5. Inspect the pan for metal shavings or debris indicating internal wear.
6. Replace the transmission filter as per manufacturer specifications.
7. Reinstall the transmission pan with a new gasket, tightening bolts to manufacturer torque specifications.

3. Inspect and Test Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids; refer to the service manual for specific location details.
2. Disconnect the electrical connectors from the solenoids.
3. Use a multimeter to test each solenoid for resistance; compare results to manufacturer specifications.
4. Replace any faulty solenoids.

4. Assess Clutch Plates/Bands (if applicable)

Sub-steps:
