Hello,
Last year, Team 1676 used Ball shifters as seen here:

We had two stage transmissions, and used the standard pancake cylinders to shift from high to low. These were great on the field and relatively easy to maintain, until at Lehigh, and more frequently than not at Monty, we lost air. As most of you using the transmissions probably know, when you loose air, the transmissions shift to neutral; Thus my question: Has anyone come up with a reliable way of inserting springs into the transmission to default either a high or low gear when air is lost? beyond that, has anyone come up with a way to modify the transmission without compromising the structural integrity of the transmission case? Any suggestions?
Thanks,
Let me know
