Transmission issue

[allcos]

I have about 44500 miles on the truck with the Premium ESP insurance plan.
About 2 weeks ago while I was coming to a stop the truck jolted like someone tapped my bumper. I looked back and the car behind me was a few feet back. Oh...here we go. It's been doing it occasionally. Well, yesterday I had it at the dealer to check it and they said they couldn't repeat it. I said "occasionally'. They said they checked the level, the fluid, codes and found nothing. It may be a $200 Diagnostic charge for something I know is there, but they didn't find it. Any ideas/suggestions?
To add to this my damper door servo(s) are clicking. They agreed and plan on doing the dirty deed of replacing the unit.

Could be the slip yoke binding on the driveshaft. Known issue

Have you ever changed the fluid? My transmission had those signs. Fluid change and LubeGard Platinum cured it.

My ranger has done this since day 1, my last 2 F150s did the same thing. I think it’s a Ford thing. I’ve read it has something to do with the 2 piece driveshaft. Idk.

Both my 5g Rangers did that every so blue moon. Like i was rear ended. 40k on my 2020 60k on my 2022. Other than that, transmission worked fine on both. At 40k on my 6g Ranger and the transmission/driveline has never done it. never could figure what it was.

Have the dealer follow the procedure for testing the transmission in the linked TSB

10R80 TSB

That test will tell if the CDF has shifted and needs to be replaced.

I took my truck in numerous times for shifting issues only to be told No Problem Found.

I had them do that test and they found the CDF leaking pressure.

I got a fully rebuilt transmission with all the updated parts and a new valve body, all covered by my extended service plan.

What year is your truck ? If its a 10980 tranny you are heading for a complete failure eventually . Ford & GM designed this 10 spd together & are both having issues with this transmission starting around 2019 . Mine went with only12,589 km . A bushing in the cbd shifts causing shifting problems , Ford & Chev know about the problem & never issued a recall . ITs a $ 7,500 rebuild if your warranty is up . Ford & Chev have in several of their vehicles with this transmission & I believe they both didn`t put out a recall because it would be a huge cost to them.
