Vehicle moves in 2 and R, but not in D, D3, or 1

Diagnostic Procedure:

1. 1st accumulator defective

2. 1st gears worn or damaged

3. 1st clutch defective

Also check for:

- Check the 1st clutch pressure.
- Inspect the clutch piston, the clutch piston check valve, and the O-rings. Check the spring retainer and the retainer seal 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 the plates for wear and damage. If the discs are worn or damaged, replace them as a set. Inspect the clutch wave-plate height. If the height is out of tolerance, replace the wave-plate. If the discs and the plates are OK, adjust the clearance with the clutch end-plate.
- Inspect the 1st clutch feed pipe. If the 1st clutch feed pipe is scored, replace the end cover.
- Replace the secondary shaft if the bushing for the 1st clutch feed pipe is loose or damaged.
