Late shift after shifting from N to D and S, or excessive shock when shifted into D and S
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. Connection between 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
Notes
  • Check for a stored DTC, and check for loose connectors.
  • Inspect the solenoid valve 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 transmission 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.
