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.
