Been loving my truck for about 4 months now. Went from being a smooth shifter to a "kick in the pants" upshift between 1st and 2nd overnight. Everything else seems fine. I disconnected the battery to reset things and its still a harsh 1/2 shift. Tried Tow haul, no change. Truck only has about 8K KM (5K miles). Guess its off to the service department. Everything I read on the net tells me they are gonna say its normal but the rear end and u-joints not likely to last long.
