Grinding sounds from T/C area

[prowirenut]

I just recently installed the EDGE Platinum w/Attitude module. I went through all the set up just like the book says (for once I actually read the directions first). I set the tune to level 1. After driving ~300 miles I heard the most ungodly noise coming from the T/C area, then it went away. The truck would not respond in reverse at first then with some throttle it thumped loud and loped backwards. Then did the same in drive. I drove it and it sounded like it was winding up as I increased speeds. I tried to pull it into 4H just to see and it would not go. The truck is a '06 F-550, 6.0L, 4X4, Steel flat bed with tool boxes, 32,000 miles, no other mods done. Any ideas?

ive heard horror stories of these edge's ruining trannies?

Well I had the Diablo Predator but it didn't seem to do anything but make it smoke a little. I bought the EDGE from a RV dealer that swears by them. I mostly use the truck for pulling my 5th wheel around. The mileage issue I'm about ready to give up on, having 4.88 gears there's not much I can do. I really wish I had my old 7.3 back

Yea, id get it checked out, or maybe someone will chime in. SCT custom tuned is the way of the walk around here for the 6.0. Yea love the 7.3

pull the edge out and see how it works if it fixes it dump the edge

[prowirenut]

Sounds simple enough. That would make 2 different controllers that I have tried and got no results for. What would everyone recommend I buy then? I pull a 38' trailer around 18,000lbs from state to state and use the truck for daily driving in between. I'm averaging 10mpg unloaded. I thought about dropping the 4.88's for a set of 4.55's, any thoughts on that?

Did you ever find out what was making the grinding noise?
