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 ???

 

The TCM is located inside the PCM, which is between the left fender and the left battery.

The dead pedal is to keep you from revving the engine while the trans is shifting to reverse.

 

I do not plow snow with mine, but I also have had the same problem when putting the truck in reverse. I have started to just take it easy when going in reverse. If I hit the pedal hard it will shutter sometimes. I think that it is worse when I am pulling a trailer with a skid loader or any significant weight. I'd like to hear anyones opinion on what is causing this.
