Hi Cadillac family! My 1993 cadillac sts just started shifting weird. When i start it up and put it into reverse its fine. I start diving and it shifts fine until the check engine light comes on. If i'm already in a gear it will stay in the gear that i'm in. when i stop and start going again it wont shift out of first or second. I have to turn off the car and restart it to get it to shift properly. Like I said it shifts like butter until the check engine light comes on. What could this be?
