Transmission shifting down violently

Recently had 4 instances of shifting from 10th to around 5th running at 80. Very concerning as it felt like i was leaving the transmission on the highway. Took the truck into the Ford dealer and the tech could not replicate the problem. They agreed to install a computer that was hooked to a handle with a button that I depress and it records for a period of 30 seconds. Took the truck home (1 hour drive) and it occurred twice at around 85 mph. I hit the record button as it occurred. Now truck is back into the dealer and hoping to hear what they pull from the recorder.

Anyone with a similar problem?

 

I’ve seen similar to this reported on here before by other users.

 

Ford has a Technical Service Bulletin out on this that pertained to my GEN1. The abrupt downshift problem never happened to me, but the dealer checked my rig out, gave me a thumbs up, and extended the warranty on my transmission.

 

My '18 2.7eb would, on rare occasion, kick down so hard the t/c light briefly illuminated and it felt like the tranny might actually fall out! The first one or two cold 3-4 shifts were also rather "firm". I never could find and answer or explanation. Waiting to see if my '18 Raptor behaves similarly...

 

Have my '17 in the shop now for cam phasers and a similar issue with the transmission. If I accelerate and let off of the gas and reaccelerate, it will abruptly shift and is very noticeable. Sometimes if feels like the transmission is about to drop out onto the road. They've previously flashed the TCM and also replaced some type of transmission control assembly (may be incorrect on the actual part - service records are with the truck right now), but the issue has persisted. Hoping that they can identify and repair both problems and I'll be back in action soon. I'll let you know what I learn.

 

I’ve heard of this happening on rare occasions.....hope they fix the issue.

 

I have had it happen a couple of times as well. Only in normal mode with all the gear skipping. I haven't had it occur in sport mode. Just out of curiosity what modes are you in when it happens?

 

I was in regular mode running at 82 with cruise on when it shifted down abruptly.

 

Have you had Ford look at it? If so, what did they say/do?

thanks

 

Dealer tried a new TCM update on mine and there is still an issue between shift 7 - 9. They now plan to replace a shift solenoid, which has not been replaced yet. Fingers crossed.
