I believe the only changes involved were to the ecm/harness to accommodate the extra switches and the up/down shift function. The P700 is realluy just what honda started with back in 2003 on the TRX680 Rincon, full auto and electric shift modes. They just had to add the small engine cut out to be able to shift without lifting the off the throttle. The basic engine design hasn't changed, I also don't think the converter has a lockup function either. It serves the same function as a centrifugal clutch in this engine type.
