Bought my 2018 Raptor originally. Have had chronic problems with hard shifting and 'clunks' shifting out of 3-4th gear, when coasting and at highway speeds when quickly accelerating to pass. I have had the truck into Ford service six times with this problem. They've replaced the valve body twice. Just got it back from service two weeks ago and it's started doing it again. Has anyone seen this type of problem?

I’m sure I’ve read some posts about this issue in another section of the forum. Maybe try checking in the drivetrain section.

I have a 2018 with the exact same issue. I just noticed it after I had the cam phasers work and updates done a couple months ago.

If you had recall 21B10 done than you already have the latest software. You may want to try doing an adaptive relearn.

NOTE: Perform the adaptive learning drive cycle on a level road surface.

  1. Using the scan tool, clear the DTCs (Diagnostic Trouble Codes) and Transmission Adaptive Tables.
  2. Drive the vehicle until the engine and transmission reach normal operating temperature.
  3. Accelerate from a stop with light throttle (15%) ensuring that upshifts 1st through 8th occur at engine speeds between 1300-1600 rpm.
  4. Continue to accelerate (may apply slightly more throttle after 7-8 upshift at 32-38 mph (51-61 km/h) until you achieve 55 mph (88 km/h) and the 8-9 and 9-10 shifts complete.
  5. Brake very gently to a complete stop and hold foot on brake for five (5) seconds.
  6. Shift the transmission to Neutral. Wait 1 second.
  7. Shift the transmission to Reverse. Wait 2 seconds.
  8. Shift the transmission to Neutral. Wait 1 second.
  9. Shift the transmission to Drive. Wait 2 seconds.
  10. Repeat Steps 3 through 9 six additional times.

If adaptive relearning procedure doesn't work.... Cobb has the fix. Access port with TCM.

YouTube has a few posts with successful happy customers that had your exact symptoms. Do a search. You will see the light.

It is software related. Fixes the dreaded shudder as well.
I hope Ford gives Cobb a call. Gen 3s are starting to have these issues as well... I have read on other forums. Even GM products with this same transmission.

I can't imagine how much this is costing Ford in repeatedly opening transmissions and replacing perfectly good valve bodies. I have even read that owners are having their entire transmission exchanged for a new one.

Is there something we are missing or do not understand? I am not a professional mechanic. So wtf do I know. So frustrating.
