Don D., on your advice, I filled my bone-dry 727 completely with Mobil 1 ATF. I am very glad to have done so. However, you recommend sythetic Mobil 1 in the trans, but not the engine. Why? I'm sure this is apples and oranges. Does it have to do with the fact that there is no combustion going on in the trans? I also filled my bone-dry power steering pump and box with Mobil 1 ATF. Did I err? Thanks, Sean ---- Please address private mail -- mail of interest to only one person -- directly to that person.
