I havent had any problems with it yet but I just put an Edge on it yesterday and from all of my past experiences the increased torque eventually rips them out. My biggest concern is that with the Edge it doesn't increase the line pressure for more firm shifting. I would also like TC lock up ealier than 5th gear. Does anyone know of a programmer to stack with the Edge that will control the tranny. I am completely happy with the power the Edge has so I dont care which stacks make the most power I just want a little more longevity in the tranny not to mention the better fuel economy that goes with locking the converter.
