Remove the transmission pan by unscrewing the bolts with a socket set.
Carefully lower the pan and remove the old filter from the transmission.
Install the new filter according to specifications and secure it in place.

4. Clean the Transmission Pan

Clean the inside of the transmission pan thoroughly using a solvent.
Replace the pan gasket before reattaching the pan to prevent leaks.
Torque the bolts to the specified value in a crisscross pattern.
