Also check for:
- Check the forward clutch pressure.
- Inspect the clutch piston, the clutch piston check valve, and the O-rings. Check the spring retainer for wear and damage. Inspect the clearance between the clutch end-plate and the top disc. If the clearance is out of tolerance, inspect the clutch 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 clutch end-plate.
- Check for a loose shift cable at the shift lever and the selector control lever.
- Check the reverse brake pressure.
- Inspect the brake piston and the O-rings. Check the spring retainer for wear and damage. Inspect the clearance between the brake end-plate and the top disc. If the clearance is out of tolerance, inspect the 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 brake end-plate.
- Check the needle bearing and the thrust washers on the planetary carrier for wear and damage. If the needle bearing or the thrust washer is worn or damaged, replace the bearing or the washer, and adjust the clearance with the thrust shim.
- Check for a stored DTC, and check for a loose solenoid harness connector and the transmission range switch connector.
