Manually shift it exclusively for 200 miles of mixed driving and you'll find that the automatic shifts in D should mirror you pretty closely. I also have a manumatic Sebring Ltd Conv with similar adaptive logic and found that trained the TCU pretty well to my driving style. It's not going to compensate for a mechanical issue but it does make things more agreeable. The only TCU training headache I've found in my short SRT ownership is that it initially defaults back to "D" too quickly. That too seems to improve with training though I do wish they incorporated a separate manual mode in the shift gate like most of the manumatics. Even the Sebring with all of it's 200hp has a separate manual mode.
