Fix for a 2015 F150 with weird cruising vibration

I was getting the infamous intermittent driveline vibration when cruisin my truck at steady speed on a highway or a hill. It would feel as is the driveshaft was imbalanced or that it had badly aligned tires. Here’s my cheap alternative rather than taking it to a dealer for diagnosis or have them beat me around and take my money. This method actually worked! Truck drives like normal again..

1. Place the truck on ramps or jackstands
2. Lower the plastic undertray to gain access to the fill port bolt
3. Remove bolt
4. Pour fluid in
5. Put it all back together and pray you e saved yourself a trip to the transmission shop 😃

Thanks a lot for making this video! My 2016 driveline felt like U joints going out or really imbalanced wheels when going up hill on cruise. It was getting bad. I went and bought this magic juice and BAM it’s back to normal 🤯🥹 I was getting worried. Thanks again.

Big thanks for the video my 2015 F150 was doing the same shutter, shaking noise too. Watched your video and and add the magic portion and it worked great, thanks so much

this is a real miracle for torque converter shudder, i used it years back, and it worked instantinusly

Dude I'm having this same issue for months now and going to have to try it out at least...I've seen several around the web that say it worked ....thanks for sharing this

It worked on mine for about 15k miles. Going to buy more to add it a second time. Thinking of just changing my trans fluid. I’m at 109k now on my 2016 5.0

Helped mine too! I forgot to do a video on it. Thanks 👍

So i watched your video, my 2016 had a shudder low rpm acceleration at highway speeds, and i bought the tube of shudder stop. I changed my mind though after some procrastination and i decided to get a full transmission flush first to see if that would help. Well it was 470 bucks but it is smooth as butter now with no shudder at all. Mechanic said the fluid was burnt but not alarming and everything else looked good very few metal shavings on the magnet. I'm at 191k miles and he agreed it probably hasn't been flushed before so i hope this helps someone that has the issue.

My 2015 Ford F150 with 82, 000 miles was having the same issue... I put the tube of Instant Shutter Fix in the transmission and it worked. Hopefully the shutter will not return

Mines doing the exact same thing saw two videos about this shudder fix going to get it tomorrow and test it out heard nothing but great reviews, were you able to find a permanent fix yet?

[MrMaxyield]

Just checking in. Is the shudder still gone...??
Good video btw, thinking i might need to try this.. .
14' F150 lariat 2x4 67K miles. Shudder at 80mph +

I have a 2018 f-150 lariat that I just bought and it feels like a wobble coming from the back right tire I feel it in the steering wheel and even see the mirror and seat shaking it even causes the truck to do little micro swerves randomly, I took it back to the dealership and they said my alignment driveshaft suspension and bushings are good :/

Does it sound like you hit a rumble strip on the side of the highway that’s what I’m hearing

[Branhawk]

I’m gonna try this my truck vibrates at highway speeds and my tires and alignment are good.

[lordspam]

i like your floorboard friend. what a cutie! also thanks for the post. I changed my fluid at 90k because 100k is too long on these transmissions, especially if you tow a good bit. will give this a try for that vibration on the highway that comes out of nowhere. been there for years.

[coreyblalock]

Mine has a shudder when letting off the gas arounds 70 mph. You think this might help that issue?

[claytonclosson]

Do you simply add it to the transmission via the fill pint under the vehicle?

[jeremyrawlings]

Did it feel like a flat spot on the rear tire? I've had my tires balanced 4 times this month to rule it out

[a_cornell]

It worked on my 2016 5.0 6peed. Shudder gone completely

[hanynowsky]

Was your vibration RPM specific or road speed specific? Acceleration related or during decerelation?

[marksmith]

Did it sound like you kept going over rumble strips?
