My Frontier starts to develop a weird harmonic buzzing type of vibration when it's in between 5th and 6th gear we coasting around 40 mph. It goes away when you get below 20 mpg, and goes away after 50 mph. But again, it engages typically around 40 mph and you can feel it more pronounced when you're just coasting. The buzz feel transmits through out the cabin and definitely more noticeable on the steering wheel and dead pedal. I try putting the truck in neutral when I'm coasting but doesn't do anything. The buzzing engages about 75% of the time.
Update from Jun 21, 2024: After working with the dealer, there was nothing wrong with the transmission. An accessory rack was causing the truck to vibrate intermittently and that now has been addressed. The truck is fine.
