I just had my transmission changed on my cobalts as supercharged. Got it back from the shop and it ran great for about 10 minutes then the power steering went out, the clusters flicked on and of twice then died and finally the car started misfiring before finally cutting off. The little anti light came on and now it doesn’t show ip like how you would when to relearn the key or anything it just starts blinking Everytime I try to start the car. Do I have to have a vin relearn for the new transmission that was put in? They car ran perfectly fine before then. So I don’t believe it’s the alternator or battery.
