Then replace same amount with new Subaru CVTF. JavaScript is disabled. There is a compromise between the lowest gear ratio which improves acceleration and the highest gear ratio which improves fuel economy. The Catalytic Converter which is the main exhaust emissions control device also require a minimum temperature of 300 C before it can operate efficiently. And CVTs also deliver a smoother ride, as it eliminates shocks when changing For a better experience, please enable JavaScript in your browser before proceeding. This is why fuel efficiency is usually higher on a similarly equipped vehicle with a manual transmission. What do you think is it worth it to invest more maintenance into the cvt than Subaru suggests or just have a wait and see approach and hope if something does happen it will occur under warranty?

To spray washer fluid, pull and hold the lever toward you. These are all good product suggestions. I think that could work. 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. Perhaps in technical forum, under engine/drivetrain. Vs a hill climb you spike temps for a short time, possibly only heat up a portion of the fluid in the system, then you have a down hill where you can cool things down pretty quick. I also have a scangauge. If you are accustomed to conventional automatic transmissions, you may equate acceleration with the sound or vibrations from the rise and fall of engine RPM and the shock felt while the transmission upshifts.
