Fluid quantities for 78A D4D....

Thank you so much for the information!! I pulled the two main plugs on the center of the body ( clutch and transmission ) I assume and drained over 20 gallons. When I bought it I noticed that every dipstick showed over full. I ran it only enough to unload it and then drained everything. The engine was only about a gallon over and it appears that it did not hurt anything but wow did they have the transmission over full. I only got about 1.5 gallons from the hydraulic system, so that one was low. Guess we will fill things back up and see what happens! Thank you again!!
