Hey mate, I'm running the version of this trans that has the planetary reduction built in. It's pretty much the same base as this and they bolt a 4:1 reduction on the front. They're a really good size, much smaller than tamiya 2 speed, all metal geared. I'm using the wire to shift gears.
Uses a standard 540 can motor, with all the mounting gear included. My trans is the same as the one they use in the Armageddon dump truck. I bought in from a different website tho.
