A lot of people seem to be swearing by Synchromesh. Is it any better than Redline? Mine is still notchy after having a fresh change with Honda fluid, although not as bad as it was before.

 

IMO RL MTL is too light for the S2000, but I was very happy with RL MT90 during the summer. MT90 will probably feel too heavy in temps below ~40F but I think it is the best of all for temps over 90F.

 

I used Redline MTL once and loved the way it felt initially. The transmission seemed to have a smoother feel when rowing through the gears. After 10k miles, shifting into each gear seemed to be getting harder and harder. It's like it didn't want to get into any gear with ease. It got progressive worse until I switched back to the Honda MTL

Since then, I've stuck with the Honda MTL and haven't thought about changing brands until all these GM Synchromesh threads popped up.

Since I put about 3k miles a month, I'll probably change soon to see if the GM Synchromesh can stand the Houston traffic torture test.
