Transfer Case

[Suprawill1]

Hi All,
Is this ok for our ST's transfer case? It's full synthetic and is supposed to meet Ford's transfer case specifications. .
Some say use Mercon LV transmission fluid. I believe it's 1.1qt to fill.

Also, what about the front and rear diff? One guy quoted me $480 to drain and fill all three cases.

I use Mercon LV in t-case. For diffs, many run 80-140 in both front and rear even though they spec 80-90 in the rear. Any full synthetic is fine. It’s not too bad so long as the have a thin 3/8 drive tool. Front is easy. Val line squeeze pacs make it easier too. Not much fluid in either diff so I change every 30k or so.

I used AMSOIL. And that price is too high. IMO
