I've been having trouble with my Sy the past few weeks and I don't really know what it is, hoping someone could shed some light. I was having shifting issues that would keep getting worse and worse till I topped off with tranny fluid, there's a leak somewhere. But at highway speeds the truck surges, around 50-65mph. And it surges bad, making the whole truck shake. The truck only has 41K miles so I'm hoping the tranny isn't gone already. My only other thought would be the TC?
