5. Replace the transmission filter if applicable, and reassemble the pan with a new gasket.

3. Inspect and Repair Transmission Components

Sub-steps:
1. Examine the transmission linkage for any signs of wear or damage; adjust or replace as necessary.
2. Inspect the transmission mounts for deterioration; replace if they are worn or cracked.
3. Check for any external leaks around seals or gaskets; replace any faulty seals.
4. If no external issues are found, consider having the transmission control module (TCM) calibrated or replaced if error codes indicate a fault.
