Transmission flush or replace

Just curious as my 08 turns 35,000 - flush transmission or complete filter replacement?

You could get away with a flush because your mileage is low but really the best way is to drop the pan and do the filter. If you are doing a lot of stop and go or heavy towing frequently I would say defiantly change the filter with the fluild. Put some new dex 6 in there it works awsome. That's what is in my trans.
