Ok I am going to change all the fluids in my 88 S10. I know that I have to remove the pan to change the transmision filter and the covers to change the Differential fluid. But what about the transfer case? I figure that I just drain and fill but what fluid does it take. Someone said tranny fluid but my old 203NP takes 50wt. Any Ideas.

You need to check an owner's manual or Chilton's for that info. While I don't believe that anyone here would intentionally decieve you, what will happen if you put the wrong fluid in on advice of a GMTC member?

You'll be out a truck, that's all.
