Delayed engagement after shifting from N to D, or excessive shock when shifting

Worn engine or transmission mounts

Shift solenoid valve A defective

Shift solenoid valve B defective

Shift solenoid valve C defective

A/T clutch pressure control solenoid valve C defective

Shift cable broken or out of adjustment

Connection between shift cable and transmission or shift lever is worn

ATF temperature sensor defective

CPC valve C stuck

ATF strainer clogged

Foreign material in separator plate orifice

Shift valve A defective

Shift valve D defective

Servo control valve defective

1st accumulator defective

2nd accumulator defective

1st check ball stuck

1st clutch defective

Clearance between clutch end-plate and top disc incorrect

Notes

Check the engine and transmission mounts.

Notes

Test the shift solenoid valves with the HDS Service and Repair.

Notes

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

Notes

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

Notes

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

Notes

Check for a loose shift cable at the shift lever and the selector control lever.

Notes

Inspect the sensor O-ring 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 the stall speed A/T Stall Speed Test.

Notes

Check the line pressure A/T Pressure Test.

Notes

Check the ATF strainer for debris. If the strainer is clogged, find the damaged components that caused the debris. If no cause for contamination is found, replace the torque converter.

Notes

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

Notes

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

Notes

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

Notes

Check the 1st clutch pressure A/T Pressure Test.

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 wave-plate height is out of tolerance, replace the wave-plate. If they are OK, adjust the clearance with the clutch end-plate.

Notes

Check the 1st and 2nd accumulator piston, the O-ring, and the springs in the accumulator body for wear and damage.

Notes

Check for a stuck 1st check ball in the secondary valve body.
