Just got an '06 L59(Flex Fuel) 5.3L out of a rolled Tahoe complete with 4L60e, wiring harness and PCM. I'm not sure it is the correct ECM, how can I determine if it is the proper unit. Also, is this a combo ECM/TCM? Unable to find info on any site............. and yes, it is going into a Studebaker!
