I don't think my vehicle was repaired. I brought it in for a very bad vibration and hard shifting in the transmission. I was told it just needed reprogramming and to give it a couple of weeks to "learn our driving habits." Admittedly it has not been 2 weeks since the "repair" but it still vibrates badly and shifts even harder than previously. It almost feels like, at times, the transmission is going to fall out of the truck.
