Tools Required: Socket set, fluid pump, transmission fluid (Dexron VI or as specified in the owner's manual), new transmission filter, drain pan.
Remove the transmission pan bolts and gently drop the pan to drain the old fluid into the pan.
Replace the transmission filter and clean the pan magnet to remove metal shavings.
Reinstall the pan with a new gasket, ensuring all bolts are tightened to the manufacturer's torque specifications.

3. Fluid Level Check

With the engine running and the transmission in park, use a funnel to add fresh transmission fluid through the dipstick tube until the correct level is reached, as indicated on the dipstick.
