Hey guys,

I have a 2012 F-150 SCREW EB and have noticed the past couple days that when it shifts from 2nd to 3rd and back from 3rd to 2nd. The RPMs ramp up on the up shift and I can feel it hard shift both up and down. Is this a concern I should take in and have checked out? This is the first truck I've had off the farm (new truck) so don't know what to expect from the transmission with 3.73 rear end.

 

Welcome to ecoboost ownership my friend.enjoy your stay.

My eb shifts from 6th to 2nd randomly and almost hits redline. It also has hard shifts

 

I had the same issue with my 2011 SCREW. I took it to the dealership and they "Re-Flashed" the tranny and I was good to go.

 

Thanks Biloxi, I'll take it in and see what they do. Here in Oklahoma I'm afraid they'll jump right into removing the transmission and not going the computer route first.

 

I had the "problem" on my 2011 and now on my 2012. They both went for the transmission "reflash" and they both came back the same way as before.

My 2012 is worst and I can feel "hard shift" all the way to 5th gear sometime. On my 2011 it was only 1-2, 2-3... I've been wondering if this could be related to tire size... anybody?

 

I am still having this issue and about to take it into Ford. Anyone have the new TSB done that is supposed to resolve this?

 

Bringing this thread back from the dead I know, but my 2011 5.0 SCREW is doing this occasionally. Id like to know if its something I should be concerned with, or if its normal. I searched around and didn't find too much on this particular issue.

Seems to only happen when the engine/tranny is not up to full operating temp. 1st to 2nd is never an issue, but 2nd to 3rd is sometimes very harsh. Again, only happens when the engine/tranny is not up to full temp.

 

I had the computer reflashed under warranty when I had similar issues. Shifting was 100% improved after.

 

I had that problem with the 5.4 engine. The shifts up were abrupt in 4/5/6, with some of them harsh enough to snap my head back. But it was only when up in the hills (3500+ ft), when climbing moderate grades and traveling at/near the limit (60+). Back down at sea level on coast where I live, everything returned to smooth and normal.

Dealer's diagnosis: Harsh shifting was a result of the differences in oxygen at elevation. Didn't think that would make a difference with fuel injection... If I gave it enough time (i.e. more frequent operation at the higher altitudes instead of just in transit) the truck's computer would adjust to the differences in altitude and things would resume normal ops. Suggested running in tow/haul mode when driving through the mountains (even though not towing or hauling), which has helped. Still notice the occasional harsh shift, but it is better.
