My chevy cobalt got up to 215 but i was driving a long distance and the temperature outside was around 95-100 is 215 to hot for my car?
Normal operating ranges are from 175-200. 215 isn't bad for short durations, but higher temperatures can break down the oil at a faster rate and require a change sooner than recommended. Automatic transmission oil can provide up to 100,000 miles of service before oxidation requires replacement, at an operating temperature of 175. Above this temperature, the oil oxidation rate doubles with each 20 degrees F increase in oil temperature.
