Replace the Filter:
- Remove the transmission pan bolts using a socket set.
- Carefully lower the transmission pan and remove the old filter.
- Install the new filter, ensuring it is seated properly.
Reinstall the Pan:
- Clean the mating surfaces on the transmission and pan.
- Apply a new gasket or sealant as required.
- Reinstall the transmission pan and torque the bolts to manufacturer specifications.

3. Fluid Refill

Add New Fluid:
- Using a funnel, pour the correct type of transmission fluid (as specified in the owner’s manual) into the filler tube.
- Start the vehicle and let it run for a few minutes, then check the fluid level with the dipstick; add more fluid if necessary.

4. Test Drive

Conduct a test drive to ensure proper operation and shifting of the transmission.
Monitor for any slipping or abnormal behavior.
