I can't figure out what the problem is. When I get on it and the truck shifts, the belt squeals. It really bothers me. I think it has something to do with adding the exhaust and Airraid Intake. After the install of these, the high end shift points went up, and they started to squeal. So far, the dealers say that they can't re-create the situation. I guess they are scared of doing something to it.
Do you guys have any ideas or suggestions?
