Vibration noise under acceleration 1200-1400 RPM

[Dodeboost]

Indeed, you should notice on decelerations a downshift right at the 36 and 25/26 mph ……..then hold it right there exactly.
The ironic thing it keeps one from getting a speeding ticket LOL.

30mph will always result in a luging situation as previously stated so if on extended 30mph drive switch mode to tow/haul sport. I find tow/haul much better than sport cause imo sport is ridiculously on the other side of the spectrum.

One could almost treat tow/haul as the normal mode and normal as a highway/overdrive mode.

tow/haul …….city
normal …….country and highway.

Like many here I sure hope Ford addresses this cause until they do I only give the 2.0 Mav an 8/10 otherwise would be 10/10 imo.

Good info here, I’m going to give that a shot. Pretty ridiculous we have to do this though. There shouldn’t be tricks to driving a brand new vehicle. Then again, it’s the first year of a new vehicle, so something like this isn’t totally surprising. Hopefully ford fixes it with an update. I absolutely love my maverick but this has really been bugging me.

Agreed on all counts. It’s BS that we have to deal with this and the trucks been out for over a year.

They better address this as well due to future warrantee claims of drivetrain / engine damage to owners that aren’t sensitive to this issue.

Good morning, Andrew! I'd like to look into your concerns. Feel free to send over a private message with your VIN and dealership info at your earliest convenience.

Same thing here. 23 eco boost awd. Annoying and embarrassing when giving others rides

Same thing here. Exactly same symptoms. Was just wondering if octane levels change any of the lugging we are feeling? I know it’s a trans shifting point issue but could the horsepower change from higher octane minimize the lugging? I’ve been running 87 , only 510 miles so far.

Ttried that. Makes no difference.
Indeed. New TCM flash from Ford is what we are awaiting.

Higher octane makes no difference for me either.

Mine does the exact same thing and is most obvious around 35 mph. It actually happens at any speed where the engine is below 1500 rpm and the throttle is applied (lightly enough that it doesn't downshift or unlock the torque converter). The vibration and noise, caused by the lugging, is just much more noticeable at low speeds because there is less road & wind noise/vibration.

I'm a mechanic with over 30 years of experience and it's obvious to me the problem is in the PCM/TCM programming. The programming is keeping the transmission in too high of a gear and keeping the torque converter locked, which is causing the vehicle to lug (like a manual trans in 4th gear when it should be in 2nd). This lug is causing engine/transmission/driveline vibration until it reaches that 1400-1500 RPM point. I'd guess this programming was done in an attempt to keep RPMs as low as possible for gas mileage, but it definitely causes unwanted (and possibly damaging) NVH (noise, vibration, harshness). Plus, the only thing that prevents the lug is pressing the throttle hard enough (probably about 25%) to cause the transmission to downshift which will definitely use more fuel. Ford needs to change the programming (put out a TSB with a reflash) to, at a minimum, unlock the converter on throttle tip-in below 1500 RPM (and probably have the trans drop a gear as well). I hope more people pay attention to this issue and report it to their dealer. We also need to tell the dealer to report it to Ford corporate, so they realize there's an issue (which I have already done, but it will take far more than one person).

As previously posted in numerous threads about this exact same thing with mine, I first noticed this about 3 months after taking delivery. In October in WI. I have noticed the severity get less as we got out of brutal winter temperatures. Almost not noticeable once about about 40F. Today was 80 and not noticeable at all. I’m thinking air temp (density), has something to do with this.

Yesterday I switched on the air conditioner and immediately my Mav went from wanting to lug to highly sensitive first gear. Waiting to see what happens today…….

Following. Mine makes the same vibration sound, similarly to a 'loose heatshield' sound. Took it local dealer & stated could not find anything. (2.0, awd w/4k)

interesting. If the AC makes the difference a long term solution could be to somehow “trick” the ECM/TCM to accommodate an always on AC?

Hey there. I can look into your Maverick’s vibration noise concerns on my end if you’d like. Will you send us a private message with your VIN and dealership info?

I gotta ask.

What is a "highly sensitive first gear"? I'm not familiar with that terminology.

 

[TC in MN]

Bad wording, enjoyed the ask. At a stop, touching the gas pedal and the truck leaps forward, almost awkwardly, and then, just a touch of gas to speed up when going down the road.

I’m hoping for whatever reason “the lug” is gone and a quick, smooth shifting truck is here to stay….

Taking the truck out tomorrow to put it thru the drive modes to see if the change has happened and if not, try to remember the sixty’s…..

OK, spent the morning trying to get the vibration noise “the lug” and happily not able to do so. In all drive modes, the transmission shifted up and down smoothly and appropriately.

It’s gotta be some type of computer glitch, but whatever it is, I’m hoping it’s gone for good!
