If applicable, remove the transmission filter located inside the transmission assembly.
Inspect the filter for debris and damage; replace if necessary.

4. Clean Transmission Pan

Clean the transmission pan thoroughly with a suitable cleaner to remove any sludge or debris.
Inspect the magnet inside the pan for metal shavings; clean it if present.

5. Install New Filter and Reassemble

Install the new transmission filter, ensuring it is seated properly.
Reattach the transmission pan with a new gasket, if required, and tighten the bolts to the manufacturer’s specified torque values.

6. Fill Transmission with New Fluid

Use a transmission fluid pump to fill the transmission with the correct type and amount of new fluid as specified in the owner's manual.
Start the engine and cycle through all gears to circulate the new fluid.

7. Check for Leaks
