A/T clutch pressure control solenoid valve B defective

A/T clutch pressure control solenoid valve C defective

Transmission fluid pressure switch B (3rd clutch) defective

Shift fork shaft stuck

Servo control valve defective

CPC valve A defective

CPC valve B defective

Lock-up shift valve defective

Foreign material in separator plate orifice

2nd accumulator defective

3rd accumulator defective

2nd check ball stuck

2nd clutch defective

3rd clutch defective

Clearance between clutch end-plate and top disc incorrect

Notes

Check the engine and transmission mounts.

Notes

Test the transmission fluid pressure switch B (3rd clutch) operation with the HDS.

Notes

Test the shift solenoid valve function with the HDS Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement (A/T).

Notes

Test A/T clutch pressure control solenoid valve A or B with the HDS A/T Clutch Pressure Control Solenoid Valve A and B Test (A/T).

Notes

Test A/T clutch pressure control solenoid valve C with the HDS A/T Clutch Pressure Control Solenoid Valve C Test.

Notes

Check for a seized shift solenoid valve, and inspect the O-rings.

Notes

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

Notes

Inspect the A/T clutch pressure control solenoid valve body gasket, the ATF feed pipes, and the O-rings for wear and damage.

Notes

Check for a missing shift fork bolt on the shift fork shaft.

Notes

Check the shift fork shaft detent for wear and damage.

Notes

Check for a stuck servo valve in the regulator valve body, and check the O-ring for wear and damage.

Notes

Check the servo control valve, CPC valve A, and the lock-up shift valve in the main valve body for free movement, and check the valve springs for wear and damage.

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 CPC valve B in the secondary valve body for free movement, and check the valve spring for wear and damage.

Notes

Inspect the 2nd and 3rd clutches for wear and damage.

Notes

Inspect the clutch piston, the clutch piston check valve, and the 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 the plates for wear and damage, and inspect the clutch wave-plate height. If the discs and the plates are worn or damaged, replace them as a set. If the clutch wave-plate height is out of the tolerance, replace the clutch wave-plate. If they are OK, adjust the clearance with the clutch end-plate.

Notes

Check the 2nd and 3rd accumulator pistons, the O-rings, and the springs in the accumulator body for wear and damage.

Notes

Check for a stuck 2nd check ball in the secondary valve body.
