Torque wars continue in the diesels

I am not certain but I think you guys haven't got a clue what you're talking about as far as how torque management works. When I put my truck in 4 low with a 30,000 lb trailer hooked up and sunk in the mud the amount of torque going to the rear wheels is huge. .. The driveline has to be able to handle full engine torque in 2nd gear while the tranfer case is in high range. My limited understanding of torque management is that the computer backs off fuel delivery during shifts in order to limit high torque on the clutches before they have a chance to fully engage.
