Prior to the 5,000 mile oil change, I experienced at least five transmission shifting issues and reported the problem to Bergstrom Service Department. They test drove it and found no issues at that time and could not repeat the shifting issues while I was there. From what I have observed, the engine will rev up to a high rpm but will not shift automatically. You then have to pull over to the shoulder of the road and decelerate the engine until it will shift gears properly at a slower speed. Not only is there a flaw in the transmission but there is a safety concern when accelerating from a stop sign or merging onto a freeway. I fear getting into an automobile rear end accident from a transmission malfunction. Since the 5,000 mile service, we have experienced one more engine rev shifting issue.
