My credo
"I'm not Mr. Lebowski, YOU'RE Mr. Lebowski. I'm The Dude."
FYI.
My '08 Trac will hit 150k this week and I've changed the t-case lube every 30k since new. Also previously on a Ranger and another Trac that I didn't keep as long. Here is what I've learned. If you look carefully the manual will tell you to change it every 60k. However if you drain it at 30k you will see that it looks like tar. This is probably due to breaking in from new because at 60k it looks better and by 90k it drains out pink. Today at 150k it drained out clean with some fine metal filings in it which is normal. My recommendation would be to change it at 30k (we're all probably way past that), again at 60k, then every 60k after. I have used Mobil 1 ATF, Redline D4, and the last two times Valvoline Synpower Transfer Case Lube.
