Vibration when taking off

[sebounet]

When i take off hard in manual mode for example, i can fill in the seat a vibration, it s look like abs.
There is no light on the dash board that appears. I have a gt automatic. Could it be the way the differential work ? As it s not a torsen but a clutch pack. Or the drive shaft ?
It s not noisy, or not enough to hear it.
I asked to the dealer but they said nothing wrong, i m not convinced

Could be a torque converter issue, but you'll likely have to take your service writer for a ride to verify he's felt it. I've had to do this almost every time I've needed something fixed.

Wheel hop? Do you have the standard GT wheels?

Yes standard 18 inches but with summer tires firestone indy500. What his wheel hop exactly.
The feeling is like you are driving on a gravel road and feel the gravel under the tires. But just on the rear.

But i really feel it in the middle or back of the car. It gives the impression of gears that skip some teeth sometimes. Like grab and ungrab

Like the car is driving over a washboard road?

This is wheel hop:


Really great example of IRS suspension wheel hop causes. It's long but educational.

Thank you, but i think you would hear the tire noise, and feel like the car is jumping a little. Also i can rpduce my problem for example in 5th gear, with full throttle at 50 mph so i don t think it could be wheel hop in this condition
