Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / October 200799 Malibu Problem
I have a 99 malibu 3.1 L V6 engine that has a problem.The check engine light came on and we had the code pulled and it came back P0742.I was told it mostly meant the TCC was stuck on.Is that right? Also I was told that I could unhook the TCC Solenoid and still be able to drive my car without causing any damage to the transmission is this true? Thanks in advance. > I have a 99 malibu 3.1 L V6 engine that has a problem.The check engine > light came on and we had the code pulled and it came back P0742.I was > told it mostly meant the TCC was stuck on.Is that right?

Without being at my shop to look up the code, I couldn't say exactly what the code definition or conditions are, but a P07xx code is a transmission code. Most newer electronic transmissions (like yours) don't have a plug-in just for the TCC (torque converter clutch) so "unhooking" is not a particularly viable option. You could unplug the transmission, remove the TCC signal wire, tape it off to prevent it from shorting out against the transmission, and plug in the connector again, but torque converter lockup is critical to maintaining transmission fluid flow to the cooler during overdrive operation (when you select OD, or just D on some transmissions, your selector may show P R N OD D 2 1 or P R N D 3 2 1) and without the TCC you could seriously damage your transmission.
