Delayed Engagement After Shifting From N To D And D3 Or Excessive Shock When Shifted Into D And D3 (A/T)

Delayed engagement after shifting from N to D and D3 or excessive shock when shifted into D and D3

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

Shift cable broken or out of adjustment

Connection between shift cable and transmission or body is worn

Input shaft (mainshaft) speed sensor defective

Output shaft (countershaft) speed sensor defective

ATF temperature sensor defective

Foreign material in separator plate orifice

Servo control valve defective

1st accumulator defective

1st check ball stuck

Lock-up shift valve defective

1st clutch defective

Notes

Test the solenoid valve function with the HDS.

Notes

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

Notes

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

Notes

Check the input shaft (mainshaft) speed sensor and the output shaft (countershaft) speed sensor installation. 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 ATF strainer for debris. If the strainer is clogged with particles of steel or aluminum, inspect the ATF pump. If the ATF pump is OK, find the damaged components that caused the debris. If no cause for contamination is found, replace the torque converter.

Notes

Check the servo control valve in the main valve body.

Notes

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

Notes

Check that the 1st check ball is not stuck in the main valve body.

Notes

Check the lock-up shift valve in the regulator valve body.

Notes

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

Notes

Inspect the secondary shaft and the 1st 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 wave-plate height is out of tolerance, replace the wave-plate. If they are OK, adjust the clearance with the clutch end-plate.
