- 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.
- Inspect the differential pinion shaft for wear under the pinion gears. If the differential pinion shaft is worn, overhaul the differential assembly, replace the ATF strainer, thoroughly clean the transmission and flush the torque converter, cooler and lines.
- Check ATF level and check ATF cooler lines for leakage and loose connections. If necessary, flush ATF cooler lines.
- If the strainer is clogged, find the damaged components that caused debris.
- Check the
 indicator light indication and check for loose solenoid harness connector.
