Auto will lurch into PRND21
Have a 2006 4.0 with the auto trans at 70K. On the road, the truck shifts well; not Buick smooth, but like other auto cars and trucks that I've driven and I will notice the upshift.
Shifting in and out of any drive gear or Park, I will feel the truck lurch forward moreso than I've had in other autos. I am not sure why this is happening, but I am wondering if this is something I can do to fix it or if there is something I should keep an eye on.
