The code P1744 is California only transmission slippage detected. The torque converter clutch (TCC) would be one way it would do this. This would also occur if the transmission fluid was low. Check that. Anavel is right in saying the TCC solenoid would only have to be changed or the torque converter clutch itself. This is a far cry from getting the transmission replaced. You're looking at a $500 repair. Not a $2000 repair.
The code P1000 is OBD11 Drive cycle is not complete. This means the check of all systems was not completed since last memory clear. Perform OBD11 Drive Cycle. The last time the brain box for the engine was checked the things needed to do it weren't followed all the way through. This is a low dollar fix. Maybe $50 or so.
The code P1443 is Evaporative emissions control valve is not working. This is
a valve that opens and closes to control gasoline vapors from the tank. This allows excess vapors to be reburned rather than polluting the environment. This is probably a very low dollar function to be done. Probably in the $75 to
$100 range.
