Help with Diagnosis/Codes

[vcruz2345]

Ok, here it goes. I just got the readings from the scan and this is what I got:
122: TP Sensor signal too low
157: MAF Signal too low

Transmission:
566: 3/4 Shift Solenoid/Circuit
629: Torque Converter Clutch Circuit Fault

Can anyone help with remedies for each problem. I would like to know if simply changing the TP and MAF will correct a low signal problem or if it's something else? Can I clean the MAF? What about the TPS? As for the tranny issues I have no Idea, I am Tranny illiterate. Help me out guys!!!!!

For the TP Sensor, check the wires.. make sure the connectors are clean. Spray 'em down with some carb cleaner, electrical parts cleaner, or the like.
Same with MAF.. also try cleaning the MAF itself.
If none of that works, they may need replaced. But I think solving the TP sensor may also fix the MAF code.

no clue on the tranny ones, tho

The repair manuals usually say to repair the first code, clear the codes, then test drive and run the codes again to see if any of the others recur.
If you keep getting them, the transmission codes probably indicate a bad connection/broken wire in the appropriate circuits.

Thanks a lot guys, that helps alot.
Hey, I tried driving today and my tranny wouldn't shift out of first. Hope it is a bad wire, could mean it completely cameoff or something.
