Can Toyota Diagnose Transmission error Code P 2757 without tear down?

I have a 2010 Toyota Corolla LE 70,000 miles.... Can the Toyota dealership, or Transmission shop diagnose the actual problem with error code P2757 related to the Torque Converter Clutch Pressure Control Solenoid Circuit Performance Stuck off reading. The dealership said they needed to tear the transmission apart to find problem. I do not believe them. I have been told by other mechanics that their computer testing equipment should be able to detect which solenoid is out. can a single solenoid be replaced if it can be detected? Please help and advise.

Sir base on my experience as toyota technician i agree to teardown your transmision.we have same cases here after we open the rear side of transmision cover we have found that overdrive clutch and plates is burned out and even we replace the said shift solenoid valve and worn out disc and plates but still you cam feel the sudden shiftshock.so we decided to make overhaul ..

No post since 2016. Waste of time to say it is solved. If this is solved then so is The Middle Eastern Crisis!!!!

I have a 2007 IS250 and it will come up with this fault. I just keep resetting it. But I notice that if I drive it in Sports mode and don’t use 6th speed it never faults.
