One bit of advise, one very knowledgeable transmission person cautioned me that some definition files have mistakes. A lot if this stuff is reverse engineered with a big fat guess. So what you think you are changing might not be what the computer sees or likes. I tried a few pretty wild trans changes pushed by "experts" on the forum then when the trans started doing some weird stuff, I went back to factory programming with just the minimal changes I needed. The results were a lot better.
