If you would have changed the switch to not engaged the front axle it would have split the transmission ask me how I know. Don't blame the truck for a bad driver. I do recommend that everyone undo that switch. We have trucks moving 100,000+ lbs and haven't busted a single transfer case. I have no idea who thought it was a good idea to make these trucks go in to 6x6 when you put it in low, you already have a switch on the dash. The military has come to the idea it is better to make the vehicles do what a driver was trained to know when to do something. I am sorry but I would take a few of 818 and trained drivers than a dozen 931 and the new under trained soldiers to do a job. Now I love all of the military men and women but I believe we are making a mistake in not keeping some of our older style equipment and training to go with it. Proof of this statement is take a 816 and hook it back to back with a 936A2 and have a pull off or a 936 if you think the big motor has a advantage, it won't matter, the 816 will win every time. Don't get me wrong there were improvements the all hydraulic bed and winches, bigger cab, tilt front, and more but the automatic wasn't a improvement for the most part, yeah you can throw a kid off the street in and say go but that doesn't make a trained driver.
