I'd like some input on an issue I'm having. Recently while cruising at high speeds I noticed a bad grinding noise that seems to come from the trans when you push the throttle and let off. The faster you're going to the louder and longer the grinding happens. Under 30mph you can barely hear it at all. The truck drives fine and shifts fine. My U-joints are tight and i only noticed it when I was on the highway and now I notice it all the time.
