With all due respects, Jim, I don't see any reason for me to use anything except what is recommended by the sources quoted in the last three posts, and when the Chevrolet S-10 Handbook states that the product to use is ATF, my question is answered.
I just thought I would run the question by one more time because I was considering a change to oil, but I don't want to damage my T-5.
Thanks, everybody!
