I think you are exaggerating on the harshness of the shift by a bunch. Even at it's worst it isn't near that bad. Yes if you kill the power to the computer it does have to relearn the way you drive. If it suffers from a hard shift you can look to the way it has been driven. If you can't understand the way the computer works then you should take the time to do some online research about how an automobile computer memory operates and figure it out.
