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  https://i.imgur.com/UR4y591.jpg 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 |

| 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. |
