M920 M916 drop box lube

[Floridianson]

I did not find in what TM's I have for the drop box but I do believe both the cases need to be check. The forward and the main case look like they are on the same level but I'm not certain the oil will migrate from one to another. If someone has the TM showing that we don't need to check both cases for level I would be grateful and if no proof then everyone with a 920 916 should check both cases for proper level.

Ok guess I should have wait till I posted but also just trying to raise my post count.LOL
It does migrate it just takes awhile. ( makes sence). I drained front case and put the plug back in and filled main case and waited 15 min. Then I caught what had filled front case and it showed 1 1/4 cup. So I answered my owen question but I see on serviceing the cases it is better to fill both so that the level is correct in both when done with serviceing the transfer/drop box cases. I believe in filling a case or diff. to where it runs out. Sorry and thanks.
