Transmission Heater Leakage Inspection
- If the engine is overheating and the transmission is shifting harshly from reverse to forward.
- Inspect the coolant in the pressurized coolant bottle and try to determine the type contamination, is the contamination transmission oil or engine oil?
- 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.
- Is the transmission fluid normal in color or is it milky in color?
- If the transmission fluid is milky in color then their is a very good chance the transmission heater has an internal leak.
