yea, i can't really back it up, but i have heard the same as the 2 above. that its really the best stuff to put in our tranny

i had problems with my 3rd gear grinding i used redling mtl, didn't do nothing at first but 2 days later no more grind in any gear. really helped.

lol i have no clue wtf ur talking about but all i know is when i shift really fast i grind going into 3rd but when i hold the clutch in for like a sec then shift slow i don;t grind how could i fix that?

[FourthGenHatch]

Usually grinding is the drivers fault, hand too slow for the fast foot.

[blueturtle]

mabye lol good point

[Redline_civic91]

not really. third gear is usually the first gear to go out in honda trannies if it grinds every time than your tranny might be going out. you should try redline mtl tranny fluid or that gm whichever u want, both are very good. if that dont work your gonna have to take it in to fix the synchros.

Thats because GM syncromesh is for AT trannies, not manuals Who put that in there?

[Fishcat37]

I'm running GM Syncromesh in my Y1. It substantially cutback on the amount of grinding that I got into 2nd and 3rd. It's $17/quart and worth every penny of it imho

[seth 90DX/ZC]

Hrm... Realy? I was told by my teacher in auto shop not to use syncromesh in manuals... ?

Ok there is a guy in my town that rebuilds honda trannys he always uses GM sychromesh Fuild. He also will warrenty the trannie for 25,000 miles is you use GM fluid. So my thought is if he is warrenting them for 25,000 miles there must be something he knows cause it would cost him a buttload if all these trannys came back cause they where bad from using the fuild.

Oh ya since the second week Of owning my civic I have used this fluid It was grinding before but about 2 days after I put in the GM fluid it doent grind anymore from 1st - 2nd Just my 2centz
