With no driveshaft,the vehicle is not moving at the calculated speed that it should be. I am not sure where all the sensors are, but I know there are front and rear. It basis the wheel speed off of the calculated speed based on RPM and gear. At 2000 RPMs, I was not moving, so it transferred power to the front, assuming the rear wheels were spinning out for some reason (rear tires on ice, spinning at 20mph, front tires only spinning at 5mph, therefore shifts power to front)? I don't know what it uses as a reference for the speed.
All I am saying, if the rear tires were on ice, as simulated by removing the drive shaft, I would think the power transfer to the front should be smooth.

I learned to drive in a 1978 volvo wagon, rwd, in Ohio. I prefer RWD cars in the snow, and anticipate the fish tale and prefer to drive based on my own predicted path, not a path that is determined by some computer.
