The big Av was shifting very hard from 1-2, so I took it into the shop and they said the valve bodies in the tranny were set a little wrong. So I've got to take him in next week to get them changed.
So if anyone else has this prob., it has been confirmed by the Chevy head office that it does exists and you should get it looked at.
