25 series common transmission/differential sump?

[vhacmoduprej]

Does the 3325/3525 have a common sump for transmission and differential? I'm assuming both drains are for the same reservoir? (no service manual yet)

I have a 3525, and a service manual. Yes, the trans and differential share lubricant. Both plugs drain the same housing, one in front and one in rear. Oil specs call for API GL-4, and specifically warns against using GL-5 as the transmission has copper based alloy components which can be corroded by GL-5.
