If all the components are functional and you are driving at a normal speed, the ideal transmission temperature is 175F or less. The fluid churns inside the torque converter, gears, bearings, clutch plates, and other parts and its temperature increases with the car in motion.

This started to occur after I had the valve spring recall taken care of. Starting in May 2009, TR690 has been used in Subaru Outback 2.5 l models. When decelerating over a longer distance such as a highway off ramp the CVT will keep the torque converter locked-up as long as possible to provide engine braking similar to a manual transmission equipped vehicle. An ideal transmission would have a very low first gear ratio and a very high final gear ratio. 1) Its a CVT not a trans with clutch packs, different animal and hard to make a direct comparison between the two without a lot more background knowledge and data. nickypooh Registered Also, its not causing any issues as far as decreasing performance of the CVT unit in efficiency or power delivery long term.
