Transmission grinds on acceleration. Also, rumbling sound/feeling between approx. 4th and 7th gear. When shifting from park into reverse, vehicle lurches and loud bang. Have had the vehicle in the dealership 3 times, and all 3 times, they say they were unable to duplicate the sound. I guess if they can't hear it, it's not a problem. Definitely 100% without a doubt, this vehicle has a transmission problem.
