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.

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.

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

Inspect the A/T clutch pressure control solenoid valve body gasket, the ATF pipes, the ATF joint pipe, 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

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

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, and the regulator valve body for wear and damage.

Notes

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