Excessive shock or flares on 2-3 upshift or 3-2 downshift

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

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

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

Notes

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

Notes

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

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

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.
