I am running stock gears on my F250 With a set of 35/12.50 on it
I am Rigging it up to pull a 37` fithweel.
All of the charts I find on the net are for a stanard trans.
Mine is a auto with overdrive, the towing I will be doing will be
in the south (flat land)and in the north (Big hills) I NEED SOME HELP

Thanks
