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

Probable cause(s)

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. Joint in shift cable and transmission or body 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

Notes

- Check the D indicator, and check for loose connectors. Inspect the solenoid valve filter/gasket and O-rings for wear and damage, and inspect the solenoid valves for seizure.
- Check the input shaft (mainshaft) speed sensor and output shaft (countershaft) speed sensor installation.
- Check for a loose shift cable at the shift lever and the transmission control shaft.
- Check the 1st clutch pressure.
- Inspect the clutch piston, clutch piston check valve, and O-rings. Check the spring retainer and retainer seal for wear and damage. Inspect the clutch end-plate-to-top-disc clearance. If the clearance is out of tolerance, inspect the clutch discs and plates for wear and damage. If the discs are worn or damaged, replace the discs as a set. Inspect the clutch waved-plate height. If the height is out of tolerance, replace the waved-plate. If the discs and 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.
