Hey Aggie, how many miles do you have now? Do you think this transmission issue is related to the PCM re-flash that comes with the phaser repair??What dealer did you go to in DFW? Really hoping it's not Park Cities.

They did, literally, the exact same thing on mine. They said everything checked out, nothing wrong anywhere. Suggested that perhaps it got a glitch in the “adaptive process” along the way and that clearing the trans computer would allow it to learn from scratch without the glitch.After a week at the dealer, they finally got to my vehicle... and did basically nothing.
"Electronic transmission diag. KOEO pass. KOEC pass. KOER pass. Check fluid level and condition, OK. Reset KAM and shift tables. Perform adaptive drivecycle. PID monitor road test 15 miles at highway speeds verify repair."
So they basically just checked the logs and reset the software.
Something tells me I'm going to be back at the dealer before long. GRRRRRR.
Has this been resolved yet as I’m experiencing a similar issue. They reset the PCM 3 times including a software update. Still happens but not all the time.Have a '19 Expedition Limited 4WD. This issue has been occuring in 2H mode which i'm in 99.9% of the time.
At highway speeds (70-85mph) while coasting then attempting to accelerate (ie while trying to pass slower traffic), the car will lurch/make a clunk sound and "pop out of gear" (rpm’s will rise as if in neutral and car won’t accelerate). When you let off the gas, the transmission will lurch/make another loud clunk and engage a gear, then proceed to accelerate normally when you re-apply throttle. No errors/warnings on the dash. The clunk sounds are pretty painful to hear, not going to lie.
This happened once or twice yesterday on a 3 hour roadtrip, then at least 3-4 times today on the return trip earlier today.
Anyone experienced this/have any idea what the issue is? I've got 44K miles on the odometer, so I assume this would be covered under the powertrain warranty, but i'm quite annoyed that i'm having transmission problems on a car <2 years old and one with 95% highway miles and diligent maintenance.
Can I also ask if you are running stock wheel size? I have 35s on it nowHas this been resolved yet as I’m experiencing a similar issue. They reset the PCM 3 times including a software update. Still happens but not all the time.
