In that class can a racer use an aftermarket transmission? A buddy of mine runs a Jerico drag race 4 speed in his NSS class....rode with him in the race car once and it looked like he was pulling on the shifter well before shift time but the shifter handle wasn't moving.I don't get how the trans stays together with that kinda shifting... seems smooth though, and i'm betting the preloading is to take out any variation in the shift time, keep it consistent
