Clean the mounting surface thoroughly using a lint-free cloth.
Install the new transmission filter, ensuring it is seated properly.

4. Reinstall Transmission Pan

Clean the transmission pan and inspect for any damage.
Apply a new gasket or sealant as per the manufacturer's specifications.
Reattach the pan to the transmission and torque the bolts to the manufacturer’s specifications (usually around 8-10 ft-lbs).

5. Fill with New Transmission Fluid

Tools Required: Funnel.
Locate the transmission dipstick tube and insert a funnel.
Pour new, manufacturer-recommended transmission fluid into the tube until the fluid level reaches the recommended mark on the dipstick.
