Hello,

New owner of a 2019 F-150 V8 Lariat 10 speed transmission with 181K miles. Does anyone else have this issue and a potential solution?

The truck has a recurring shudder/vibration that you can feel throughout the car. Below are our notes:

no transmission codes
transmission shifts great and no hesitation or lag or jerk
shudder happens mainly under 2K RPM in all drive modes (normal to sport)
shudder happens through all gears, but hard to say in every one (as you accelerate and get to cruising speed 1-10 gear)
shudder happens right after take off and continues in short intervals while driving
shudder is harder (more often) and in few cases less vibrant
shudder happens when you are pressing the gas to increase or maintain speed
while at cruising speed in D and then N, shudder stops
there is a swishing noise (like metal to metal not very loud), it seems that as the driveshaft is rotating (not the break pads and rotors)
disconnected battery for 30 min (to relearn transmission), still the same

 

Many times an engine misfire problem can seem like a trans problem.
Are there any engine codes?

Do you know why the vehicle was for sale ? Did it have the problem from the first time you brought it home?

All these questions need answers before throwing out a laundry list of possibilities.
Maintenance history is very important.

 

The only engine code is P0430. It was present when we bought it and shudder was present. Truck has not had major repairs, regular oil changes. Thanks for your reply.

 

It seems there are problems with the some of Fords torque converters.
From what you describe, it sounds like a torque converter replacement is on the horizon.

Because it can cost over $1,000.00, that is probably why it was decided to unload the vehicle.
Suggest you obtain a few estimates for that job.
The trans has to come out, filter and fluid replaced along with the torque converter and you should be good to go.
For that kind of $$$, get other opinions and estimates..

 

Thank you for the response and direction. Will reply back with our findings.

 

FWIW:

I don't know if this matches your issue, but just in case...

I had a 2000 Taurus that would exhibit a hard misfire on a certain grade at a certain throttle position. This would happen almost daily at the same location as I traveled home from work. Rarely threw a code and never when the misfire occurred, but when it did, it pointed to the EGR system. It felt sometimes like it was dropping the transmission! After trying a few diagnostic procedures from the Ford Forum and YouTube videos, I found that it was the "EGR sensor" - maybe not the correct term, but it's what I remember. After replacing that sensor, I never had the grade/throttle position misfire again. My '05 F150 is having the exact same symptoms, and I can count on a couple locations going into town that it will misfire regularly as well. After years of experiencing and researching this problem, my car gave up the ghost a few months later to a Swiss Cheese engine cradle. With the rockers going bad and some other issues, it was time to put her to rest.
