It would be cool to have an automatic shifter but I do not see the need for it.

I doubt a servo would last very long if it were used with our trannies. If it was stalled while the holes were not aligned it might hurt the little motors. The servos would also require very accurate maching methods for the shift rod and also require very good programing to align the shifting rod with the ball bearings.
However a servo could probably handle the job.
