I wouldnt do a shift kit per say, but many will say to perform the J.MOD as it's recommended by a ford transmission specialist. I adjusted mine via sct tuner to firm them up, but I would've done the j mod myself if a kit was the only choice.JTAM963 said:EVERYONE tells me to get a shift kit...where can YOU buy one and how is install and all?? I'd rather self install cause labor prices suck bigtime..any HELp???
