Well since it seems that someone probably wanted to discuss this and never posted; I guess I can post the differences/similarities between this year and last year.

Main Differences:

This year we only have two speeds instead of three.

This year we changed the gear attached to the CIM motor to a 15 tooth instead of a 14 tooth.

Instead of 1/2'' face width gears, we used 3/8'' face width gears for weight reduction.

This year if something goes wrong, which it probably won't, it is much easier to take the transmissions off.

No complex shifting linkages

Last years second gear/speed is gone.

Much lighter.

Similarities:

First gear is still first gear with the exception of changing the 14 tooth CIM motor to the 15 tooth.

Third gear is still third gear with the exception of changing the 14 tooth CIM motor to the 15 tooth.

Still two pneumatic cylinders to shift, but each tranny has its own.

Also not that we changed the gearing between the output shaft and the wheel diameter so that effects our final speed....
