Growing up in an auto shop I have learned some things about how transmissions work, and how gear ratios are figured, and how mechanics in general works. I think that the inital idea of having a sort of screw that connects the powered shaft from one motor is a good idea, but... Let's think how a real automatic transmission works, you have a ring gear, planet gears, and 1 or 2 sun gears. In an automatic transmission in a car there are 2 of these systems connected together to give the car multiple gear ratios. Now you can make a level of the gears, such as the planets stop moving, this gives you a different output gear and a different ratio. What if you could construct a planetary gearset that was somewhat like the one inside of a car. That when you lock one section of the the gearset you get a different ratio, but you can also allow another section of the gearset to spin freely. Thus allowing a drill to be powering the wheels via sun gear, and the whole apparatus rotating around the sun gear from the atwood, and then at a specific point, the atwood powers up, and a clutch of sorts is released and another engaged, and the drill motor is stopped, while the whole shabam is being powered off of the atwood. I'll get a copy of this idea up as soon as I can, I've been working on this concept for some time now.
But that's my two cents on the whole automatic transmission idea.
