When coming to a full stop, the transmission down shift really hard. It makes the vehicle jerk forward. It doesn't matter if you are going up hill/downhill or on a flat road. I took it to the dealer at 4k miles for this reason and was told it was a known chevy issue but that they had no way of fixing it. I took it back a second time at 5k and was told the jerkiness and poop the transmission does is a gm defect design but that they had no way of fixing. Dealer said other owners have installed a 3rd party single piece drive shaft with angle spacers but that was not covered by gm warranty. Dealer essentially wanted me to fix the harsh shifting and clunkiness by going with an after market parts provider. A work around that has seem to make the issue more bearable is putting the truck in �tow mode� it smooths the ride out but it tends to make the transmission run about 20�40 degrees hotter.
