I have a copy of the 2015 Subaru Field Service Manual (FSM) and thier own manual states the operating CVT temperature is between 140-176 degrees F. Most AT fluid is said to lose 50% of it's life for every 20 degrees F above 175F. Others say hot fluid is easy to drain. When I am driving spiritedly I have seen as high as 210 but it quickly dropped down to 205. Subaru Lineartronic Continuously Variable Transmission (CVT), Benefits to Buying A Certified PreOwned Subaru. Driving at slower speed OK. At the range of 45-60 mph, noise is very predominate, thus requiring me to drive at slower speeds than required. Keeping it less than 175F indicates a healthy condition and ensures long mileage. Anything wrong with it will affect the transmissions functions and its lifespan. My understanding is that Forester Wilderness has TR 580 CVT with modified final drive/upgraded cooling and that is not identical to transmission that is in Outback Wilderness.

I suspect the fluid temps between the cvt and the old 5eat will run very similar. This left me with no power on a state highway that had speed limits of 75 mph. Maintaining the ideal transmission temperature is integral to keep it functional for a long time. Due to the linear nature of the CVT, the torque converter is able to partially lock-up at approximately 9 km/h then lock up completely at 24 km/h, and remain locked as the gear ratio changes. 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. I'd like to monitor CVT temp as well. The reduced power output and delay actually delays acceleration, but we have become accustomed to these sensations and equate them with increased acceleration. I was planning on exiting to refuel before this happened. If anything, the company will continue to improve its CVT construction and design and expand upon its application to new models. The steady engine RPM and lack of shift shock are contrary to what you may have been accustomed to and will take some time to adjust to. First off, I called a dozen different Subaru dealerships, and NOBODY could tell me either the temp that turns the light on (too hot) OR, the normal operating temp. This noise does not affect transmission performance, function or reliability. Do some research and you will find that 175 degrees F is an optimal temperature for an automatic transmission to run at.

VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. Of course, cold fluid is also hard on things as well since cold fluid doesn't work as well as operating temperature fluid -- which is the reason for the heat exchanger on the transmission -- as well as oil temperature and pressure sensors found inside of the transmission.

The parts of the gearbox rub against each other and the subsequent friction creates a great amount of internal heat. When the heat reaches nearly 290F, the transmission starts slipping and stop functioning with the burning out of seals and clutches. As we all know, lubricating fluids break down over time and will lose that ability to "keep things slippery". How does the CVT compare to a regular geared transmission? Optimum efficiency seems to be when both are in the 90C range (around 200F). At 260 degrees Fahrenheit, transmission fluid can start to form sludge and clog your engine. The optimal operating temperature for power output, fuel efficiency, and reduced emissions for Boxer Engines ranges from 84 C to 100 C. Still need to find out what the 6MT has as an upper parameter, though it is likely a similar number. Semi-synthetic?

There is a compromise between the lowest gear ratio which improves acceleration and the highest gear ratio which improves fuel economy, in an attempt to keep the engine RPM in this range of efficiency. For vehicles equipped with a conventional automatic transmission upon pressing the accelerator the transmission control module will request a reduction of engine torque from the engine control module before shifting to a lower gear. A traditional automatic transmission has heavy gears with a large contact area. 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. This equates to an effective final drive ratio of 4.03 over the OEM 3.90.
