My insulating cover around the gearbox, drips oil, and the gearbox is on the low side.

I cannot see where the oil comes from, it does not look like there is a leak from the bellhousing so maybe not the shaft seal.?

But to get the recommended oil, Mercon V, seems almost impossible. I have found a Caltex that says Dexron and Mercon compatible, but at astronomical cost.

Went to a local Ford Dealer. They said they drain all autoboxes and fill with William Pynns(?) which clearly states Dexron II.

So, what is one to do, and any fav. spot from where oil might go AWOL?
