Check the 1st clutch pressure.
Inspect the clutch piston, clutch piston check valve, and O-rings. Check the spring retainer and retainer seal for wear and damage. Inspect the clutch end-plate-to-top-disc clearance. If the clearance is out of tolerance, inspect the clutch discs and plates for wear and damage. If the discs are worn or damaged, replace the discs as a set. Inspect the clutch waved-plate height. If the height is out of tolerance, replace the waved-plate. If the discs and plates are OK, adjust the clearance with the clutch and 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.
