with the "low end" shifting of the 2005 automatics? My truck, from a standing start, rolls only about 6 feet and shifts from 1st to 2nd @1500 rpm. I know the Predator can change the "high end" shifts, but what about the "low end"? Further, the shift from 2nd to 3rd also occurs at 1500 rpm and speedo is at only 45 mph. From there to higher speeds the poor engine is lugging a terrible load and unless I go to the carpet with the accelerator pedal, response is poor to non-existent. I am considering a change of the ring and pinion, (from stock to 4.11:1)will this aggravate an already bad situation, or help it? Does anyone know? Thanks.:willy: :confused
