I'm having the same problem between 25-38 miles per hour a heavy vibration is occurring. The dealer is going to look at this for me next week. I'm told it may be a transmission issue.

I had this same issue. It turned out that the transmission converter was damaged (this was causing the vibration). However, they had to fix the whole transition since they found metal particles in the system and the transmission was failing at the 3rd and 4th shift, and therefore simply changing the converter would not work - $1,600 for the whole thing.
