P0740 code error

Have a 2011 unlimited 3.8 and keep getting a P0740 code error. I was told to change both the valve body and the vehicle's torque converter. As this is too expensive, are there any other reasons I could be getting this message? So far, there is no change in the car's performance/noise.

Could be as simple as a dirty connector. Might affect your gas mileage due to less torque converter efficiency.

These links look interesting:

Thanks! I'll look into it!
So far no problems with milage. Just my battery died yesterday... don't know if it has to do with the error I'm getting
