e40d (~17qts), and the bw 1356 (2qts) both take mercon automatic transmission fluid
I used a synthetic 75w-90 in the the front dana50 (2qts) and the rear ford/sterling 10.25" (about 3 3/4 qts).
An 80w-90 gl-5 is recommended for the rear for anything other than severe use. Castrol hypoy C + a friction modifier meets the ford specs.
For towing or heavy duty use a 75w-140 synthetic is recommended.
My 10.25 is a limited slip, which I think can be particular on what fluid/additives it takes.
The coolant is supposed to be a heavy duty low silicate formula astm 4985 (not 3306), and you need to a sca like DCA4 to prevent cavitation.
I hope this helps and is right.

a dana rear end takes a 90 weight gear oil that meets ford specs of eswm2c105-a whatever that is. It is a ford "premium rear axle lubricant". I think it can use a 80w-90 also if it meets the same spec.
