Notes

Check the engine and transmission mounts.

Notes

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

Notes

Check the 2nd and 3rd clutch pressures A/T Pressure Test.

Notes

Check for a clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice.

Notes

Inspect the clutch piston, the clutch piston check valve, and the O-rings. Check the spring retainer and the retainer seal 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. 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 3rd clutch feed pipe. If the 3rd clutch feed pipe is scored, replace it and the O-ring under the feed pipe guide.

Notes

Replace the secondary shaft if the bushing for the 3rd clutch feed pipe is loose or damaged.

Notes

Check the 2nd accumulator piston, the O-ring, and the springs in the servo valve body for wear and damage.

Notes

Check the 3rd accumulator piston, the O-ring, and the springs in the regulator valve body for wear and damage.
