I have a t56(out of a 94 z 28) behind my chevy 350 and in nuetral iam getting a vibration from about 3700rpm on up.The engine has been balanced the clutch set up has been balanced. So what could be going on in the trans that would give me vibration? I have heard that pulling a t56 apart is a little tricky cause the case can twist. Is that so??? I pulled the trans and put a new pilot bushing (bearing type) some people said that might help but it didn't. I do notice that in 5th and 6th I feel some vibration also.
