While installing an inline transmission filter I discovered that the fluid looked brown and worn, given that the car only has 10,000 miles. As a result, these seals leak both pressure and liquid. The most common problem for this model year was total transmission failure which occurred for a number of drivers around a hundred thousand miles. As a general rule, oils have a fairly narrow normal operating range, roughly 160F-240F.. It's not likely that CVT's will operate at a significantly higher temperature than other oil lubricated equipment. Just me in the car, no cargo, not towing.
