Inspect the transmission pan and surrounding areas for fluid leakage.
If the pan gasket is leaking, proceed to remove the transmission pan.

4. Remove Transmission Pan

Tools Required: Socket set, torque wrench, scraper
Remove the bolts holding the transmission pan using the socket set.
Carefully lower the pan to avoid spilling fluid.
Clean the surface of the transmission housing with a scraper to remove old gasket material.
