Shift Flare TSB

My 2011 F250 is just now starting to suffer the Shift flare. On cold Mornings it will shift from 1st to 2nd, back to 1st, then to 4th and 6th. If I take my truck in for the TSB, will I need to return it completely to stock, or can I just retune and retune there at dealership

Unhappy

Any non stock tune could change the shift program and goodbye warranty.

Steps are.

Uninstall H&S ( do not start)
Flash with Ford tune
Re-install H&S

I have done this and it worked fine.

FORD: 2011 F-Super Duty


ISSUE:
Some 2011 F-Super Duty vehicles equipped with 6.7L engines and 6R140 transmission may exhibit a 2-3 shift flare and/or malfunction indicator light (MIL) on with diagnostic trouble code (DTC) P0733 and/or delayed reverse engagement, with a build date on or before 4/11/2011. Symptoms may be more evident or seem worse after an extended soak.

ACTION:
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

Inspect vehicle build date.
If vehicle build date is on or before 11/19/2010, proceed to Step 2
If vehicle build date is between 11/20/2010 and 4/11/2011, solenoid replacement is not necessary, proceed to Step 3.
Replace the three (3) normally high solenoids. Refer to the Workshop Manual (WSM), Section 307-01B. Proceed to Step 3.
Remove solenoids in-vehicle, identify the service band required for LPC, C35R/SSB, C456/SSE solenoids. Do not remove the main control.
Reprogram the powertrain control module (PCM) and the transmission control module (TCM) to the latest calibration using IDS release 73.02 and higher. This new calibration is not included in the VCM 2011.5 DVD. Calibration files may also be obtained at Buy Motorcraft Parts Online | Official Motorcraft Auto Parts Site | FordParts.com.
NOTE: PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS.

Can someone please explain to me what it feels like when you have the 2-3 "flair"? My truck randomly shifts really hard 2-3 and 4-5 it also feels like it sometimes slips from 4-5. I also get funky down shifts at times.

I don't pay attention to the shift indicators until I feel one of these hard shifts so I have no clue if it is shifting up and down and back up. What would this feel like?

Also mine generally shifts fine when I drive it hard (which is rarely). Most of the time the hard or weird shifts happen when driving normally or easy.

The shifts are not related to temperature. They can happen several hours into a trip. They can happen first drive of the day. They can happen the day after a long trip. They can happen out of the blue under normal driving conditions. Sometimes a month or 2 goes by between incidents.

Sometimes it just feels like the truck gets confused. Like after a long trip it has trouble shifting right after getting off the highway and into town. May take a day or 2 to figure things out. This is true for shifting up and for shifting down. But like I said sometimes it happens just around town after miles and miles of the same driving conditions.

I have been in contact with the dealer about this TSB and am supposed to call him again tomorrow to figure out our plan of attack.

Does this sound like what others are experiencing? I know I have posted this question on other threads but never get a real answer of what the "flair" feels like and if my situation sounds like something others are experiencing?

Stock for now.
