Updated Jun 29, 2020
P0742 SATURN code possible causes
- Low manual fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open up or shorted
- Transmission internal mechanical problem
How practise I ready code P0742 SATURN code?
Cheque the "Possible Causes" listed to a higher place. Visually inspect the related wiring harness and connectors. Cheque for damaged components and look for broken, bent, pushed out, or corroded connector'due south pins.
P0742 SATURN code tech notes
When a transmission solenoid is stuck on, in virtually cases the problem is non the electrical part of the solenoid; the trouble is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very muddy, it is recommended to change the manual fluid and if possible removing the manual pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that at that place is a manual mechanical failure and that the transmission will need to be rebuilt or replaced.

When is the P0742 SATURN code detected?
When the Powertrain Command Module (PCM) no longer provides a ground path, the Torque Converter Clutch (TCC) solenoid valve de-energizes and utilize fluid exhausts, releasing the TCC.
When the PCM detects low torque converter sideslip when the PCM commands the TCC OFF, and then is sets the P0742 code.
What are P0742 SATURN lawmaking possible symptoms?
- Engine Low-cal ON (or Service Engine Soon Warning Light)
P0742 SATURN code description
The Torque Converter Clutch (TCC) solenoid valve is a normally-open exhaust valve that is used with the Torque Converter Clutch Pulse Width Modulation (TCC PWM) solenoid valve in society to control fluid acting on the converter clutch apply valve. The TCC solenoid valve attaches to the manual case assembly extending into the pump cover. When grounded (energized) past the Powertrain Command Module (PCM), the TCC solenoid valve stops converter indicate oil from exhausting. This causes converter signal oil pressure level to increment and move the converter clutch apply valve confronting spring force and into the apply position. In this position, release fluid is open to an exhaust port and converter feed fluid fills the apply fluid circuit. The converter feed fluid applies the TCC.
