Automatic Transmission Control Module problems of the 2014 Dodge Avenger

I was less than 1 mile from home. I noticed the throttle wasnt responding as it should when I pressed the pedal. The etc light was blinking and the traction light was on. I was not able to drive over 20 mph and I was almost rear ended by the vehicle behind me. After having it towed and having two mechanics look at it, they determined it to be a throttle body failure. This was replaced. I picked the car up. Less than 1/2 a mile from the shop, I lost power again and the same lights reappeared with the engine light now lit up. I took it back. He ran the code and it was showing possible an vacuum issue. He kept it over night to take a looked at it again. It was determined their was no vacuum issue and now a code for the map sensor was being reported. It was replaced and the mechanic drove it three times at different distances. No issues. I pick the car up. I get almost home (3 miles away). Etc light blinks, engine light on, traction light on. At this point the mechinca believes it to be the pcm which he says is a common issue with Dodges. So at this point he is going to put the old throttle body and map sensor back on and replaced the pcm.
