The gasket may fatigue over time leading to the possibility of a leak into the combustion chamber after several thousand miles. Possible symptoms include: a check engine light for P0300 Misfire, possible combustion gas leaks to coolant resulting in overheating, over-flowed coolant bottle, milky-colored engine oil in the crankcase, piston scuffing and if the vehicle is continued to be driven in this condition, engine failure.

The supplier of the transmission-wiring harness introduced an unapproved change to the temperature sensor (thermistor), resulting in incorrect oil-temperature readings during transition from cold to warm temperatures. This could cause a harsh shift when starting the vehicle at temperatures below 32ºF (0ºC); however, shift quality improves once the transmission oil warms up. |
