Best Mercon V

[T-Flip]

Trans flush and rear diff are next.. Can anyone recommend a good Mercon V? I'm looking at a few options right now:

Motorcraft
Castrol Transmax
Supertech

Which of these are full synthetic, and is running it any better? I am staying away from Valvoline because I cannot get clear information on their mercon v licensing and compatibility.

Anything certified as Mercon V, must be full synthetic.

I believe mercon v specs require it to be a synthetic blend, I have yet to find a full synthetic mercon v besides mobil 1 atf. Maybe I'm overthinking it, maybe it's all marketing & semantics.

What do you use in your transmission joe?

Can't go wrong when you use the Motorcraft Mercon V considering that was what was used in it from the factory.

Motorcraft... at recommended change intervals.

Mobil One Mercon, (not 5), was a good choice for my 95 F150... for 175k of its 225k miles... but for the money... and a deep pan (17 quarts total), is very expensive.
