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

Diagnostic Procedure:

1. 2nd accumulator defective

2. 2nd gears worn or damaged

3. 2nd clutch defective

Also check for:

- Inspect the 2nd accumulator piston, the O-ring, and the spring for wear and damaged in the servo body.
- Check the 2nd clutch pressure.
- Inspect the countershaft, the secondary shaft, and the 2nd clutch for wear and damage.
- 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 the plates for wear and damage, and inspect the clutch wave-plate height. If the discs and the plates are worn or damaged, replace them as a set. If the wave-plate height is out of tolerance, replace the wave-plate. If they are OK, adjust the clearance with the clutch end-plate.
- Inspect the 2nd clutch feed pipe. If the 2nd clutch feed pipe is scored, replace the end cover.
- Replace the secondary shaft if the bushing for the 2nd clutch feed pipe is loose or damaged.
