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 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 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, 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
Check for a clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice.
Notes
Check the servo control valve in the main valve body for free movement, and check the servo control valve spring for wear and damage.
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.
Notes
Check the 1st accumulator piston, the O-ring, and the springs in the regulator valve body for wear and damage.
Notes
Check the lock-up shift valve in the regulator valve body for free movement, and check the lock-up shift valve spring for wear and damage.
