i started using mt90, before that i used the cheap shit too, i think the trans feels better with the mt90, but it might just be the fact it’s an rb25 trans and not the punny sr/ka/ca/rb20 trans
Ted, I also use redline and it DEFIANTLY makes a huge difference over a cheaper fluid. First thing I’ve done with a few KA/SR tranny’s is change over to redline fluid. A world of difference in shifting.
Daily driving probably not a huge difference, but if you plan on tracking the car and really beating on the tranny and getting it hot then put some good fluid in. Unless of course tranny swaps are a huge turn on for you.
