Codes P0008/ P0016, P0017 and P0018, car starts but will not drive?

Was driving my car, came to a stop, put it in park and then in drive again and car would not move. Stomped on the gas switched into park, reverse and park again and eventually turned car off and back on then car slowly crept into gear. But barely picked up speed, got to about 35 and when slowed to a stop it would hesitate to move again when pressing the gas. Finally made it home and hooked up reader and codes P0008/ P0016/P0017/P0018. So, I changed out the crankshaft position sensor and the car then wouldn’t even start, all codes went away except for now it read a connection code, so I replaced the crankshaft position sensor connector, and it still won’t start. Took new sensor out and replaced with old sensor and car started to crank over but is now throwing a different code. I thought for sure it was the shift solenoids A and B but no code comes up for that. But that is almost exactly how the car is behaving. I am at a total loss.
