ok so you meant you dont know of any simple plug and play TCM solutions that exist for the rfe.a harness does not give you the ability to control the transmission and drive the truck. a harness gives you the ability to plug the harness into the transmission and tcu. you need a proper calibration in the tcu in order for it to control the transmission. yes you can order the tcu and yes you can order the harness and you can plug it in, but it will not operate the transmission without the proper calibration loaded into it.
There are TCMs, but they need to be programmed. Cool. That doesnt scare me. I can pay for anything I cant do myself.
no wife, no kids, no mortgage, good job.
I expect challenges, wouldnt be doing this otherwise.
