6.7 Tranny Problems (2011-2016)
I recently bought a 2012 F350, 278k miles when I bought it. The first 1500-2000 miles I had no issues. I haul a 36ft horse trailer all over, I need to get to the bottom of this. Truck is tuned and deleted. It is now downshifting HARD 2-1 and sometimes downshifts hard from 4-3 and upshifts hard...
