When going through the trans tune, I've noticed different O.s.'s list shift patterns different even on the same platform. I.e. Ctsv's. How do you identify which pattern is Drive, Sport, TuTd, Sport manual? Current Ctsv I'm looking at has Pattern A as Normal, and Pattern B as Trailer...Normal shift is pattern x, pattern A is Y, pattern B is X, tutd auto is x tutd manual is y. Kinda confusing.
