while going down the interstate at about 70 in cruise starting down a slight hill, the truck starts making a sound and a jerking like i'm slapping the pedal. It is almost like it is reving the enging. You can feel it jerking like it is not sure if it sould be giving it power or coasting. If it is a big hill it will coast. Once at the bottom everything goes back to normal. Any thoughts?

 

sounds like its comming in and out of TC lockup ???


still new whats the dealer say?

 

i havent brought that up with them? Im in there so much with other stuff they hate to see me walking in.
