Oil and tranny drain plugs same?

Hi,

I am wondering if anyone happen to know the answer to this? I am wanting to find out if the oil drain plug has the same threading as the transmission drain plug.

I am wanting to invest in the Fumoto valve for the tranny, to make the drain and fill much cleaner and manageable at the intervals. But I need to know what size I should get.

Thanks for looking!
 
I just did both this last weekend - they require different wrenches so I assume they are different threads.

They are the same threading...

I decided to take a closer look today, since I was doing drain and fills for both the engine and transmission.

I was surprised to find that, despite the differing wrench sizes needed to remove each of them, they are both the same threading! Same diameter and everything!

As a result, the Fumoto valve that was going into the engine, now resides in the transmission drain plug. Another Fumoto is going to be ordered to go into the motor oil drain plug.
