Question about 2004 Toyota Corolla
I followed you advice regarding driving my car 2004 corolla that had it's cat coverter, and solenoid replaced but the check engine light is still on. You asked that I get back to you once I drove the car after repairs, so it could go through it's cycles. Well it's 200 miles later and I am following up on the March 16, 2010 request. What else should be done - I still have the same diagnostic code of - P0741.
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.
