I should think that there is something wrong with it, You need to take it to a mechanic to investigate the problem.
2,038 corvettes in 1976 had a manual transmission.
'70 corvettes do have a removable crossmember, independent of transmission type. '68 and '69 corvettes have a welded crossmember for manual transmissions and removable crossmember for automatic transmissions.
Low transmission fluid or a bearing is going out.
1000
transmission on 84 -96 corvettes does not have a mount it has a torque arm from rear of trans to front of diff. that supports the load
The transmissions installed in C5 corvettes dose not have a dip stick...
They were in 1978 Corvettes and Chevy Novas, very possibly more
A worn transmission gear can cause a Chevy Impala to whine when the gears change. A bad fan belt can also cause this.
Your throw out bearing is the problem.
A gear meshing whine in your 1996 Oldsmobile can because by low transmission fluid. Check the transmission fluid and make sure it is at the full mark.
Chevrolet makes corvettes.
linkage broken, bad pump, bad transmission. best guess is bad pump or tranny. hope it helps. duboff
