I have a 99 k2500 suburban with a 454/4l80e/246c. I am sick of replacing the transfer case. It's a crappy job on a good day with where I'm working. I happen to have a built 700r4 with a ford pattern (driver side drop) 205. Mechanically, I have no issues with the swap. It's a daily driver and my wife has a light foot. My question is what do I need to do with the engine management system to delete the inputs from the 4l80e? Cheaper the better and hopefully something easier than a standalone ecm. Any help or knowledge would be greatly appreciated.
