Also check for:

- Check the reverse brake pressure.
- Inspect the reverse brake piston and the O-rings. Check the spring retainer for wear and damage. Inspect the clearance between the reverse brake end-plate and the top disc. If the clearance is out of tolerance, inspect the reverse brake discs and plates for wear and damage. If the discs and plates are worn or damaged, replace them as a set. If they are OK, adjust the clearance with the reverse brake end-plate.
- Check the needle bearing and the thrust washers on the planetary carrier for wear and damage. If the needle bearing or thrust washer is worn or damaged, replace the bearing or washer, and adjust the clearance with the thrust shim.
- Check the CVTF level, and check the ATF cooler lines for leakage and loose connections. If necessary, clean the ATF cooler lines.
