So your jeep still has a "transfer case" it's just built into a transaxle mounted directly to the engine. If you look on the video the front drive shafts come directly from the transaxle as does the "prop shaft" as he calls it.
I'm impressed to see its a 9 speed. I'd like to see the 2500's 250's come with 9 or 12 speeds. Weighted at the bottom for torq and at the top for highway miledge. I saw a you tube vid once of a f350 the guy had remade the bell housing on a freight liner 16 or 18s it wa pretty sweet. Mind you he did a no throttle take off from a stop in 4th if I recall. Maybe for most uses around here that's a little low. I'm willing to bet he's not got much more top end than the stock was.
