The dealer will only replace the transmission, but I am not happy, and want the car replaced.
The replacement is a difficult operation, and I fear being left with a Lemon.
Can you advise me, what I should do to insist that a vehicle this new should be replaced

The dealer checked the car out & agreed that there is a rumble, they re-balanced the tires, but no real change. They suggested that I put in a better gas, which I've done, but still no change. Does anyone have any suggestions?
