Default 2012 TSB for tranny
Does anybody know if there is a TSB to reflash the computer for a harsh shift. Mine shifts perfect in every other gear but it will slam like a bitch shifting from 2 to 3. My truck has near 5000 miles on it and the dealer reflashed it at 2000 miles and it was great for 300 miles and then it started to wig out again. It will not shift hard all the time but at least a third of the time. I wonder how the hell a tranny can be so good on all other shifts but the 2nd to 3rd. Any ideas from some of the Ford techs.

Mine does the same on light throttle. I updated it again last weekend since they had a new update in May for some other drivability concerns, its better so far but I'm sure it will come back

Mine does too. I found that I can avoid it by using a little more throttle when accelerating.

Yea that is pretty normal. Mine does the same thing.

So there was a new Pcm update in may for the 2012? How do I find out when the updates are and what changed in them?

What was your build date, or if you have had it updated when was it done? I'll try and copy/paste the tsb here later

I just had TSB 12-2-16 performed on my 2011 5.0 2WD Screw. It not only took care of the shifting problem, but my chronic/consistent 15.5MPG City & HWY, went to 17.5/20.1.
