want to change the tranny fluid on my truck, but have never been to the dealer to do this...do they have a machine that will extract all the fluid, so then fresh fluid and a new filter can be put in....the other issue is I have a mag hytech pan not the factory and a mopar filter for it already, i would guess that it would not be a problem for them to still do it....anyone have any input on this...thanks Andre...I have always done the service myself, but im only able to get so much of the fluid out....
