Does P0741 mean a real transmission issue and/or ECM problem?

Just take car to AutoZone to use their Diagnostic Code Reader and then they can look it up and tell you what is wrong and part that you should replace.

P0741 torque converter stuck off code - 2004 Toyota corolla

P0741 deals with internal transmission torque converter slip. A proper scan tool that is capable of reading the sensor's data inside the transmission would show the slipping torque converter and the fluid temperature.
It is critical to know exactly what conditions are present when the code stores. If the codes were not erased, they could be old codes in it's history.

Go back to the transmission shop or where you had the work done on replacing the TCC solenoid and have them read and clear the codes history. As mentioned, they could be old codes that is being read prior to your repairs.
Thank you for using Fixya and good luck, Have a shop verify line pressure, and provided no valves in the TCC hydraulic circuit are worn, replace the torque converter. Also, Lubegard Shudder Fix will at least fix this for awhile. Or try a transmission flush by a shop that uses BG brand products.

03 toyota corolla engine light on again!

Without seeing your vehicle on my scan tool, it is hard to see what is exactly going on.
But, please allow me to share the following info with you:
The P-0171 code relates to the Mass Airflow Sensor. This is a VERY common code with the Corolla product.Your dealer *** should *** have inspected it for dirt contamination, and cleaned it, if it was indeed dirty.
Secondly, The P-0125 relates to Oxygen Sensor number ONE. If your dealer replaced the wrong sensor; (#2), you can expect to have problems.
My advice: unplug, remove, inspect & clean the MAF sensor. Ensure that the air filter is clean.
This should help you quite a bit.
