I Have 7 codes on my 2000 Ford Taraus PO743, PO750, PO755, PO760, PO442, PO133, P1131. Would you be able to tell me what those problems are?

Sounds like transmission code, electrical issue. Did you get your problem resolved? I am having some of the same issues and am investigating my problem that's what I have come up with so far.

Chances are the transmission being in 3rd gear is a safety feature to help keep you from being stranded on the road.
All of the codes are transmission faults which means you will need to get it to a shop for diagnosis.
The codes are for shift solenoids and torque converter issues.

P0743 Torque Converter Clutch Circuit Electrical
P0760 Shift Solenoid C Malfunction

take it to your local ford dealer there is a possible recall

these all relate to the Transmission Control Module (TCM) i presume your experiencing gear change problems ,try replacing the transmission fluid as this can sometimes be the proble but as have three seperate codes to same component i'd investigate the transmission itself but give the fluid change a go first you might be lucky

they are a/t trans. codes 1 torque convertor clutch. 2 shift solenoid (SS) B. 3 SS C. 4 SS D.

code p0743 refers to torque converter clutch solenoid-electrical=== causes wiring--clutch solenoid ECM/TCM
code p0750 refers to shift solenoid--A circuit malfunction=== causes wiring --- shift solenoid --ECM/TCM
code p0755 refers to shift solenoid B --circuit malfunction=== causes -- wiring---shift solenoid ---ECM/TCM
First is to check the wiring and connections are in good condition. next is to replace the clutch solenoid for the torque converter and work up from there

go on google an type ford engine code and then the code

P0443 Evap purge control
P1747 Pressure control "A"
P0755 Shift solenoid "1" malfunction
P0750 Shift solenoid "A"
P0743 Torque convertor clutch circuit
P0113 Intake air temperature high input
For now leave the P0443 that is a evap code. for code 755 750 743 how did you get these code? clear it do key on engine running. the reason I say this is somewhere especially at the tranmission harness you are somehow disconnected. Check the transmission range selector switch closely, inspect the harness and do a wiggle test on the wires. some how your wire are disconnected
