I just stumbled across the problems you had with your Astro. It kind of
sounds similar with the problem that I am currently having with my 2003
Astro. When I'm sitting in traffic on an incline and when traffic starts
to move, the truck will jerk when I accelerate going up the hill. At
first I thought the transmission was slipping, but since it has gotten
worse, I can feel the difference between the jerking and shifting. I had
it to the dealer twice and they said it wasn't the transmission, but can't
figure out what the problem is. Does this sound similar to what you have
experienced?
