Foreign material in separator plate orifice

1st accumulator defective

2nd accumulator defective

1st check ball stuck

2nd check ball stuck

Lock-up shift valve defective

1st clutch defective

2nd clutch defective

Notes

Test shift solenoid valve E with the HDS Shift Solenoid Valve Test, Replacement, And Shift Solenoid Wire Harness Replacement.

Notes

Inspect the O-ring, and check for a seized shift solenoid valve.

Notes

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

Notes

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

Notes

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

Notes

Check for a clogged orifice in the transmission fluid pressure switch connector. If the orifice is clogged, remove it and clean the connector.

Notes

Check the 1st and 2nd clutch pressures A/T Pressure Test.

Notes

Check the 1st accumulator piston, the O-ring, and the spring in the regulator valve body for wear and damage.

Notes

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

Notes

Check the lock-up shift valve in the regulator valve body for free movement, and check the valve spring 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 flat-plates are worn or damaged, replace the discs and the flat-plates as a set. If the wave-plate 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.
