Notes
Check the 2nd clutch pressure.
Inspect the 2nd accumulator piston, O-ring, and spring for wear and damaged in the servo body.
Inspect the countershaft, secondary shaft, and 2nd clutch for wear and damage.
Inspect the clutch piston, clutch piston check valve, and 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, and inspect the clutch wave-plate height. If the discs and 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.
