Got code P0743, indicating "torque converter clutch circuit electrical." Looked at a couple of sites, including a Toyota site that indicated serious troubleshooting to determine if problem is ECM, shift solenoid valve, or harness/connectors.
I'm not into heavy maintenance, i.E, going into the transmission to check/change valve.
BTW, what's the ECM?
have the same problem?
