with only 8000 miles, in last week the vehicle has been rough to drive. Thought bad fuel might be a culprit but new fuel and unleaded plus....often shifts roughly in (I am guessing) 2nd gear as I take off...sometimes at 30mph, sometimes 45 mph and even felt like something fell off the car at 70 mph. Everyone in the vehicle notices the bump or shudder when it does so and agrees they have never seen anything like it....I have two others drive the car while I was in it to verify. They all agree there is a problem. In the shop now for reprogramming, but its rough shifting is making me have second thoughts about switching to Ford. BTW, I switched from Toyota to Ford after having rented several Expeditions up in Montana and driving them through various elevations and grades for a week or more each time. Never had a shifting problem. Thoughts?
