Was driving to work 1 morning as soon as I got off the fwy and came to a stop at the light, my car stopped engaging and turned off in D. It rolled forward and but I put brakes and then put it into park and had it towed out to a shop nearby, they said it was the transmission and it needed a rebuild but I couldn’t afford it and had the transmission swapped instead, now the engine is misfiring and It’s reading a lot of bad sensors ? I’m wondering what could’ve happened if the car is as good as done ?

 

well first i would take it back to who did the work most of the codes are things left unplugged.
