Hi all, I test drove a car and it drove perfectly, but a mechanic inspected it and the battery was dying. After the dealer put in a new battery and I purchased the car, the car was experiencing some hard shifts. I found this relearn process for after installing a new battery for the F150 here, and it seemed to have solved the problem for me as well. I drove the car for about 10 miles and all is well now. Has anyone had experiences with this?
