My lockup torque converter is not working, once it warms up. I am also getting a P0740 code. I have found some diagnostics on the web to check the relay and wiring, but I don't know where the relay is. Can someone tell me where the relay is on a 98 Tracker??? I am guessing it is the solenoid, but I wanted to check circuit first. The only other thing I have done was change the fluid and filter, and it wasn't that dirty.

Thanks in advance, Luke
