- Remove the old gasket and clean the surfaces thoroughly.
- Install the new gasket and reattach the pan, torquing the bolts to the manufacturer's specifications.
Seal Replacement:
- If leaks are found at a seal, remove the affected component (e.g., output shaft or input shaft).
- Replace the old seal with a new one, ensuring proper seating.
Line Replacement:
- If cooler lines are damaged, detach the lines and replace them with new ones, ensuring all connections are tight.

4. Refill and Test
