Rough Shifting 6 Speed? Try this

Well I have 8000 miles on my 12 Eco now and it has been the best vehicle I have ever owned but it has always shifted rough, Mainly into 3rd gear but you could always feel it downshifting when rolling up to a stop sign also, I just assumed it was the way it was suppose to be. This morning I was driving it and noticed it was shifting very nice and smooth, no downshift braking or the other little issues, I also noticed the the select shift was turned off (the numbers on the dash 1-6) if you push the + button on the shifter you can turn them off, I have had it turned on since I bought the truck because I kind of liked the display but anyway with the select shift turned off the transmission shifts very nice, I turned it back on and the rough shifting returned, Try it on yours to see if it changes.

If I understand you correctly (correct me if not), then what you are turning on/off is only the gear (1-6) display. I have mine turned on/off many times and have not noticed a difference in shift behavior. But then, I do not have a rough shift problem, at least not 99% of the time.

Yes, turning off the display also turns off the "Select Shift" program, that is the ability to limit how many of the 6 speeds are used, Mine shifts like it is in the "Tow-Haul" mode all the time but with the select shift off, it shifted very nice, maybe coincidence, I will try it this way for awhile to see.

My truck shifts hard into third gear, as well. All the other gears are smooth as silk. I'm going to try turning off the display. It's worth a try and can't hurt.

Mine went back to it's rough shifting the next morning, at least now I know that there is a issue, I was thinking it was suppose to shift that firm, more then likely a valve body issue.
