Sub’d in this one too.

I was wondering this very thing. I do not know a lot about the lead frame issue but what little I have read about it seemed to indicate that replacement of the lead frame was the solution. I was curious about how Ford was addressing a hardware issue with a software update. I would imagine what you are saying is correct. They obviously are not addressing the potential part failure but are instead modifying how the transmission will respond in the event of the failure (I’m assuming here). It’s the easy way out but personally I’ll take it. I will worry much less about my truck going into neutral or limp mode or whatever else they are going to program it to do than I have been worriying about my truck downshifting to first gear at 70 mph.
