Berry just make it down shift at 65-70 mph like you are passing someone. That is where I really sat up and noticed the sound. It was faint but there when I was get on off ramps but man it reaaly stood out when you were passing or jockying for the left lane. Good luck they fixed mine and I have had no issues since..except for the bump/1-2 hard shift. Has never gone away and the surge when sitting at a full stop. Feels like the tranny winds up and then releases. You can feel it pull the brakes and if you are not careful(foot firmly planted on the pedal) you will move forward. Could this now be called unintended acceleration;-) I could easily bump someone in a drive-thru.
Are you flooring it at 65-70? I can't seem to make it do the noise. When it happened before I was flooring it at these speeds, but nothing now.
