![]() ![]() Certain non-OEM oil brands did develop CVT transmission fluids that do well in all types of CVT transmissions but we still recommend only using fluids that are approved by the manufacturer of your car or transmission. Each CVT transmission requires a specific CVT transmission fluid with correct viscosity and other qualities that assure correct and precise transmission operation. No, all CVT transmission fluids are definitely not the same. If you extract a sample of CVT fluid from your CVT and it is completely black without any transparency or color, it means that your gearbox fluid is heavily contaminated and in need of a replacement. Ideally, CVT transmission fluid should always be semi-transparent with a shade of the original color (red, gold, green, etc.). Any fresh transmission fluid is almost transparent with a certain color. CVT fluid is only colored so that the mechanic or yourself can visually determine the level or CVT transmission fluid contamination. For example Nissan CVT gearbox fluid is brown/gold, Valvoline CVT fluid uses a shade of green but most CVT gearbox fluids are actually red. What Color Is CVT Transmission Fluid?ĭifferent CVT transmission fluids come in different colors. CVT gearbox fluid is different from regular automatic transmission fluid (ATF) but just like ATF, CVT gearbox fluid needs to be regularly replaced. Every CVT transmission features an oil pump that keeps the circulation of CVT fluid going and a filtering system that usually also features magnets that catches all the contaminants which can be harmful. By doing so it keeps all the moving parts lubricated and cool at the same time. Those plugs can get frozen solid in those aluminum casings, and if you drain it and are unable to remove the fill plug, you are all the way up the creek.CVT transmission fluid is essential oil or lubricant whose job it is to circle the CVT transmission. Oh, and one more thing - if you do decide to do it yourself somehow, when you do the rear diff, make sure you back out the fill plug on top of the differential before you remove the drain plug at the bottom. If you can't do it yourself, I'd stick with a shop that you know to be reliable. Many Subarus - and I don't know for sure if the 2007 Impreza is one - have oil pans that look very, very much like the transmission pan, and there've been a lot of horror stories about careless mechanics who drain the oil and then add a gallon of tranny fluid to the automatic transmission. If you can't do it yourself, I'd make sure it's done by someone you really, really trust. Ordinarily, this is where I'd probably suggest to someone that they just find a backyard mechanic on Craigslist who'll do it for 50 bucks labor or whatever - but I wouldn't recommend that in this case. That can make it a little more complicated. I would try and do it myself but I live in an apartment complex and they don't want people working on their cars. It's an automatic and I did get a quote at another shop for $350 included trans filter. ![]() Faithful drain-and-fills will keep that tranny running clean and smooth for another 140. As some other posters have said, with that many miles on the tranny, there's bound to be a lot of metallic crud in the fluid that will get stirred up and recirculated in the transmission. Drain whatever's in the pan, and then replace it. With that many miles, you should just stick to drain-and-fills. ![]() But you certainly can't go wrong with the Subaru fluid.ġ40,000 miles? Definitely don't flush it, then. Not a lot, but it's worth it to me because I go through a gallon and a half a year. It's the same specs, and usually a little cheaper than the Subaru OEM. If you do decide to do it yourself, or at least buy the fluid yourself, you can save some money by using Idemitsu HP ATF. They wind up replacing their transmissions. Yes, and thank god you're an owner who takes that recommendation seriously. Yes, after taking it in they said Subaru's require a certain special type of fluid and it would be a little more than usual. ![]()
