Read you loud and clear on that one...

The All-Knowing Master of Transmissions has spoken and to me this settles it...

You either use Mobil 1 Synthetic or you use a reputable brand that bears the Ford Approved Mercon V label.

An Engineer with a sense of humor. That in itself is hilarious.

(I used to work with a bunch along with a bunch of PhD's.) x3 on Mobil fluids.

I used Castrol last go-around. This time I'll use Castrol Mercon V. Last time around I drained the pan and TC. I see there is a procedure to "pump" out the old fluid. I'll see about following that. But if I don't -- is the Mercon from before and the Mercon V from this time going to be a problem?

I dunno how, but you must have missed the post sandwiched between your two posts asking the same question.

Nah, my first mixture was Castrol Domestic Multi-Vehicle with Castrol Merc V. My 2nd mixture was Castrol Domestic Multi with Motorcraft Merc V. The Motorcraft ATF prices $1/Qt less.

From what Mark is saying -- Merc V from any vendor should be OK.
