmission filter and discard it.
- Install a new transmission filter, ensuring it is seated properly.
Clean Transmission Pan
- Thoroughly clean the transmission pan to remove debris and old gasket material.
- Inspect the pan for cracks or damage; replace if necessary.
Install New Gasket
- Place a new gasket onto the transmission pan or apply gasket maker if required.
Reinstall Transmission Pan
- Reattach the transmission pan using the original bolts, torquing them to the manufacturer's specifications (typically around 10-12 ft-lbs).
- Ensure there are no gaps and that the gasket is properly aligned.
Refill Transmission Fluid
- Use the appropriate Toyota transmission fluid (typically Toyota WS fluid).
- Pour fluid through the dipstick tube until the proper level is reached, checking with the dipstick.

3. Inspect and Replace Solenoids (if necessary)

Locate Solenoids
- Access the transmission solenoids by removing the transmission pan again if they are internal.
- Disconnect the electrical connectors from the solenoids.
Remove and Replace
- Remove the old solenoids and install the new ones.
- Reconnect the electrical connectors securely.
