Clean the mounting surface on the valve body.
Install the new transmission filter, ensuring it is seated properly.

4. Reinstall Transmission Pan

Clean the transmission pan and remove any old gasket material.
Apply a new gasket or RTV sealant as per manufacturer specifications.
Reattach the transmission pan and torque the bolts to the specified torque value (typically around 8-12 ft-lbs).

5. Refill Transmission Fluid

Using a fluid pump, refill the transmission with the appropriate type and amount of new transmission fluid (refer to the owner's manual for specifications).
Start the engine and let it idle for a few minutes while checking for leaks.
Check the fluid level again and add more if necessary.
