Late Shift After Shifting From N to D and D3, or Excessive Shock When Shifted Into D and D3

Late shift after shifting from N to D and D3, or excessive shock when shifted into D and D3

Diagnostic Procedure:

1. Shift solenoid valve E defective

2. A/T clutch pressure control solenoid valve A defective

3. A/T clutch pressure control solenoid valve B defective

4. A/T clutch pressure control solenoid valve C defective

5. Shift cable broken or out of adjustment

6. Connection between the shift cable and transmission or body is worn

7. Input shaft (mainshaft) speed sensor defective

8. Output shaft (countershaft) speed sensor defective

9. ATF temperature sensor defective

10. Foreign material in separator plate orifice

11. Servo control valve defective

12. 1st accumulator defective

13. 1st check ball stuck

14. Lock-up shift valve defective

15. 1st clutch defective

Also check for:

- Check for a stored DTC, and check for loose connectors.
- Inspect shift solenoid valve E for seizure, and the O-rings for wear and damage.
- Inspect A/T clutch pressure control solenoid valves A, B, and C filter/gasket and the O-rings for wear and damage, and inspect the solenoid valves for seizure.
- Check the input shaft (mainshaft) speed sensor and the output shaft (countershaft) speed sensor installation.
- Check for a loose shift cable at the shift lever and the selector control shaft.
- Check the 1st clutch pressure.
- Inspect the clutch piston, the clutch piston check valve, and the O-rings. Check the spring retainer and the retainer seal 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. If the discs are worn or damaged, replace them as a set. Inspect the clutch wave-plate height. If the 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.
- Inspect the 1st clutch feed pipe. If the 1st clutch feed pipe is scored, replace the end cover.
- Replace the secondary shaft if the bushing for the 1st clutch feed pipe is loose or damaged.
