Anybody try using GM Synchromesh in their tranny? Yay or nay?

 

Meh.

I tried it when I had bad synchros it helped marginally, as in still I would still grind but not as easily. I've since switched to Honda MTF (after replacing synchros). It did stop all grinding on a different tranny though.

However that is not to say that a fresh flush with Honda MTF would not have accomplished the same thing.

 

I know a couple of guys using it. They claim it has worked wonders with some of their grinding issues. Another local guy used in his FD3s and swears by the stuff.

I too would like to hear about others experiences with the Synchromesh.

 

I run it it seems to work.

 

Smoother shifting than Honda MTF?

I've never used anything but Honda MTF in my tranny. I will try it out next summer.

Honda MTF for winter
GM Synchromesh for summer
