Probable Cause(s)
  1. A/T clutch pressure control solenoid valve B defective
  2. A/T clutch pressure control solenoid valve C defective
  3. Input shaft (mainshaft) speed sensor defective
  4. Output shaft (countershaft) speed sensor defective

  6. Foreign material in separator plate orifice
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.
