I've hit 36000 in the WRX and I want to change the tranny fluid and diffrerential fluid. I've looked on that Cobb site with all the oils. I was lookin at gettin Redline MT90 but I read thats its only a GL-4 and Subaru reccomends GL-5.
So what would be a good Transmission fluid, and rear differential fluid? Can I use the same oils for both. And what are the capacitys, for each. Thanks.
