If damaged, remove the old gasket/seal using a scraper.
Clean the sealing surfaces thoroughly.
Install a new gasket or seal, ensuring it is seated properly.

4. Repair or Replace the Transmission Pan

If the transmission pan is damaged, it may need to be replaced.
If only minor repairs are needed, clean the pan and apply a sealant as necessary.
Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.
