Just bought 2019 Lariat with 33,000 miles, 3.5 eco boost engine and I think there’s a transmission problem. At low speeds 30 to 35mph in 5,6,7 or 8th gear the truck vibrates, up to shuttering especially when slowing down. It’s still in the 90 day dealer warranty and I don’t want to go past that before having it looked at. I just had the wheels aliagned and four new Michelin tires installed, so I Don’t think that’s the problem. Any insight from others with this issue?

 

Did it do it before tires and alignment? Sounds suspect.

 

I had a defective tire, brand new set installed by the dealer I bought the truck from. They were some tire brand I had never heard from out of Indonesia! At 70 mpg I was getting a tire vibration and when I had the tires inspected and rebalanced using the Hunter road force balancer, one front tire would not balance, that’s why the alignment and now new Costco Michelins !

 

I read the older 3.5 had a bad problem with shuddering coming from torque converter
Not sure if its still a issue because it was the 6 speed back then

 

Not challenging the Michelins, but last truck I owned, I put Firestone Destination tires on it at a Firestone shop. Took road force balancing at seriously, 9 tires, to get 4 that passed balancing. Goofy things happen. I'm also not defending the 10r transmission, it is known for shuttering. Maybe start by rotating tires front to rear and see if anything changes in drive?

 

THANK YOU, I’m going to take it to Brandon Ford and have them check it and get a repair estimate, then I’m going to take it back to the Nissan dealer where I bought it from and has to honor the 90 day warranty. I will see if it’s something they can properly fix as it’s a Ford. If not then the fun starts!
