What exactly is the P0741 code

P0741 indicates a concern with the torque converter clutch solenoid performance. It does not indicate any specific part has failed, more that in whole, there's a system that is malfunctioning. Troubleshooting hands on is needed to find out specifically what is going on. I can tell you that a 15 year old vehicle with unknown miles will likely require transmission overhaul or replacement; many times, a code like this is on due to multiple internal concerns. Even if you were able to replace a component that in theory could help, it would likely be short lived. Your concern is pretty significant and will require professional testing.
