my a33 dun hv snow option. Only auto/power.
when switch to power, 2nd will drag until min 3k before it shift to 3rd gear on slow acceleration. And it change to lower gear more sensitively when you press accelerator a little faster. If you do not used to the behavior, passenger will feels uncomfortable like ridding a mad horse. This option is not advice for beginners.
While in auto, it only shift to lower gear when u 'floor' the accelerator. Hence make the ride more comfortable, and very less aggressive. Also it will shift from 2nd gear to 3rd gear before it reach 3k on slow accelerations.
