OEM transfer case and 6mt fluid change

19 6mt OR here, was just wondering if Toyota changes the transfer case and manual transmission fluid at 30000 miles or not? I'd like to put in redline but I just haven't had the time and would like to make sure I'm not running old fluid. I'm at aprx 39,3xx miles

 

Nevermind, pretty sure I was wrong about everything I said.

 

No I service at same intervals transfer case does a lot of work Im using amzoil in my transfer case it doesn't get that cold here on the washington coast .

 

This is a good time for me to plug my gear oil technical data thread.
