The parts of the gearbox rub against each other and the subsequent friction creates a great amount of internal heat. Normal running CVT temp is 140 - 210 F, so you can't just warm it up and hope you are at the right temp. A couple of observations on this discussion: I'm using a ScanGauge II plugged into the ALDL port that's under the dash. . Overheat destroys the fluids lubricating qualities and the ability to friction. Please post tranny temps (range) you observe when you start towing. Also, at this temp there are no error codes or check engine lights. To understand the operating characteristics of a CVT we need to understand why CVTs were developed and what they are designed to accomplish. I google'd it but since many WRX's did not have oil temp gauges previously, the choosing of whether or not they should install these gauges dominated the discussion lol. acceleration and lower RPM for better fuel economy while cruising.

Lineatronic delivers a smoother ride while also reducing mechanical noise While installing an inline transmission filter I discovered that the fluid looked brown and worn, given that the car only has 10,000 miles. But a proper temperature reading taken at the cylinder head and such you'll find temperatures higher than that. This is also the point at which the combustion of air and fuel is most efficient, resulting in lower exhaust emissions. I would think it'd be the opposite of the cooler was fouled. Most cars run a higher RPMs during colder weather after a cold start. The Subaru CVT is far superior. As an engine rises in RPM the sound produced varies in frequency. When you purchase through links on our site, we may earn an affiliate commission, which supports our community. I guess it would be prudent to check you coolant level as well.
