Poor acceleration; flares when starting off in D and R; stall speed high in D, 2, and 1

Diagnostic Procedure:

1. 1st accumulator defective

2. 1st clutch defective

Also check for:

- Check the 1st clutch pressure.
- Inspect the 1st clutch for wear and damage.
- Inspect the clutch piston, the clutch piston check valve, and the O-rings. Check the spring retainer for wear, damage, and peeling. 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 the tolerance, replace the wave-plate. If they are OK, adjust the clearance with the clutch end-plate.
- Check the 1st accumulator piston, O-ring, and spring in the accumulator body for wear and damage.
