Do you know if there is any physical difference in the transmissions (with the IVT or the CVT) to go to 60kph or is it just the programming? My 6420 only goes 26 mph and I took a long shot and asked my dealer if the transmission could be flashed with newer programming to allow 31 mph and of course they said it couldn't be done.
