M923A2 Transmission drain plug thread size

[aziator]

Anyone know what the thread size/pitch is for the Allison transmission drain plug? When I drain it the next time I want to install a Fumoto valve in there to make future services easier. I can measure this time but would rather get one on hand and have it to install. Thanks!

Just to clarify, you looked up the part and the spreadsheet called for a 1" -18? Only reason I ask is another drain valve website says otherwise for a MT654...

Sorry its actually half inch. Copy and pasted the wrong drain plug info.

That oil change valve page says 1-12 for mt654 but i think they add that valve into the drivers side plug that can be used for a dipstick. The regular drain plug is half inch. I honestly would recommend not using the quick drain things simply due to them being torn off either offroad or by road debis. I have had my transmission and transfer case slapped by semi tires.
