Other people have reported the fault code for the lock-up torque converter when there really isn't a problem with that circuit. I've never read what the solution was other than to erase the code. It seems like it sets due to some unrelated issue.
If you want to measure the continuity of the circuit to include the solenoid itself, I put some diagrams together to show where to measure from. The best diagram I found is the last one of these five drawings. Look for fuse # 28 in the under-hood fuse box and use either of the test points on top of it. That's a blue 15-amp fuse. Blue arrow in that diagram. In the sixth drawing, fuse # 28 is listed as a red 10-amp so I'm not sure which you have.
You'll need to unplug the connector from the Transmission Computer, then use the light blue wire, (green arrow in the diagram), terminal 11 in connector C2 for the other ohm meter probe. I would expect to find around five to 20 ohms, but mainly we don't want to find an open circuit, (infinite resistance).
