4. Reinstall the fill plug securely.

3. Inspect and Replace Transmission Filter (if applicable)

Tools Required: Socket set, transmission filter kit.
Steps:
1. Remove the transmission pan by loosening the bolts with a socket set.
2. Carefully lower the pan and remove the old filter.
3. Install the new filter, ensuring it is seated properly.
4. Clean the transmission pan and install it back with a new gasket, tightening bolts to the specified torque.

4. Check and Replace Transmission Solenoids

Tools Required: Socket set, multimeter.
Steps:
1. Locate the transmission solenoids (refer to the service manual for exact location).
2. Disconnect the electrical connectors and remove the solenoids.
3. Test solenoids with a multimeter; replace any that do not meet specifications.
