Tranny Oil

looking for recommendations on tranny oil for an '85 5-speed. I saw a Haynes manual that spec'd out Mercon Auto Tranny fluid in the T5O-D. Is this right?

Yup, ATF, DO NOT use gear oil as you would in an older 4-speed manual trans. Some people use a synthetic ATF which is fine, that will generally give you a bit smoother shifting.
