Nope, no warning. If you're doing the fluid at a low mileage anyway, the computer won't really need to adapt to the new fluid. (The old stuff wasn't degraded to the point where the xfer case had to change its programming to cope)

If I waited until 100k+ to do the transfer case fluid, then I'd imagine resetting the adaptations would be necessary.

I don't really remember what I used to do the fluid change now that it's been so long, but I think I used a normal 3/8" drive hex socket on a normal ratchet to do the job. I had the whole transmission sagged down on a floor jack for better access.
