Jd 6420
I'm trying to find find the drain plug with the intake screen on my 6420 syncroplus 12-4transmission. The ops manual shows it on the right side. On page 115-3. No. 7. Does anyone know where it is and what it looks like. Thanks

Can you post that page?
My guess is a round plug with an inverted hex. Behind (to rear of) the filter, below the right axle housing.

When standing behind the tractor looking forward, it is just in front of the left axle housing near the bottom. The plug is over 2 inches in diameter and you will need a 7/8" socket to remove it. The plug is made from a type of plastic, so I recommend a 6 point socket.
Actually from the picture I just found, maybe I'm wrong. It looks like it is on the left side in the same area I mentioned. The screen is #7 in picture and plug is #11. On a 6400, the plug to remove is #5.
