Is the rear drive damper in place? Some folks have tossed it but the engineers thought it should be there.

My rear damper is in place, although I had to grind 1/4" off of it to clear the aftermarket rear trans mount.

Made no difference with or without the damper. The issue was there with the stock rear mount and damper untouched as well.

They could of damage the pilot bearing. That TT has to come out. Maybe bent input shaft.

Wouldn't rolling with clutch in test that? Since should no longer be turning clutch and input?

helga203

just because it's a fairly new clutch doesn't mean something happened to it. I know you're fighting but it has to come out. You pretty much did every thing possible.

jrob56

Not my car, just a 3rd party curious. I would suspect with clutch in the vibration/shake should change vs having the clutch engaged, if it was pilot/input, but I could be wrong.

All i did was make a suggestion, the trouble he's having has to do with the drivetrain. What else can it be. He tried a bunch of stuff. But i could be wrong, but i can't think of anything else. I hope i'm wrong and he finds a bolt loose or something easy. Because i would not want to do that job. This is JMO So quit yelling at me.

jrob56

Just conversing with ya, brother, no yelling here.

helga203

no I was just kidding it wasn't directed at you it was a general answer to the audience because every time I voice my opinion against tick people seem to get mad at me. So that's why I say don't yell at me.

Has anyone found the reason for this same exact issue but I did find one of my mounts for the back tailpipe was off and someone said about the headers bouncing into the car didn’t drive it to see if it fixed it yet.

Does it do this with traction control off?

ScottyT01

I have not tried it with traction control on but I assume it would not happen because where it happens is when the cars unusable with traction control I only had it happen 3 times but any time it would spin the tires it did it something I will try today if the rain clears up I have not been able to get out thanks.

A wet road is a good way to easily spin the tires. It may tell you something about this if it doesn't have the issue when the road is wet
.

I didn’t get out until after the rain I could not repeat it with traction control on and 2 times it did it, it was less violent before it was from the dash to shifter box now it seems to be coming only from shifter box and the only mod is a mgw shifter which has only been in the car for a month but I have spun the wheels with it a couple times before this issue came up I did get smooth pavement and spun the tires and it did not do it.

Any new ideas?

Suspension bushing or ball joints. Some play in the suspension somewhere or maybe even the subframe itself. Shocks?

If it feels like wheel hop, it could be wheel hop. Loose suspension will cause it. I am gonna disagree with the rest of this thread I don't think you got a problem in the drivetrain. Sounds like you been top to bottom there three times.

If you can hear or see the problem on video, post it.

Take it to a professional garage. A good place that knows what they're doing. Ask the local corvette club or scca for a recommendation in your area.

This is only good advice if OP wants to find the best wax in the local area.

I'd start some place that has a Dyno, maybe even a machine shop? Basically anywhere drag racing would be prevalent.

I got under the car nothing looked out of line car only has 50k miles on it. I have reached out to come corvettes/ls shops and said they have been bust and would reach out to me but this was like 2-3 months ago so no clue whats going on but one had a dyno when I was reading this the next posts below this was this problem on a c6 and someone mentioned the cv axles and about 3 people said that it fixed it and if you swap sides with them it will change how it feels so I might give that a try but they both look dry and in good condition and no noises are any thing had popped up from them but they did say it only happened during heavy acceleration.

This is some videos I got

I can't tell. Do mean after the shift?
