Larry,
I did a search on the Ritter/Easley list re: ATF and blower motor bearings and indeed there are numerous references to using a few drops of ATF on both bearings. These are mostly from Marshall Booth, a frequent contributor to that list, and the diesel technical advisor for the STAR. You could probably email him directly (I think his email is usually listed in the STAR) if you want more info on his experience.
