I've got a 93 trans am with a 4L60 in it. It was rebuilt right before I got it. I was driving it and all of a sudden no second gear. Every other gear works I'm wondering if I have a bad solinoid? Just wondering if anyone else has had this happen? If not I'll build it,but my question is its basically a 700r4 so will I just order a 700R4 kit? I'm also getting ready to came the car so its going to have to come out for a stall converter anyway. Sorry for all the the questions seems like my car is a bastard child being a 93.
