Car either stalls out, turns off, or rapidly decelerates at random times. Transmission not shifting or staying in gear properly causing near collisions on several accounts, stalling in the middle of intersections, etc. . . Mechanic said coolant in transmission and transmission fluid in coolant system. Seems to be triggering multiple mechanical failures codes from transmission, to misfires, to O2 sensors. Afraid to drive. It's been sitting parked for multiple months very dangerous!.
