My car grinds gears when i put them in gear sometimes, mostly just 3rd and sometimes 4th.. When the car is cold it doesnt grind at all.. Its a used tranny that had 45k miles on it that i bought from Honda/acura used parts place on the net, they seemed pretty popular so i felt they were reliable...

It sometimes seems hard to put into gear, as well, it wotn grind but it will stop, then go into gear.. I have a exedy clutch with around 10k on it, i havnt done 1 burnout, or dumped the clutch ever. Im not sure if these trannies have em or not, but i was thinking possibly shifter-forks? and if its possibility, how much are those to fix?

BTW ive changed 2 trannies b4, and i did this one myself, did one on another friends integra and it worked fine, so i know im not messing up too much I really hope its not synchro's.. i dont think it is, cause with bad synchros usually u can slide it into gear at a certain RPM and it wont grind, but the way this is now, it will grind at any rpm...

P.S. if i really get on it, comming out of first, and if i put it in second quickly, itll do a quick grind.... It really hurts me to hear that noise, so i take it soo easy on it.. I am open to any suggestions.
Thanks.
