3. Check the valve body for proper operation and clean if necessary.
4. Reassemble the transmission pan and ensure all bolts are torqued to factory specifications.

4. Recheck Fluid Levels and Test Drive

After repairs, check the fluid level again and adjust if necessary.
Start the engine and allow it to warm up.
Test drive the vehicle to ensure that the slipping condition has been resolved.
