The car shakes at 3krpm but doesn't at 2 and 4k rpm when shifting.
The car shifts fine doesn't slip or struggle to get into drive or reverse. Doesnt shake at idle either....

It vibrates hard at 3krpm when I'm on the highway
And it's really loud.

Mileage is 92k 09 barbus 451 US.

Help?

start by checking tires and rims for bent or out of balance, or low/high tire pressure. grab each wheel and try to shake it, loose lug bolts or shocks

My experience with bad motor mounts is a 'shake' while idling, not while the car is moving.

I had a car with bad motor mounts, it shook so bad at idle it was like getting a massage.

Vibration at 3k rpm in what gear? Every gear? Or is it a certain speed causing the issue? Is this while shifting as the title of this thread suggests, or while maintaining steady 3k rpms? Clarifying the concern is as important as the answer you are seeking...
