Auto Transmission Shifting Issues
#46
If I recall correctly, the wording in the TSB specifically said that it was intended to address this issue. That's where I got the term "long soak" from. There's no possible way that Ford can claim they don't know about it. If your dealer is saying that, they need a couple smacks with a cluebat.
OK Ford addressed this issue and I do believe you but I suppose my point is if this issue was resolved, the issue would not exist; unless the intent of addressing this issue was not to resolve it.
I won't blame Ford if they didn't specifically state that the TSB will resolve the issue, probably more of an experiment and safer to not use the word "will" over such a sporadic issue.
If it's resolved on paper and my truck (and others) does this from time-to-time, then it's not resolved within the hardware.
I could care less what's stated on paper.
Anyways...
I don't know what the transmission temp was yesterday because I have the basic screen and I don't know where the transmission gauge was but I'm going to guess half (normal op temp) and I'll explain why I guess normal temp.
I left work at lunch.
I drove 3 miles to Wendys (with a bit of idle) then 12 miles home.
Ate lunch within 15 minutes and was back on the road so none of the hardware had much time to cool down; was 72 or 73 degrees F outside.
This gear skip occured pulling out onto the highway from a side road after another 7 miles of driving.
Yes, most of the previous times I can tell you those were after a cold soak (I'll call that one hour or more due to past experiences). Not the case this time.
After all of that driving, there is no way that transmission was cold.
djjoshuad,
What is the digital transmission temp when your transmission gauge is 1/4 and then at half (normal temp)?
Lack of a fancy screen!

Ive test driven two 2011 Diesel KR's and the first I thought shifted funny, but it wasnt warm. The second did exactily what you are talking about as I was merging into traffic getting off of a highway. I thought I broke the truck... and the sales man joked that if i broke it I'de have to buy it... I got it was a joke and he was a good guy, but its not a cool experiance to have, I was like WTH?!

I think you're a good candidate for a DashDAQ screen... $550 and it gives WAY more info than the productivity screen does. I'm probably going to be ordering one myself .
Can you reproduce your issue reliably? If so, might I recommend some video to take to your ford dealer? I'm planning to do the same thing soon if they do not come up with a fix. I have figured out how to avoid it for now, but I'm worried that it might get worse.

My truck also has a 2-3 shifting issue. If it happens, it is always the first time it shifts from 2nd to 3rd after sitting for a few hours. It will shift out of 2nd, rev up for a second or two, then go into 3rd on its own, I don't need to lift off the throttle. It did scare me the first time it did it. Hopefully Ford can figure it out.

NEW TSB (11-3-23) FOR CEL AND SHIFT ISSUES
<HR style="BACKGROUND-COLOR: #ffffff; COLOR: #ffffff" SIZE=1 itxtvisited="1"><!-- / icon and title --><!-- message -->Hope this is the one that finally fixed the shift issues....
FORD: 2011 F-250, F-350, F-450, F-550
This article supersedes TSB 10-23-9 to add additional calibration content.
ISSUE:
Some 2011 F-Super Duty vehicles equipped with a 6.7L engine and built on or before 3/14/2011 may exhibit malfunction indicator light (MIL) on with diagnostic trouble codes (DTC's) P0401, P0402, P009A if driven at highway speeds with a snow plow attached, P164A if idled for extended periods in colder ambient temperatures, 2-3 transmission shift flares, harsh/inconsistent transmission shifting during transmission fluid warm up and tip-in events when at low speeds or coming to a stop. Refer to the Calibration Content for additional details.
ACTION:
Follow the Service Procedure to correct the concern
SERVICE PROCEDURE
Reprogram the powertrain control module (PCM) and the transmission control module (TCM) to the latest calibration using IDS release 71.05 and higher or 72.01 and higher. This new calibration is not included in the VCM 2011.3 DVD.
The Calibration Update Contains Improvement Actions And Enhancements:
DTC P0401 (exhaust gas recirculation (EGR) flow insufficient detected)
DTC P0402 (exhaust gas recirculation (EGR) flow excessive detected)
DTC P009A (intake air temperature/ambient air temperature correlation) if driven at highway speeds with a snow plow attached
False DTC P164A (O2 sensor positive current trim circuit performance (bank 1, sensor 1)) if idled for extended periods in colder ambient temperature
2-3 transmission shift flares
Harsh/inconsistent transmission shifting during transmission fluid warm up
Improved shift feel for tip-in events when at low speed or coming to a stop
Previously Released Calibration Content
Previously released calibration content included in IDS software release 69.07 and higher contained improvement actions and enhancements to address the following:
Calibration Content Vehicles Built On Or Before 11/5/2010
Delayed manual upshifts from 1st to 2nd gear when in Select Shift mode while going down a grade
Harsh/delayed 1-2 upshift and downshift
Harsh 2-3 upshift on first drive away of day after vehicle soak

Erratic transmission operation after descending grades while in 1st gear
Flashes/delays of current gear indication when using SelectShift mode
Added Brake Over Accelerator (BOA) feature - reduces engine power during off-idle driving when both the accelerator and brake pedals are applied simultaneously
Added SelectShift memory feature, so SelectShift gear display comes back on whenever going back into drive if the vehicle was turned off while SelectShift mode was still activated
Added engine protection feature from overspeed while descending long grades while towing and in manual gear ranges (forces transmission upshifts at 4000 RPM)
Increased torque - during hill assist operation - (see Owner Guide for additional system operation)
PTO operational enhancements - (applicable to vehicles equipped with optional PTO)
- Automatic secondary electronic idle controller (SEIC) turns on at engine start if the switch in on position
- Engine coolant temperature to operate PTO lowered to -7 °C (+20 °F)
- Improved RPM control with SEIC controllers

Thanks for the TSB info.
I would have assumed this TSB was just for the DTC's related to the trucks in colder climates but happy to hear there are transmission calibrations, too.
Because of that I just sent an e-mail to my dealer's diesel service manager to see when he'll be ready to schedule my truck in for the update.

i guess i have been lucky and have not experienced this problem!.. yet. the only thing i have noticed is sometimes it seems like it is trying to decide to shift from 3rd to 4th (rpm change) then doesnt, then decides to. its kind of odd but i think i also experienced it on my old truck. my question is tho, why didnt this 2nd to 3rd shift problem occur to ford when they were testing these trucks before the started selling them???

In their support section, I didn't find anything that does say it is a tuner.
It looks like a nice product if I know plugging it into the OBD2 port doesn't upset Ford and void my warranty since we know this truck logs certain events. I don't have experience with this device so I had to ask.

from what i heard i thought putting any tune on these new trucks voids the warranty?? can anyone else back that up or is this just a rumor??

I know cheezit and Paul discussed this a bit awhile back but IDK if it's know "what" is logged and when a certain event is triggered to keep it in long term storage vs purging unimportant data.
It's safe to say, this truck is logging what we do.
