My Kanzaki gearbox has a drain. 3GM30F. I know because it cost me a lot of money to have the tranny pulled just so they could helicoil the drain plug that some prior idiot had stripped and "fixed" with goop. That was a very fortunate morning that I decided to check under the engine before a long passage and found a large puddle of clean oil. The drain plug is the hex head at the bottom of the transmission.
