With 13K on it I wouldn't recommend flush unless it was contaminated with coolant. Like I said earlier post, when you can pull the pan and look in there and upwards as much as you can into the valve body and transmission. I suspect it is immaculately clean. If there's signs of water, then that will have to be addressed. If all is clean install filter if equipped, refill the pan with required amount of fluid and drive on.
IMO in general this flushing thing is overused on transmissions/cooling systems when a simple drain and fill will work just fine. Far more room for error when flushing and it is not needed the majority of the time. Flushing should be reserved for very dirty systems where it would take multiple drain and fills to get the fluid clean.
In auto transmissions even if you can't drain the entire fluid capacity in one drain, you can set your drain and fill schedule to keep the fluid in good shape.
