Hello, new member here just got my truck yesterday and been loving it for the most part. Had a strange issue today where in a low speed turn coasting off power into a parking lot the trans was sort of confused then popped/clunked into a lower gear. The first time it happened just thought it was one of those weird things that happen on occasion then it did it again the next time in a similar scenario. This is a 7.3 with 175 miles on it. Is it just weird break in stuff or is this how this trans is going to shift at low speeds? Anyone else had any low speed clunking/bucking issues when it downshifts?

Mike's been having odd transmission guessing as well, not terrible but noticeable. It's like the truck is still learning my driving habits. I'm not sure if there's anything wrong or just how it is for now.

Mine had some rough downshifts while coming to a stop during the test drive. I mentioned it to the salesman and he said the transmission would learn and adjust to my driving. I thought it was the typical response, but the issue didn't pop up after I had put a few hundred miles on.

Normal, transmission is learning, make sure you operate it in all kinds of conditions (make it downshift by more throttle imput) The more you drive it the better it will get. I am approaching 1,000 miles and is starting to smooth out finally.

I'm still having rough shifts but I've really been babying the thing. I'm around 1800 miles. I need to really get on it more in normal mode. Most my driving has been around town in eco.

Thanks for the reply's. Sounds like it could be a normal learning/break in thing, will give it a thousand miles of varied driving and see what happens. My wife had driven for the first half of this trip and I drove the second half...we have very different driving styles so maybe it got confused. :D

I took it out again just to try to duplicate the issue and watch the gears closely, there is definitely something funny happening with 2nd gear. It rarely seems to use 2nd and when it does it acts strange like it gets stuck momentarily or something. The only way I could get it to use 2nd was to slow to just above a crawl (other than using manual). Hope it will break in and start working better, we shall see. I dont fully understand the shift patterns yet but obviously with 10 speeds it could be pretty complicated. I think the buck/clunk I was feeling was the trans trying to go from 3rd to 1st, missing 2nd for whatever reason..

Mine rarely goes into second gear, you really have to give it a lot of throttle. Most of the time is goes from first to third. Hopefully yours will smooth out. I was really not a fan at first, but it is has been improving. In my wife's Aviator the 10 speed transmission has been awesome right off the dealership lot (best automatic I've driven, responsive and smooth), so I guess I had better expectations with my truck.

Well...truck isn't an ultra comfy plush Aviator...different tranny right? The heavy duty version.

Yes correct, but still. You would think it would be a little smoother.

Mine does the wierd stay in second thing an extra second, right after I pull out of the drive way. Other than that it skips gears all the time on upshifts. I have 7000 on mine now and its very smooth and quiet overall. Have not experienced a hard downshift, but sometimes when its idling at 20 mph with almost no RPM...it does kinda get almost in neutral like...and searches around a bit....other than that no problems

I have 2500 miles on mine. About 500 towing 4500 lbs, about 1750 miles highway and around 500 city.

Don’t baby it too hard. I wouldn’t blast it non stop, but floor it at highway speeds and pass some cars occasionally. Sometimes get on it hard when merging onto highways. I would always wait until transmission temps are up all the way until getting on it at all.

To me, I think you need to just drive it and let it learn how you want to drive. Give it some time. If it’s not a good transmission the. You’ll find out sooner rather than later.

I had a similar thing happen last week. I was starting from stopped and I thought someone rear-ended me. I looked in my rear-view mirror and didn't see anyone. All I can think of is that the transmission was confused. It happened somewhere between second and third gears. When I checked, it was in third. I wasn't doing anything abnormal or aggressive. I'll let you know if it happens again. I hope that its a 'learning' issue. It was not pleasant on a new truck with 1k miles.

Mine has about 4500 on it. Here in upstate NY, the summer morning temperatures have been consistent. I drive the the same route, same time of the day and I get different shifting experiences. Early august i documented the temperature for three straight days. It was 68 degrees everyday at 6:05 am. When backing out of driveway and engaging it into “drive” i noticed three different shift patterns. Ford dealership says thats “normal”. IMO, i dont care if its normal, for 70K, in 2020, i expect better! Rant over

There is a recall on the Tranny for trucks built in Jan and Feb.....there is a thread on this (Transmission Recall) go to the NHTSA web site and enter your VIN......and you will instantly know if your affected. The fix is a new Tranny
