Car Stall problems of the 2015 Dodge Challenger

I own a 2015 Dodge Challenger. While driving various speeds the vehicle will randomly stall and display "come to a complete stop and select the appropriate gear. " this has happened 10-15 times. I have taken the vehicle to a Dodge dealership 3 times. On the second visit they replaced the transmission and valve body. I left the dealership and was only 4 blocks away and the vehicle stalled and displayed the same error. The vehicle is currently at the dealership and they say they cannot duplicate what is happening, so they don't know how to troubleshoot the problem. This started happening at approximately 16,000 miles.
