That’s what I’ve noticed also. While I haven’t taken a 200 transfer case apart yet, I have torn down a 3rd gen Tacoma’s this year which also calls for the transfer case fluid.
I found more brass than any of the older chain driven cases by far. I know GL-5 lubes hate brass which makes me also question using hypoid gear oil in my ‘11.
That and my transfer case never had a problem till I put a GL-5 75-90 oil in it. It would randomly flash “engaging” when going down the highway. Like it was slipping into engagement from speed. Went back to Toyota Transfer case oil, no problems for 40,000 miles.
