My 96 z28 lt1 6 speed transmission has been making a vrrring sound going from 1st to 2nd and slightly from 2nd to 3rd. Also has problems going into 2nd gear correctly, feels like it isnt right? took it to shop, they didnt know yet. Anyone have any advice because im not happy....

Thanks

 

maybe the syncros, I just had work done on mine, ahd a loose noise when it was in neutral and had to have all the bearings replaced, it had a similar sound when shifting too, they said it was the syncros. Got it back and it seems to be ok now. Sorry I cannot be of more help.
