Fumoto valve for transmission drain plug?

Hello all,
I am preparing to change the transmission oil in my '08 with 95K miles on her. I dont know if the previous owner did a change on it or not.

My plan is to do a simple drain and fill and repeat that every few hundred miles until i get fresh clean oil coming out. However, i am not looking forward to removing the drain plug that often. I am wondering if anyone has fit a Fumoto valve to their transmission? I heard somewhere that the drain plug for the transmission is the exact same one as the engine oil drain plug. If so, perhaps i can use this Fumoto valve to ease things up quite a bit?

The relevant size for the Nissan Titan is the F103, or the F103N. Wondering if my assumtion that the drain plug is the same as engine drain plug is true?

I would not suggest installing a drain valve on the tranny. Potentially too much to go wrong for a plug that doesn't need to come out very often. When I did mine, the ONE time in 140K that i have (At roughly 110K) I drained, measured, replaced, drove around town 15 mins, drained, measured, replaced, drove a bit, drained, replaced and now the fluid looks new. As a disclaimer, i had a smoking sale on Valvoline max life synthetic locally at the time.

Just seems to me that it's too risky, as the oil drain is on the side of the pan and semi-tucked, but a valve on the tranny would hang straight down, prime for catching something lying in wait to snap it off.
