  • Check the drive and driven pulley pressure and lubrication pressure. Measurement of the pressure is low or no pressure, check the ATF pump, chain and sprocket.
  • Check the forward clutch pressure.
  • Check the indicator light indication and check for loose solenoid harness connector.
  • Inspect the clutch piston, clutch piston check valve and O-rings. Check the spring retainer 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 and plates are worn or damaged, replace them as a set. If they are OK, adjust the clearance with the clutch end plate.
  • Check the indicator light indication and check for loose solenoid harness connector.
  • Calibrate start clutch control system.
