GM Synchromesh manual transmission fluid??!!

[nismo831]

I recently finished my 5speed swap, bought a transmission with 130k miles on it a little over a year ago. The transmission grinds every time I shift into 3rd... Did a little research and many people say that the GM synchromesh will solve the gear grinding problem, has anyone ever tried this transmission oil can it be used on my z32??

I cant say that I have used the GM Synchromesh, but I and many others on here have used Redline Mt-90 and it got rid of pretty much all my grinding during shifting.

i am currently using gm syncromesh in my z and its shifting nice and smoothly and can say its been going very well for over a year now,i have used redline mt90 in my old s13,its was night and day from whatever fluid was in it before,it was like silk.
i plan on going mt90 in the z when i change out my clutch in the near future
