System Analysis Problems Help Please 02

Hi I'm looking for some answers. I have a 02 Cadi Deville with 98,935 miles on it I recently took it in for a system analysis check because the Check Engine Light is on. This is what I was told:

Code PO102 MAF Circuit Signal Low
Problem no present at this time

PO440 Evap, System Fault

PO443 Evap Purge Solenoid Control
Circuit Fault
Pigtail for Purge Solenoid

PO463 Fuel Level Sensor Circuit
Signal High/Open
Recommend Fuel Level Sending Unit

PO741 TCC Performance Stuck Off

P1862 Torque Converter Clutch
Solenoid Circuit Problem

What exactly does all of this mean and which should be address in order of importance. Lastly does anyone know the cost I'm lookin at?

Any suggestion are highly appreciated.. Lastly if anyone knows a good shop in the St. Louis Metro Area.

It sounds like there are a couple of problems with the torque converter in the transmission. That will probably require at least a new torque converter, or possibly a rebuilt transmission. The fuel level sender has a fault. Have you have erratic fuel readings? The other one was for the evaporative emissions system. It sounds like the purge solenoid is bad. I'd fix the trans first, the fuel gauge, then the evap system. I can't give an estimate on cost, but I'd try and find a reputable shop that can do the work. A dealer will be the most costly route.

Good luck.
