I wonder if HPTuners can do an overlay for the 80e on the 96 or not. You may have to get the PCM reprogrammed for a 1 ton setup plus doing the wiring harness mods. Not sure how you add the input speed sensor. You could just do a full manual valve body to control the transmission. Are you opposed to installing a floor type shifter and manually shifting each gear change?
is it possible to get a brain and wiring harness from a 3/4 or 1 ton with a 350/4l80e and swap it in? i think i found a 454/4l80e brain and harness from a 97 1 ton. will that work on for my 350?
