What does DTC code p0741 stand for?
What Does the P0741 Code Mean? Diagnostic trouble code (DTC) P0741 stands for “Torque Converter Clutch Solenoid Circuit Performance/Stuck Off.” To put it plain and simple, code p0741 triggers when an onboard computer, referred to as a control module, perceives a problem with the operation of the torque converter clutch (TCC).
What does trouble code p0741 mean on GMC Sierra?
It is purely a transmission related code. Although, the engine response may “feel” different without the torque converter locking. The vehicles PCM (Powertrain Control Module) will throw the P0741 trouble code in the GMC Sierra if there is a difference that is greater than 200 rpm between the transmission input shaft and the torque converter speed.
When to use the p0741 clutch solenoid code?
Applying the TCC improves fuel economy, reduces engine speed, and lowers the temperature of the transmission fluid. The control module may store a P0741 code when it detects the TCC is slipping, operating erratically, or not engaging.
What are the symptoms of a stuck p0741?
If any additional transmission related DTC’s appear in addition to the P0741, an electrical failure is likely. Symptoms of a P0741 trouble code may include: Performance or Stuck Off Indicator Lamp (MIL) illuminated (a.k.a. Check Engine Light) Minimal decrease in fuel economy, this will not affect engine performance

What does the p0742 code on a torque converter mean?
The P0742 code indicates that the torque converter clutch circuit is behaving in an abnormal manner. When the P0742 code appears, it means that the amount of torque converter lock up required is not in line with the amount that is actually detected.
Are there any symptoms associated with the p0742 code?
Symptoms associated with the P0742 code can vary substantially. With some vehicles, the driver might not detect any issues at all. However, in other cases it will no longer be possible for the torque converter clutch to disengage.
What does the trouble code p0742 mean?
Meaning, the torque converter clutch circuit is performing abnormally, which usually happens due to dirty transmission fluid or valves. This code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system or vehicles made since 1996 up to present.
What causes a torque converter clutch code of p0742?
The P0742 code can be caused by a variety of things. The following are the most common: Dirty transmission fluid. Low transmission fluid. Faulty torque converter clutch solenoid valve. Internal mechanical problem with the transmission. Torque converter clutch solenoid valve harness or connectors could be bad.
What causes a torque converter clutch to code p0741?
Note the flow path the transmission fluid takes to activate the clutch. What are the common causes of code P0741 ? The main causes of code P0741 are degraded and/or dirty transmission fluid, and wiring issues such as short circuits, open circuits, or disconnected wires.
What causes low transmission fluid level in p0741?
P0741 Possible Causes Low transmission 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 or shorted
