Remove the transmission pan by loosening the bolts with a socket set.
Carefully lower the pan and remove the old filter.
Install the new filter, ensuring it is properly seated.

4. Reinstall Transmission Pan

Clean the mating surfaces of the transmission and the pan.
Apply a new gasket or RTV sealant as per manufacturer specifications.
Reattach the transmission pan and torque the bolts to the specified value (consult the service manual for the torque specification).

5. Refill Transmission Fluid

Use a funnel to add new transmission fluid through the dipstick tube (if applicable).
Consult the owner's manual for the correct type of fluid and the required amount.
