Re: 4L80E sport shift mode

Ok, so what you posted is only selecting how the performance/tow mode is selected by the driver. Not a manual/sport mode. It is telling the pcm if class 2 or manual switches are used to select the secondary shift tables. There is a boolean switch in OS 12587603 that allows for manual shift mode, but I'm not sure if the pcm has actual inputs for manually shifting. That might be for vehicles with TCMs.
