Hey guys. I have an 02 ranger 4wd with a 4.0. I am going to be towing my mustang and need it to shift harder, as well as shift harder for just everyday driving. I cant seem to find a shift kit for the E5od tranny it comes with. My next idea was to get some sort of a tuner. That way i could make it shift harder plus remove speed limiter, correct for gear changes etc. Does anyone know what brands offer a tuner for this vehicle and which brand would be best? How much harder would it make it shift, or does anyone know if they DO make a shift kit for this year ranger? thanks a lot!
