Automatic Transmission Control Module problems of the 2008 Chrysler 300

I bought this vehicle, thinking it was great. I tried driving it home, and never made it. I lost all power on the highway in front of the semi. In return I did not have brakes, I didn't have steering, all lights turned off, and to top it off it wouldn't start again. I've replaced the pcm, starter, alternator, the power distribution, all the fuses/relays, and here I am still spending hundreds of dollars to try to get my vehicle to work again, and it's not seeming possible. I have 2 kids and now once I get it started I must worry if it'll happen again. The car only has 120,000 miles on it. It's been very well kept. And now I've bought all these parts and paid all this money to have it repaired. And now I'm out of my other vehicle, and with the corona virus I am out of work, and have no way to keep spending money to fix it or find out the problem. The electric light was on I replaced throttle and sensor as well. That didn't fix it neither.
