I have a 2017 Reserve with the 3.7 engine and am having some concerns and questions about the performance of the transmission. Specifically at low speeds. When in traffic or when starting out and then having to slow immediately by taking my foot off the gas the transmission obviously downshifts. However, in this scenario it does so with what I would describe as a thud and/or a jolt. I have never had this occur before in all of the vehicles I have owned. It also does this on occasion when applying the brakes while going downhill and here in southwestern PA we are always going uphill or downhill. So that is my concern. Now here are the questions. First is anyone else experiencing this issue? Second, does anyone know if there are adjustments that can be made to the transmission what would potentially solve the problem? I have not discussed this as yet with the service folks, but I have the feeling that they are going to tell me that either they could not duplicate the issue or that it is operating normally. Please feel free to weigh in. Thanks.

(2) Tranny adjustments can be made both mechanically & via software programming.
A test ride with a dealer service rep should be able to verify what you're experiencing and/or an assessment of your TCM (Transmission Control Module) may correct the issue if required.
Edit to #1: On one or two occasions with a cold engine just after gently accelerating forward (after backing out of my garage) and changing my mind to check my curbside mailbox, the tranny did a nearly inconspicuous thud precisely at the 1-2 shift point. I believe the tranny programming is caught at an awkward moment of sorting out conflicting upshift-downshift commands by my change of intent. I've never considered those occurrences to be an issue.

Spoke with the service manager at my dealership, Benson Lincoln, here is Pittsburgh regarding the problem I am experiencing. He tells me that this is NOMAL as the transmission is between shifts and that it is a common complaint. He also tells me that there is nothing for Lincoln/Ford regarding reprograming at this point. He told me to drive it some more and that if it gets worse to bring it in and they will road test it. I don't know what that will prove if there is nothing to be done. I have been driving a LONG time with many different vehicles and I have never experienced this issue. I really like my vehicle, but in my experience this just does not seem normal. This really takes the bloom off the rose.

As a follow up to my earlier post, does anyone know exactly what can they check regarding the transmission operation and what adjustments, if any, can be made. It would seem that if the transmission does not "throw and code" they will do nothing. What exactly can they check without a code? What can they adjust and/or reprogram? Can they set the transmission codes back to what they were when it left the factory. I want something done but I don't want to act like I have no idea what I am talking about when I press this problem with the dealer. My initial plan is to have them give me a loaner for a day or a weekend to see if what I am experiencing is "normal" and if not I want to move forward with service. Thanks for the help.

Just a quick update for those of you who may be interested. I had the car back to the dealership and although they found no codes, they reset the keep alive memory (what ever that is) and reset the transmission tables. Two days in it seems to be better. I will just have to keep an eye on it to see if it stays that way. Keeping in mind that a little knowledge is dangerous and according to a YouTube video, it would seem that the same thing can be accomplished by disconnecting the battery for fifteen minutes or so and them warming the car up to normal temp and driving it normally (not aggressively) for about ten to fifteen minutes so that the PCM can relearn the shift points etc.

The first is an non-volatile (permanent) memory (in the form of an EPROM) that stores the VIN, default settings for the engine and drivetrain, milage, etc.
The second is a volatile memory that's is powered only when tbe car is running. It stores only those items needed during its current trip. It goes dead and is cleared when the car is shut off.
The third type is the keep alive memory. This is powered directly from the battery.
It holds the learned transmission shift points, sensor calibrations and the like. I believe that there is also a large, perhaps 1mF capacitor, used as a backup to maintain the memory when the battery is disconnected. The capacitor is the reason you would need to keep the battery disconnected for several minutes (don't know the exact amount of time, I would imagine 15 minutes would be sufficient).
As they chose to maintain the KAM they probably did so to keep your learned settings while changing the transmission settings to the new values. This allowed you to be able to drive the car smoothly right after service.

Well, I am back to having the same shift problems. I considered disconnecting the battery, but it will go in shortly for its first oil change and I am going to ask them to do what they did in July. Does anyone know what the process entails to reset the Keep alive memory and also reset the transmission codes? Is this a few minutes of programming or do you think that they will just do the battery thing?

I have a 2016 Lincoln MKX with a down shift problem from 2nd to 1st. It clunks or bangs. After taking it to a dealer in Edmonton (Waterloo motors) they put on 30 Kilos trying to find the problem and said they couldn't replicate problem. As a result they charged me over $250.00 and did nothing.(car is still under warranty) I also have a jerky brake problem and I am afraid to take it in again and be charged for nothing. This would have been noticeable in their 30 kilometer "test run". We will see if they can fix wind noise on passenger of vehicle first. Very very disappointed in Fords luxury brand.

What? Never heard of such thing. These guys needs a kick in the nuts.
Short of calling your Credit Card company to have the charge reverse, get in touch with the regional manager.
There is no way you should be paying for a "No Fault Found" while the car is under warranty.

My vehicle goes in for service tomorrow morning. As I'm getting a harsh two/three shift under light throttle I'm going to talk to them about this again. I really don't think that they have anyone qualified to handle the problem.
Here's a video from FordTechMakuloco that explains it in more detail:
