Late Shift After Shifting From N to R, or Excessive Shock When Shifting

Late shift after shifting from N to R, or excessive shock when shifting

Diagnostic Procedure:

1. Shift solenoid valve C defective

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

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

4. Shift cable broken or out of adjustment

5. Connection between shift cable and transmission or body is worn

6. Input shaft (mainshaft) speed sensor defective

7. Output shaft (countershaft) speed sensor defective

8. ATF temperature sensor defective

9. Shift fork shaft stuck

10. CPC valve C stuck

11. Reverse CPC valve defective

12. Foreign material in separator plate orifice

13. Shift valve E defective

14. 5th accumulator defective

15. 5th clutch defective

Also check for:

- Check for a stored DTC, and check for loose connectors.
- Inspect the O-ring, and check for a seized shift solenoid valve.
- Inspect the A/T clutch pressure control solenoid valve body gasket and ATF feed pipes for wear and damage. If the A/T clutch pressure control solenoid valve is stuck, inspect the CPC valves.
- Check for a loose shift cable at the shift lever and the transmission control lever.
- Inspect the sensor O-rings.
- Check the 5th clutch pressure.
- 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.
