Hi all im a new here and im sure there is a post here somewhere about this but i had no luck finding one with exactly what mine does. Ok so the car lot just replaced the 5 speed transmission in my 05 Cobalt SS it has the limited slip tranny. So when im driving it nice and easy its fine, But if i jump on it and then try to down shift or anything after im done (and not a t a high rate of speed) Say Your messing around and then there is a red light so you start slowing down but before coming to a full stop the light changes it wont go into any gear unless i stop and put it in first then its fine. Im so confused ive never had anything like this happen before and ive been driving a 5 speed since i started driving 20 years ago. Anyone have any ideas of what it could be??
