Someone know where this TCM is located,,,now and then while plowing snow with my 06' F-350 6L. TS auto,,when I come to a stop,,lift the plow, put in reverse,, I get this shutter like the tranny is slipping, truck shakes like tires are spinning,,but there not,,and there is also a slight dead pedal, like 1-2 seconds when this happens,,only does it ocassionally,,I have just eased up on the go pedal when putting in reverse, when I feel this starting to happen and seems OK,,but still an issue. It's like when lifting the plow,,the draw on the electrical system, makes the tranny slip,,but only once in a while,,,any thoughts if the TCM could be doing this ???
