The transmission in my new CR-V failed after 7 days and 50KM running. on 2013 Honda CR-V

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

READ your WARRANTY book carefully, maybe an attorney.
