when you hit the little button to the left of the steering column, it turns off TRACTION control, as well as STABILITY control. BUT not the system that gives a LSD feel to the car and transfers power from left to right.

that is ALWAYS ON , unless the ABS fuse is pulled.

so unless im missing something on how to turn off the system that transfers torque/power side to side when one wheel is spinning and the other is not....then when VDC (being traction control and stability control

consider this, when having fun in snow storms with stability and traction control off , how is it that all 4 wheels are spinning? no matter what situation im in? its because its transfering power from wheel to wheel, even with TC and SC OFF ..... without that system because of the open differentials, donuts would not be possible. and we all know thats not the case with 08+
From the FSM:

VDC Warning light and VDC OFF indicator light:

1. Alerts the driver to a vehicle dynamics control (VDC) or TCS fault.
2. Illuminates to tell the driver that the vehicle dynamics control (VDC) AND TCS are inactive. (when system is not failed.)

VDC OFF Switch:

1. Allows the driver to temporarily disengage the VDC
2. In "temporarily disengaged" status, the VCD OFF indicator light illuminates

VDC = Stability control. I'll agree that pressing the button does not disable ABS, but it does disable TCS AND VDC.

Front diff is a plain diff and is not controlled by the ABS system
Center diff is viscous coupling (can act like a LSD) and is not controlled by the ABS system
Rear diff is open and is not controlled by the ABS system
