I recently did a transmission service on my 2019 f150 lariat.
a day after the service, i pulled a holiday trailer(6000lbs).
on the way back from camping the truck was starting to act weird.
to me it was the same feeling as a failing coil pack. my truck has
140,000km(87,000miles). i got a new engine under warranty @ 120,000km(75,000 miles)
i took it into the dealer because ford gave me full engine warranty to 200,000km which covers spark plugs and coil pack as well. when they scanned the truck, they got these codes:
p2769 - Torque Converter Clutch Circuit Low
p0743 - Torque Converter Clutch Solenoid Circuit Electrical
p2760 - Torque converter clutch pressure Control Solenoid Control Circuit Intermittent

Anyone ever have this issue?
Is it as easy as a new valve body?(new valve body assembly comes with all new solenoids)

 

No one has anything to suggest?

 

What type of service did you get? Did they do a flush or drop the pan?

 

dropped the pan, fluid/filter/inspection.

 

also, as an update, I have been driving the truck u til my transmission guy can get me in. It makes a firm shift when going into drive, going into third, down shifting from 10 to 9 and down shifting into 3rd. Two days ago, the truck threw every fault code(hill decent fault, parking sensor fault, traction fault, park brake fault, engine over temp, trans over temp, etc) and the engine shut down. Press the start button and it wouldn’t even turn over. Pushed my truck into a parking spot and it sat for 20 minutes. Tried to start it as my wife picked me up and the truck started and no faults came up.

 

My thoughts would be to look for the obvious first, electrical connections and fluid level. After that I'm really not sure as I do believe there are electronics in the pan controlling the solenoids.

 

***UPDATE***
turns out the transmission harness either came off or was never hung properly and the harness fell on the exhaust and melted. My engine was replaced a year ago so they for sure had the harness unpinned. Replaced the harness and all issues went away

 

Whenever the specter of "engine replaced" comes up in discussion there are a myriad of problems that can occur. I am glad yours was an "easy" fix!!

 

Both codes tell that the Torque Pressure control Solenoid >>>>circuit <<< is electrically open or intermittent.
The PCM is not detecting a voltage drop across that Solenoid when the Ignition is turned on (powered up).
Do not involve a whole valve Body for this fault, ....for one electrical circuit fault.
When intermittent while driving it would feel like an intermittent misfire when the Lock-up comes off and one reflecting a change in engine RPM under pulling torque. The Converter is supposed to stay locked all the time, except when not moving.
Good luck.

 

it ended up being the main transmission harness
