Excessive Shock or Flares on 1-2 Upshift or 2-1 Downshift

Excessive shock or flares on 1-2 upshift or 2-1 downshift

Worn or damaged engine or transmission mounts

Shift solenoid valve A defective

Shift solenoid valve C defective

Shift solenoid valve D defective

A/T clutch pressure control solenoid valve A defective

A/T clutch pressure control solenoid valve B defective

A/T clutch pressure control solenoid valve C defective

Transmission fluid pressure switch A (2nd clutch) defective

CPC valve A defective

CPC valve B defective

CPC valve C defective

Shift valve C defective

Shift valve D defective

Foreign material in separator plate orifice

2nd accumulator defective

2nd 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 A (2nd 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 clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice.

Notes

Check CPC valve A in the main valve body for free movement, and check the valve spring for wear and damage.

Notes

Check CPC valves B and C in the secondary valve body for free movement, and check the valve springs for wear and damage.

Notes

Check shift valves C and D in the secondary valve body for free movement, and check the valve springs for wear and damage.

Notes

Check the 2nd clutch pressure A/T Pressure Test.

Notes

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