I see now. Thankyou. There would be two set of sensors, and they would match rpm of the input shaft to that of the output shaft.

Great system but I see one probem with that. The shift wouldn't be exactly insantaneous, it would wait for shaft speed to = then shift. If a robust enough tranny is built i see no need for the matching of speeds, other than smooth shifting. Ours now is pretty smooth though thanks to the springs on the shifting rod. I have slammed it from 3rd into 1st many times (just to make sure) and it has skidded, I wasn't on carpet all the time, but it could take the throw of the ratio change. I still like both ideas though . / thinks to self/ there is an offseason for a purpose /done thinking/
