TSB 20-2277 2019-2020 Ranger - Shudder/Vibration When Accelerating From A Stop

[Willis]

My truck started shuddering at about 33k and it went to the shop today. They said it would take minimum two days to fix. Is this the normal time range?

Update it only took about an hour and didn’t help it at all. Not very happy.

It's odd that your shuddering didn't start until 33k miles. Did you recently do any suspension work to the truck? Most trucks that have the shudder come with it. Is the shudder only at take-off, around 10 to 15 mph?

Nope totally stock. It’s at about 30 to 45 mph is the worse. But highway driving is normal. If I am in town it is terrible. Been totally happy with my truck as I have had many Rangers in past and my dad has also. He still has his 97 splash in the garage lol. But to have the mechanic verify it is fixed when it isn’t really has made me down. I don’t want to keep running to the car lot as I like everybody else just doesn’t have the time.

I would suspect this isn't the same take-off shudder that TSB 20-2277 covers. As much as you don't want to have to go back to the dealership you will probably have to. Make sure a tech does a ride along with you so you can show when and where the problem happens. Do you have a description of the work they did recently?

Yea they drove the truck and I rode with them before they did the tsb.

30-45mph? That's definitely not start up shudder. More likely you have an issue with a wheel that threw a weight and is no longer in balance correctly.

Super odd that they would have applied that tsb (which specifically addresses shudders when first starting from a stop, not when cruising) after riding with you and feeling the behavior.

It's incredibly frustrating to me that the people who are supposed to be qualified to address concerns with these trucks seem not to be at all. :-(

I am a slow convert to the start up shudder not being my issue. I have had techs and shop foremen ride with me and tell me that even though what they feel in my truck is the worst they have ever experienced with the bucking and shaking while steady in a gear (not shifting), the truck was operating as designed and neither their shop nor Ford was going to pay them to work on it. I gave up on them even attempting to find the problem. As suggested elsewhere in this thread, when I start the engine, I put it in tow mode (and strangle the auto start feature), That holds the trans to shifting later, and the engine rpms are kept to about 2000 RPM, and the issue has virtually gone away. I am assuming you have a tow package, obviously. Hit the button on the side of your shifter and you can see that the trans is not shifting to 8th gear by the time you hit 30 mph. If I am going to drive over 40 mph and at highway speeds, I take the tow mode off. And they did the TSB (wrong, but they did it) to shut me up.

I plan on getting my wheels and tires balanced tomorrow. I hope this helps.

I'd love to know if it makes any difference.

Welp it didn’t help.

Has anyone tried for shits and giggles removing the rear leaf blocks (but keeping one on the drivers side to compensate for the lower left side) that came stock with the truck, which would lower the rear and see if that fixes vibration issues? I had vibration issues since stock but not terrible. After my 3" eibach leveling struts, its bad.

It's interesting you mention that. I recently saw some rear suspension pictures of a 2019 Ranger Lariat Crew Cab that is confirmed to have no take off shudder. It only has one leaf block on the left and none on the right.

You know what I noticed today? The front left side sits lower than the front right side by 3/8”. Do you think that could cause vibration? I have the rough country 2.5” leveling struts on my truck

I just saw this post and I’m pretty sure my new tremor is behaving the exact same as you describe. In normal D mode when cruising at 30mph and giving light throttle the rpms drop too low and the truck shutters/vibrates and just feels horrible. Seems to happen below 1500rpm in certain situations.

tow mode and sport mode above 2k rpm and everything is butter smooth and fine. Is this what your describing? Almost feels like the engine is lugging. I’v been debating about taking it in to Ford but maybe it’s normal. Idk. Tow mode and sport mode are awesome and no issues but regular D sucks lol
Any updates on yours?
