I just read the article last night, Joel. Indeed the LBSS (Load Based Scheduled Shift) reference is in a separate article box, so it was an addendum that FMCoaching editors and Allison added to the print version; you should check your paper copy.
If the LBSS is an available upgrade, I personally wouldn't pay a whole lot for it, because I drive like Brett suggests, and find little inconvenience to the relatively rare need to shift out of Economy Mode. I like to think I'm a pro-active driver, and afterall how much effort does it take to move a finger over to the Mode button?
I guess if one doesn't want to fret about when precisely to make that move, such a feature as LBSS may be worth some cash outlay. I just enjoy the challenge of understanding the system I'm in control of, and applying my own decisions accordingly. But others may not view such decisions or challenges as fun; or if contrary to Brett's recommendation, one has been in the habit of constantly shifting between modes, paying for an LBSS software update may seem quite palatable.
A call or email to Allison customer service or local service center might prove enlightening.
