I have an 86 Z28 automatic and have noticed at around 45 MPH it shifts up and down. Like it can't decide which gear to go into. I have noticed it before but it seems to be getting worse. I had the transmission rebuilt about a year ago (along with an new engine 2 years ago). Can someone help me out.

Thanks

86rebuild, If I was you, I would take it to the shop that did the work and see if they can check it out for you, it is hunting and maybe a TV cable adjustment will take care of it.
