tranny fluid
So far I've used two redline blends(2qts mtl/ 1qt mt90 and 2qts mt90/1qt mtl) and synchromesh. In terms of shifting feel, the syncromesh is much, much, much better, It eliminated the 2nd gear "crunchy" feeling, and generally made every shift ALOT smoother. I know it's a little thin, but I've been changing the fluid every 5K miles anyway, so hopefully it'll be ok.
