Yes - that’s the same on the diffs. You want to do it cold as the oil will expand if it’s hot, but honestly - by the time you drain and fill - it won’t be that hot and your fine.

I personally overfill until it wants to keep coming out of the fill hole and plug it.

drained the transfer case today.. very easy. The fill and drain plugs are positioned well for easy access.

Opened the fill plug, and no fluid poured out. The drained oil had a lot of metal dust particles. I believe this is considered normal for a new transfer case going though break in period

How many miles do you have? I am right at 8k so likely going to do it this weekend. Not shocking there were metal shavings. I have never seen a filter in a transfer case or axle. No pump to push it through the filter.
