Default 94 ssei Code P0740 TCC Circuit.

I have a 94 Bonneville SSEi with 132,000 miles and throwing a code 740 Torque Converter Clutch Circuit. Should I replace TCC Solenoid? Should this have the 4T65E trans or not for 94? Thanks

That code could be for alot of reasons. A short, bad wire, bad connector, bad PCM, etc etc.

You have the 4T60E, not the 65.

Is this the connector at the top of the trans toward the front?

Thanks
