Tranny/engine

Okay so I put a new ignition in my Eddie Bauer Ford Expedition 2001 I had it flashed at the at the Ford dealership because I had to put a new ignition in it cuz the other one was drilled out no check engine lights or nothing was on when I got the car back so I drove it until I ran into it cycle and went and had it smog after I had a smogged I was trying to refill the air conditioning service port with an aftermarket tank bad bought put some more freon in it get a little colder okay in order to get the connection on I had to take off the solenoid and that bracket that holds all that wiring harness connections there that would be on the passenger side of the firewall of the expedition okay when I did this I don't know what I pulled wrong or what I yanked on too hard because it set off a chain reaction of of of codes immediately I mean I got it says that all of the O2 sensors are bad now it's telling me that the torque converter clutch has a bad wire on it it's saying that number number B solenoid in the transmission is bad A and B I think it is and all this s*** happened after I tried to charge the air conditioning which didn't get charged I started tracing around I found a couple bad hoses that were leaking vacuum hoses and I replaced them but still it hasn't fixed my problem if when he shifted into drive it's really soft when you hit Drive and it slipped bad the only way you can do it is to get it into low and get it going a little bit and then it kind of goes but I can't drive it like this and I just got it smogged I don't know what to do I don't know where to start with this stuff I'm going to go through and check every fuse and make sure that they're all good that I didn't burn out a bunch of fuses or something but what are you guys think what do you think I should start with this
