@VetteDriver First, allow me to welcome you to GM Authority. So, welcome!
Secondly, what you mention is rather intriguing. At this point, I’ve driven two AWD LaCrosses and one Cadillac XTS4 (same vehicle architecture as the LaCrosse), but didn’t pay any particular attention to the shift points of the transmission, probably because it didn’t strike me as being in any way “incorrect”. But that’s not to say that there isn’t something to be improved.
Here’s my question: is the shift point a constant 4,000-5,500 RPM, or does it change based on different vehicle/engine load? So when the throttle isn’t floored, would it shift earlier?
