Good luck with your transmission (both in design, and function). In the years that I've been doing this, I have always been involved with the "drive & chassis" in some way. Last year it was by building the transmission, and this year I did design a transmission (and a few variants of it). but a few weeks ago we stumbled across this nice 4 speed automatic, and I'm working up a prototype of that (it had 4 speeds, but I have an idea for adding a high low range). So, the driver can choose between normal range,and a lower range for some more pushing power. It would be similar to a tractor. Giving it in effect, 8 different gear ratio's. Stick with drive and chassis, and keep working on designs. Also, whenever you get the chance to do some of the machining, do it, it's a great thing to know. I myself have been the lead machinist student on the team, as said above last year I build the tranny's, and then I also designed, and built the winch. I go to school for mechanical engineering, but all my free time (what little I have) you can find me in the machine shops.

Good Luck, I look forward to seeing you design come to life.
