I have a edge w/attitude and lately it doesn't matter if I have defuel on or off. It always defuels. The only thing I can think is that the edge is sensing slip and is cutting back the power. Has anyone else had this problem. It drops back so much power it almost stops the truck it seems. Fluid don't look great so I am guessing its slipping. Is there a relearn on the edge I don't know about? Let me know what your thoughts are. I know if your going to play you have to get the tranny done, but the truck has 7,000 miles on it, 1 year old. Have 2 more years of warantee then its play. Let me know, thanks

Mine did the exact same thing , it almost seems like the truck is turning off then back on it sucked.I took it out and put the power pup back in and is way better for driveability.I really would like to run the Edge , but the way it was working it was terrible to drive.
