Problems with my tranny.. Maybe help

Well my 2nd to 3rd is getting really really hard to get into gear at high rpms. So i guessing iv got something bent or worn out, but before i rip the tranny out is there any sure way to get an idea of my problem? Maybe something I can do to tell if it is a syncro?

There is not a linkage adjustment for our cars is there?

My car did the same thing with a bad clutch. I don't know if this is your problem, but is a cheaper place to look than the tranny. Mine was also hard on the 3rd to 4th shift.

How can you tell if that is the problem? My clutch only has 6k on it. Anyone else have an opinion?

Don't really know how to diagnose it, except to say shift at a lower RPM.

Having said that, here's where the clutch comes into play. When shifting at high RPMs, the high centrifugal forces prevent the clutch from fulling disengaging; leading to hard or missed shifts. I understand that this is fixed/reduced in many aftermarket clutch setups.

I was told there is no linkage adj. on C5s. I would test the clutch; floor it at low rpms in a high gear, see if it slips; or let out the clutch when sitting in first gear, it should lurch hard and stall. I had a problem with grinding gears, popping out of gear, not going into gears when I first bought my vette. I had to have the tranny rebuilt $1200. Its fine now.

The tranny has never been gone through but, the clutch is a sepc stage 3. My car is putting out 500 rwhp but that paticular clutch is suppost to be good to 500. I cant see why the clutch would be causing me all these problem with less then 6k on it. Maybe im wrong.

I started having these problems after I had a spec 3 put in my car. I broke it in easy for 500 miles and it felt very good. I started rolling into it slowly and had no problems either, but the first time I hit it hard it would not shift. I told the shop and they put a brand new spec 3 in it, they also told me not to go so many miles on the break in. I went about 250 miles hit it hard and the same thing happened when trying to shift. Other than not being able to shift a high rpm's the clutch felt fine, no slipping or anything else. I took it back to the shop and they put a new slave cylinder and a new master cylinder in my car at my expense, but of course the car did the same thing. They put a centerforce clutch in after everything else failed and I have had zero trouble since.

I'm not saying that spec's are bad or that this is happing to your car, this was just my experience. I hope this helps.

One more thing I noticed was that 1st to 2nd and 2nd to 3rd shifted w/o problems but 3rd to 4th and higher seemed to be where I had problems. I am by no means a clutch expert but it seemed to me that it wasn't necessarally the 3rd to 4th shift that was making the problems but the high rpm's for a longer period of time was the culprit.
