Having said that, imagine the effects of the delay on snow or ice.

If I had to drive this way, it would be in 4low only, to remove TOD from the picture and have the straight mechanical drive engaged.
Where does the tod computer get its wheel speed input from? Maybe I am missing something but, if the VX is moving, with or without a driveshaft all four tires are spinning at the same rate so why would the tod send power to the front? Sounds like it is doing what it is supposed to.
