Most of the fast and powerful teams shift these days. It is a necessaty to have a machine that has more than one configuration. The way that the games have a qualifying session and an elimination run, require you to have different strategys to be competitive. Most of the teams who were in the final rounds of the Nationals were bot's with split personality transmissons. To us this extra time and effort seems worth it.

We have been using the Bosch trans for some time now. This year is the first year we decided to shift. We however, decided to shift using servos utilizing the stock housing and shift ring--if anybody watched Team 27 in the pits, they usually saw us constantly going through that silly system! We like the compact size of the planetary system, although they do have more friction than a spur gear style trans.

To avoid the struggle of 2002, 2003 guaruntees we are using a Drag race inspired Air Shifter, also promises a new Aluminum trans housing. A new "Shift Ring" made of steel or brass. A one piece Housing for both the planetary sections and out put. If anyone has seen our trans assembly, then they have seen how we eliminate the clutch. I have all this drawn in AutoCad 14 as a 3D file. If anyone has any questions on how this looks or works I be happy to share some data.
