ghead Hey everyone!
My check engine light came on about a week or so ago. I had my mechanic look it over, and after plugging in his troubleshooting module into the OBD, he tells me that it is a fault P0740 which is describe as "P0740 Torque Converter Clutch Circuit Malfunction". Have any of you experienced this on your cars? And it is repairable w/o tearing the tranny completely? Can I replace the circuit myself? Anyone have any thoughts? My car runs about 2300 rpm's @ 65 MPH. It is a 1999 528 iT wagon, 6 cyl. automatic 4 speed. It shifts fine in all 4 gears. Thanks all! JM>
