Tod relies on input from the propeller shaft sensors in the t-case. Not the abs sensors.
That being said, EVEN if the gem was interpreting slip due to erroneous data from one of the hall sensors, I don't see how that would cause the vehicle to shake. In auto 4wd the front axle disconnect is locked and the tod clutch is energized at ~10%. Accelerating or not, if you are on dry pavement and there actually is no wheelslip, and your tires are the same size* the front and rear axles should be almost exaclty the same speed - increasing the clutch's duty cycle to even 100% should go almost unnoticed in straightline acceleration.
When you switch to a4wd, the solenoids change the vacuum flow around. Maybe there is a vacuum leak in the line to the center disconnect, causing misfire under load. Do you have any trouble codes set?
Have you eliminated your halfshafts as the source of the shaking? In a4wd some torque is always being sent to the front axle.
*Tire size* when talking about the torque on demand system, tire size doesn't only mean the code on the sidewall. To verify tire size you must lift each wheel off of the ground and measure the circumference with a measuring tape. A difference in circumference by even less than 1/4 inch is enough to bring out little gremlins. Two different brands of tire, even though the same "size" can will have a variance in circumference.
