Transmission Heater Leakage Inspection

  1. If the engine is overheating and the transmission is shifting harshly from reverse to forward.
    1. Inspect the coolant in the pressurized coolant bottle and try to determine the type contamination, is the contamination transmission oil or engine oil?
    2. If transmission oil contamination is suspected then remove the transmission fill plug from the right rear of the transmission case and obtain a sample of the transmission fluid.
    3. Is the transmission fluid normal in color or is it milky in color?
    4. If the transmission fluid is milky in color then their is a very good chance the transmission heater has an internal leak.
