Also check for:

- Check the drive and driven pulley pressure, and lubrication pressure. If the pressure is low or there is no pressure, check the ATF pump, the ATF pump chain, and the ATF pump sprocket.
- 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 for a stored DTC, and check for a loose solenoid harness connector.
- Check for a loose shift cable at the shift lever and the selector control lever.
- Check the CVTF level, and check the ATF cooler lines for leakage and loose connections. If necessary, clean the ATF cooler lines.
- Check for a stored DTC, and check for a loose transmission range switch connector.
