For the past few months sometimes when I go to start my truck up the truck will lunge forward after you start it up. I don't understand why it's doing this especially if it's in park!! Has anybody who has the 10 speed transmission experienced this. It does this like 1 out of every 10 starts. And it also does it when your driving around and come to stop sometimes you will hear a thud and the truck will move a little bit.
