ok so my question if some one could please help!! im putting a le5 into my wifes miata with a automatic trans. I have the e37 harness with the engine but the tcm was front wheel drive auto. I have re wired the tcm harness to the 5l40e as per the pin out on mitchell not a big deal... soo the question now, i am getting a tcm for a 5l40e and being they are separate and really only communicate via can can i just install that tcm and "read entire" and there then should have all the trans settings etc?
thank you if this makes sense to what I'm looking for ?
