Notes

Check the engine and transmission mounts.

Notes

Inspect shift solenoid valve E for seizure, and the O-rings for wear and damage.

Notes

Inspect A/T clutch pressure control solenoid valves A, B, and C filter/gasket and the O-rings for wear and damage, and inspect the solenoid valves for seizure.

Notes

Check the input shaft (mainshaft) speed sensor and the output shaft (countershaft) speed sensor installation.

Notes

Check for a loose shift cable at the shift lever and the selector control lever.

Notes

Check the 1st clutch pressure A/T Pressure Test.

Notes

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.

Notes

Inspect the 1st clutch feed pipe. If the 1st clutch feed pipe is scored, replace the end cover.

Notes

Replace the secondary shaft if the bushing for the 1st clutch feed pipe is loose or damaged.
