heres the situation......

old motor - d15b7 new clutch

new motor - d15b - came with new clutch too

anyways i just did the swap
now second gear is grinding at high rpm from first
could it be the new clutch or the tranny

Gunmetalef

syncros?

if you have a new clutch and everything was installed properly then its most likely your syncro's... may as well look for a new tranny rather then replacing them cost wise

I have the exact same problem. My cars at the shop getting a new clutch right now. I'll ask at the shop if its the syncro's. i suspect it is. But ????

if it has a new clutch and the linkage is ok then yes it is your synchro's...nto worth rebuilding jsut find a jdm tranny......a rebuild is very $$$ and nto worth it on a honda...

Gunmetalef

just wondering.. how hard would it be to change syncros and are they expensive? i like to diy and my friend is soon going to pay 1200 for new syncro cuz his fourth gear is ****ed.. he owns a 91 saab 900s i'll do it for him and charge him a bit less if its worth it?

dingus88

dude it is a very hard job...you will need manuals on the tranny and a press and jsut hope you dont' **** up from inexperience...nto for the timid..I took apart a ford 4 speed and it was a dirty bitch...not a novice job...

Well i got my clutch dun and im havin the same problem. My car still grinds from 1st to 2nd too. it sounds as if syncros are a big job. If i buy a used tranny whats to say the syncros are good in that?? how do i know??

d15bvtec

i dont think u can know until you put it on

imported_Turbo-D

someone told me it could be the motor mounts, and or tranny mounts (worn or loose) and or possibly the 1-2 "shift fork" i've never heard of that, anyone know what that is??? let me know. thanks

Gunmetalef

what about the shift fork? there isn't much to wrong? am i right? i think they talking about the fork that engages the clutch where the bearing is hooked up to.. its boletd onto you clutch "shaft" so i dunt see what the problem could be?

dingus88

the shift fork connects to the synchromesh device and slides it up and down to engage different gears...if it is bent then it won't engage the synchromesh and gear correctly causeing a grind...this isnt' as common and a crapped out blocker ring which will cause the gear to not be fully synchronised with the other and grind...

I have the same problem.... I have a new clutch to put in (Centerforce D/F) but I've been holding off till I can fix/replace it.

try changing the MTF, if it works.......there goes 25 bux and your laughing.

i had a slight grind shifting from first to second @ redline.....changing the fluid fixed it. (this was with Honda MTF)

dingus88

to all the guy's wiht grinds...go get this stuff...it is sworn by dsm guy's (they have ****ty grinding trannies) gm synchromesh go get it from a dealership or parts store...it's the best out there
