I couldn't find that this has been discussed.
Ford Expedition 2016.
About 150K miles.
For the last couple of weeks, my wife has reported that it studders when accelerating. I started driving it to better understand the issue.
This is what I have found.
It will do fine driving under about 45-50mph on flat roads.
When accelerating to interstate speeds, it will start to have random RPM fluctuations, lose power, and then if I don't let up on the acceleration, the mechanic wrench comes on. If it I let off on acceleration, then I can continue at a constant speed, but can't accelerate further.
If I go into Manual mode, I can accelerate without an issue.
I don't use manual mode often, but it seems that you can control when it shifts, but if it wants to shift down, then it will still do so without my input. It won't shift up without my input.
If I am highway speeds, if I shift down and keep RPMs higher, then there is no problem.
If I start to go up a hill in manual mode and don't shift down, it will try to shift down on its own, and then will have the same issue described above with fluctuating RPMs and no power. If I quickly let off the gas and shift down manually, I can stop the issue and continue driving.
I have a code reader. The first time I read the codes, I had a P0741. Torque Converter Clutch.
I spoke with someone who used to work in the Ford service department, and he said the solenoids are often a problem. Specifically the torque converter solenoid.
Interesting, I cleared the code to see if it threw it again when the problem happened and it hasn't triggered any codes.
As I looked into if I could replace the solenoid myself (which I determined I can't within my tools, skills, time) there were discussions that often multiple solenoids start to go out at the same time. People recommending replacing them all at once as most of the labor was getting to them in the first place.
I will take it in to a transmission shop, but am always hesitant of mechanics wanting to do a much bigger job when it might be something simple.
To me, it seems much more like a sensor issue and the solenoid would make sense if shifting manually before it otherwise wants to shift bypasses the issue.
Anyone have this issue? Any thoughts? Thank you.
