Ok This is a new truck with 660 miles on it and I'm probably just being too anal but...My allison has an odd vibration that it causes when I'm accelerating slowly through approx 35mph and also through 60Mph. Usually it'll only do it as I'm accellerating through those two speeds but for whatever reason I do that often. Anyway, anyone else's tranny do this too?

Edit: It doesn't vibrate that much you passengers probably don't notice. You really have to be paying attention to what the truck is doing to notice.Edited by: WAskier
