Computer Question

i wish i had taken a pic of the 545 next to a 727 that i have. i sold the trans a while ago so i cant get a pic for you. but the 727 looks like a toy next to the 545. there have been a few truck guys out there that have removed the trans wireing from the trans and ran an aftermarket controller, and the motor runs just fine (so im told) so you would not have to reconfigure the PCM per se, but you will have trans codes since it cant find the trans. I will let you know how it works out once i get my motor and 727 installed and up and driving. but it could be a year or so before i get to that point.
