I haven't driven it any distance yet. I'm hoping to get it out this afternoon and run it up and down the road to see if I can get it to leak again. I'll keep you posted.

Am I just lucky? I bought my 2005 Yukon XL 5.3L 4L60E Flex Fuel 4X4 new with 4 miles on the odometer b/c it's a Southern Comfort conversion. At 82K, I did have the dealer replace the transmission because when they serviced it there was excessive metal in the pan. I now have 233K on the Yukon, and have never had an engine oil, Trans fluid, or transfer case leak or additional problems with any of those components. I have always done the recommended maintenance on the vehicle.Didn't your mechanic have to drop the Transfer Case in order to replace the back half? If it were me, and I did this, I'd have the TC rebuilt while it was out. Also if I were under that vehicle and saw transmission fluid all over I would have checked the pan bolts. Very common for them to loosen. The end may be near for you with the transmission dipstick though. Once it's replaced it may be good. I'd degrease everything and drive it then look again. Like my Yukon, it's had it's share of problems but once you replace or rebuild everything it's good to go! After all, what is your vehicle but used parts? Another used vehicle (sometimes new one's) can be a whole new can of worms.
hang on to it you got everything fixed nowHere is my saga in short... 2005 Tahoe LT 4x4, 160,000 miles. Last September, transfer case started leaking, pump rub caused it, had transmission guy replace back half of transfer case with new and improved case and new pump guard. All good. 3 weeks later, transmission starts leaking fluid out of the shifter seals. Any time you get over 70 mph, starts leaking, and dripping on the cross pipe causing smoke. Back to the transmission guy to get transmission rebuilt. Got on this forum and got direction on how it should be rebuilt. It took until January to get all the parts and finally get it rebuilt. All good. 3 weeks later, going down the interstate and see smoke in my rear view mirror... What the... Ran by my trusted mechanic, he says transmission is dry, its oil from the oil pan gasket and valley cover. 3 more weeks it sits at his place while he replaces gaskets to stop all of the oil leaks. I get it back yesterday and take off for work 2 hours away this morning. About an hour and 15 into the ride, what do I see out my back window? Smoke rolling off my truck... I pull over and transmission fluid is everywhere! So I limp back home making sure to not go over 60 and stop by my trusted mechanic. He says that the transmission dipstick seal is where it is leaking from. Wouldn't you have replaced that seal when you rebuilt the transmission???
I'm about ready to trade this thing and get a Honda....
Fluid is expelled from the vent tube for two reasons:Ok, finally got to drive it on a 600 mile trip this week. Ran it up and down I-95 and it ran great. Got it up to 83 mph a couple of times just running with traffic. After about an hour of that, I started smoking again (fluid leaking onto exhaust pipe). Just ran it up on the lift and it is definitely coming from the transfer case vent hose. So to recap, the transfer case originally started leaking oil because the pump beat a hole in the case. The transmission guy replaced the back half of the case, and installed a pump saver, that's all. Once he did that, its been one problem after another.
What could cause the transfer case to push fluid out of the vent hose once you reach 80 mph? I drove the rest of the way there and back at 75 and no leaks. Nick, you may know this one...
