My syncros hate me.

[Polygon]

I was headed to work yesterday and at the light before the freeway entrance an Infinity FX45 pulls up in the right lane. I knew he needed in my lane and was going to gun it. When the light turned I let her rip. However, when I tried to get into second it wouldn't go. It would just sit there and grind until the RPMs dropped enough.

So I made two mistakes. I didn't launch the car and I have crappy syncros. Needless to say I'm bummed that the Stealth has a death on it now.

Only one problem, I don't know where to get a full set of syncros. Otherwise I would have done it by now. I've known the syncros had issues since I bought the car. I can only seem to find 1st and 2nd gear syncros from Kormex. Someone on 3SI was going to do a GB for some hardened syncros but that seems to not be going anywhere.

why are you only finding 1st and 2nd at kormex? i got all exept 4th when i got mine done. did you call em?

alright, lets get some things straight. there is NOT a synchro for every gear. a synchro allows for a smooth transition BETWEEN gears, but there is not a synchro between every gear. there are synchros for the 1/2 gear change, 3/4 gear change, and if you have a 5 spd, there is a 5/R synchro. or if you have a 6 spd, there is a 5/6 synchro, but no synchro for R in the 6spd.

so the synchros you need to find are:

-1/2 synchro
-3/4 synchro

usually the synchros for the higher gears last longer than the lower gears.

So, you mean to tell me there is no syncro for the 2-3 gear change?

Like I said before, problems are like modifications on a 3/s, almost everyone has a few.

Well, it shifts smooth as butter if I drive normal so I may be lucky and it might not be a syncro. I'm hoping a mix of Royal Purple Syncromax and 75w85 will fix the problem. However, when I shift from 2nd to 3rd, even when driving normal, sometimes it grinds.

[jason_bet]

so you need the 3/4 syncro.. and lineback there is a syncro for every gear there is a syncro on each shift fork.. 1/2 use one sift fork 3/4 use one shift fork and 5/6 use a different shift fork..
so when you shift into third you are changing shift forks and useing the syncro that is between 3/4 gear

Ahh, I see.

I'll admit, I don't know a great deal about manual transmissions. Nice to learn something new. So, the problem being that Kormex only has the 1/2 and they don't have the 3/4.

its the blocking rings you need anyway

i got 1,2,3,5 gear blocking rings installed and grind gone...and never came back.

so maybe you need to call them and see if they have blocking rings



i just called em, and they have em for all gears.....its the blocking rings that go bad that causes the slip/grind you hear
there $80 a piece

Hate to say it but I'm starting to have problems with my 1st to 2nd shift at high rpms...which certainly hasn't helped in some recent races. Namely a Porsche 911 that I was having some fun with on I-95

[Boosted1]

Most people seem to have problems with the blocking rings like mentioned above. Just a thought - I bought a blocking ring from Kormex (1/2 grinding), spent almost $500 to have it torn apart and replaced, and it did absolutely nothing. You may want to have it diagnosed just in case...

I'm going to try changing the fluid as a first step to see if that solves the problem. If not I'll go from there.

[jason_bet]

if not.. i would say pull the tranny and bring in to me at the dealership.. grant has done a few and is good with the 5 speed tranny
