it vibrates at 40 then goes away when I speed up. Some people have suggested the transmission shuddder? Hard to figure out any ideas?

I feel a vibration in the steering wheel @ 65 mph. It goes away at 68 mph. I don't "hear" anything, but I can feel it in the wheel. I plan to ask about it at the first oil change.

 

I had the same shudder between 30 and 40 mph. I first took my truck to a Ford Dealer for analysis with 34,000 and was told my warranty had expired based on time. They were not too interested in working with me. Big bucks for repair. I contacted Ford Customer Service to complain and seek help. No problem ! As this is being posted a new transmission is being installed in my ride. All Ford ask is where I wanted to have it repaired. I will, however, pay 20 %, but hey, I can live with that... and soon I will be stylin' down the road............
