arggggg Dredded P0756

[Sholab1]

Well day went into the toilet . come home from Rome NY, something was acting up. Steppen on the gas on the on ramp and car seemed to miss a gear. it finally caught and seemed fine, went into Ontario service center to grab a bite and fuel. Went to get on the ramp to get onto I-90 Westbound, It would not get into gear even when in the Sport mode tried that to see it made a difference. finally made it home after a few toll booths and a few shudders going through them as I got back to speed,.

Got home and hooked the SCT X4 to pull a code and got the dreaded
P0756 - Shift Solenoid 'B' Performance or Stuck Off

 

[SHOdded]

Still qualify for warranty coverage, I hope?

 

[Sholab1]

14.5K on it have a 150k 6y warranty

So I am good

Now to take unleashed off and 3bar, should I switch thermostat back also?

 

[SHOdded]

Nope, tune & 3 bar is sufficient.

Sholab, is your car a 2016?

 

[Sholab1]

Sorry, I'm new to the P0756. Is it just a shift solenoid that craps out? Or is it an indication of something more severe?

Transmission issues on multiple 2016 vehicles on both Ford and GM vehicles (shared design). We're starting to see a lot of these. Direct clutch hub breaks at snap ring.

Try the KAM reset procedure. If the code is in the PCM, clear it also and try driving again.

check your build date by VIN on

I reset the KAM with the SCT, Code is gone but still no reverse, pushed it out of driveway.
Rolls easy for such a heavy car.

Got to get it 63 road miles (1 hour)to dealer, if i make it 30 miles, Ford will come get me, 35 mile tow option on policy

Better have your guns at the ready, padre, if you're gonna slake your thirst at the saloon! Wow, long way to the dealer ... Have those hazards on ...

Yup to the above. If it's the issue in the TSB, if you can, get them to replace the transaxle. The direct clutch cylinder/tone wheel is a large aluminum pan shaped part and the area where the snap ring resides looks to have been machined way to thin. Part of me says drive it to the point of destruction so they have to replace it, the other side would be concerned that if they don't replace it and you drive it excessively that it puts a shit load of metal fragments (mostly aluminum) through the transaxle and coolers. Even with the proper flushing equipment it's a fairytale to think you're getting everything out and we've seen repeat failures in some cases. The dealer is going to run a series of pinpoint tests to determine the failure and repair it, it's quite possible that the issue in the TSB has nothing to do with what's happening with your car. At some point I'll probably tune my 13, but I have to say if I had a 15/16my that was tuned, in the back of my mind I'd have concerns about it being a ticking time bomb. If you had the failure, Fords going to try to make it out to be the tune that caused it and the Tuner is going to point to the TSB on a known issue, meanwhile you're stuck in the middle. CYA and make any sign of tuning go away before bringing it to the dealer. Good luck and best wishes.

Will differ to the more knowledgeable ones in here. anything can happen at anytime for any unknown reason

Sholab, I know it looks horrible but it's fairly painless with a lift. The big youngsters that works in the bay next to me is our go to for transmission work and typically has it out on the bench in a bit over 2hrs and he's not a hack. Not nearly as intrusive as it looks.
