The interchange list that aleekat posted didn't fit my 94 S10. Here's the one I had to use.
1992 - 1994 Chevy S10 1992 - 1994 GMC Jimmy 1992 - 1993 GMC Sonoma.
I got a TCCM off of ebay from a 1992 GMC jimmy for $35 bucks and it fixed my 4wd. Thanks for all the help. I would have never figured it out without it.
