I need to drain/replace the transmission oil on my D19 but not the hydraulic/power director oil. I haven't found clear info on which drain plugs are for the trans oil versus hydraulic oil and it looks like the previous owner put the same oil type in both reservoirs. I found three different drainplugs below the hydraulic and transmission dipsticks, the manual says there are two plugs for the trans:

"...one at bottom and one at bottom L.H side of housing."

I think that means plug A is for the hydraulics and B and C are for the transmission in the photo below. Photo was taken from ground level between the rear wheels, looking up and towards the right front quarter of the tractor

Can anyone steer me in the right direction before I pull the wrong plug and drain a few gallons of the wrong oil?

Doesn't the operators manual clearly state which plugs drain what? Every operators manual I've ever seen does. I don't have one for a D19 as I don't have a D19 tractor. If you don't have an operators manual for your D19, you should have one.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Plug c for transmission and rear differential.

A and B are the the Power Director/PTO gears and hydraulic system. C is for the transmission and "D" is for the differential. "D" is located to the left of the PTO shaft on the rear end of the tractor and forward about 4 inches. Takes the same size wrench as all the other plugs.

Thank you all for the info.

DrAllis, is the same oil is shared by the transmission and rear diff? So I will need to pull both plugs C and D to drain the full 32qt capacity of the transmission?

Update: Found an old answer to this question. Trans/diff share oil and have two plugs to drain. https://www.allischalmers.com/forum/d19-question_topic9082.html" rel="nofollow - https://www.allischalmers.com/forum/d19-question_topic9082.html

When refilling with new oil can I pour everything through the transmission dipstick/breather hole or is there a better spot?

Everything goes in the trans shift cover dipstick, but it takes two drain plugs to remove it all.
