This comment is interesting, as I've been thinking of shifter throw in terms of a longer or shorter wrench.
I would expect that the longer throw of, for example the OEM shifter, would give the driver a leverage advantage and for the same pressure applied to the shifter ball a larger force would be applied to the internal bits of the transmission.
By shortening the throw it would now seem to give the driver a leverage disadvantage and therefore for the same pressure applied to the shifter ball, the applied forces internally to the transmission would be less?
Most cars I've added shortened throw shifters to end up requiring a bit more lever effort as a trade off, hence my long vs. short wrench leverage analogy. At some point making the throw overly short would possibly make the shift effort unacceptable.
What about the shorter shift throw increases stresses on the transmission? I've been thinking in reverse about shifter throw and taking some solace that I was not hurting my transmission. The engineer in me just wants to understand.
Thanks
The reason the shorter throw puts more stress is because you are making the shift faster and thus the synchros have to spool up faster and when they do not you grinnnnndddddddddd
This is why the gt500 cars started having 2nd gear grind issues when ford came out with the svt perf. pack shifters which was basically the kr shifter. the throw front to back was too short. it really has nothing to do with the actual leverage or force. that doesnt matter so much as how fast you articulate the lever and try to make a shift.
