I use Lucas Oil, but i have heard the GM stuff is just as good!

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?

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

mabye lol good point

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.

thanks for ur post..its my 2nd gear that grinds even thou i shift slow shit grinds sometimes..after i put that royal purple max gear flid 75w90..that shit was not that great..imma try that GM fluid stuff..ill updated it if its any better..

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

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 :cool:

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

hey cjz where in fresno can i get some of this gm synchronmesh. i just put some redline mtl fluid about 1 1/2 months ago but i wanna flush it and try this one see if its really that good.

Lucas oil wins hands down! I looked at there demmo at a booth at hot imports and they had every kind of oil there... It was 3 little wheel's the one on the bottom has a little lever you spin, must of the oils barley got to the second wheel (The oil is traveling upwards on the wheels) Redline and a few others made it to the third wheel like maybe 3 or 4 TRUE synthetic brands... Lucas oil isnt actauly a sinthetic oil at all... LOL, thats the trippy part cause usualy synthetic is lighter and able to move faster and lubricate better and hold heat better (Temp resistance) The lucas oil was spining off the top wheel and splatering on the top of the display! :eek: thats what I'm puttin in next time!

dam i jess change my tranny fluid and put in the GM synchromesh..and that shit hella good...no more grindin on second and i can downshift smoothly to 2nd gear on high RPMs... that shit is awsome...!!u all should use it....DAM
