This is for the TCC Solenoid Stuck in the Off positions. Could be a bad solenoid or a blown fuse.

SOURCE: 1999 saturn sl2 5 speed transmission will not

There is no 'adjustment' but you can check your linkage for security making sure nothing is loose or worn. Also check your fluid levels. If reverse is completely out and your starting to lose second you will probably need to have the transmission rebuilt or replaced.

SOURCE: 1999 saturn sl2 transmission wont shift from 1st gear

Your valve body and possibly input shaft nut need to be replaced. The valve body's booster valve is worn down and won't create pressure. Before it went completely out it slammed on the input shaft nut and loosened it.

You need to replace the valve body and retorque the input shaft nut. The transmission is not junk. The above needs to be replaced and change the filter and fluid and do it every 20K miles.

How to fix


P0741 Torque Converter Clutch Circuit Performance or Stuck Off OBD-II Trouble Code Technical Description Article by Dan Weller ASE Certified Master Technician Torque Converter Clutch Circuit Performance or Stuck Off This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model. What does that mean? Modern vehicles equipped with automatic transmissions / transaxles use a torque converter between the engine and transmission to increase the engine torque output and drive the rear wheels. The engine and transmission are actually connected by a fluid coupling mechanism inside of the torque converter which is what multiplies the torque until the speeds equalize and create a "stall" speed where the difference in actual engine RPM and transmission input RPM is around 90% efficient. Torque converter clutch (TCC) solenoids commanded by the Powertrain control module/Engine control module (PCM/ECM) or the Transmission control module (TCM) to direct hydraulic fluid and engage the torque converter clutch to create a solid coupling and increase efficiency. The transmission control module has detected a fault with the circuit that operates the torque converter clutch solenoid. Note: This code is similar to codes P0740, P0742, P0743 and P0744. There may be other diagnostic trouble codes associated with the transmission control module that can only be accessed by using an advanced scan tool. If any additional transmission related DTC's appear in addition to the P0741, an electrical failure is likely. Symptoms 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 Potential Causes Causes of this DTC may include: Wiring harness to transmission shorted to ground Torque converter clutch (TCC) solenoid internal short Transmission control module (TCM) Diagnostic Steps for P0741 DTC Wiring harness - Check transmission wiring harness for damage or loose connections. Use a factory wiring diagram to locate the appropriate power source and all connection points between circuits. The transmission may be powered by a fuse or relay, and triggered by the TCM. Disconnect the transmission harness at the transmission connector, power source and TCM. Check for a short to ground inside the transmission internal wiring harness by locating the appropriate + and - pins for the torque converter clutch solenoid. Using a digital volt ohm meter (DVOM) set to ohms scale, check for a short to ground in the circuit with the positive lead on either pin and the negative lead to a known good ground. If resistance is low, suspect a short to ground the internal harness or the TCC solenoid - removing the transmission oil pan may be necessary to further diagnose the TCC solenoid. Test the wiring between the TCM and the wiring harness connector at the transmission case using the DVOM set to ohms. Check for a possible short to ground by moving the negative lead on the DVOM to a known good ground, resistance should be very high or over limit (OL). Torque converter clutch (TCC) solenoid - Check the resistance in the TCC solenoid and internal transmission wiring at the transmission case after removing the transmission harness plug (if applicable, some makes/models use a TCM bolted directly to the transmission case). Some makes/models use a transmission wire harness with the TCC solenoid and internal harness as a single unit. Using the DVOM set to ohms, check for a short to ground with the positive lead on either circit to the TCC and the negative lead on a known good ground. Resistance should be very high or over limit (OL), if it is low, suspect a short to ground. Check for voltage on the power side circuit of the TCC solenoid or at the wire harness connector at the TCM with the DVOM set to volts scale, positive lead at the wire being tested and the negative to a known good ground with the vehicles key on/engine off, battery voltage should be present. If no voltage is present, determine the loss of power back through the circuit using the manufacturers wiring diagrams for reference. Transmission control module (TCM) - Since the torque converter clutch is only activated during certain driving conditions, it will be necessary to monitor the TCM with an advanced scan tool to determine if the TCM is commanding the TCC solenoid and what the actual feedback reading is at the TCM. The TCC solenoid is normally controlled by a duty cycle to engage a more comfortable torque converter cluch engagement. To test if the TCM is actually sending the signal, a graphing multimeter set to duty cycle or a digital storage oscilloscope will be required as well. The positive lead is probed into the wiring harness plugged into the TCM and the negative lead to a known good ground. The duty cycle shold be the same as being commanded by the TCM in the advanced scan tool reading. If the cycle stays at 0% or 100% or is intermittent, re-check connections and if all wiring / solenoid is OK, the TCM may be at fault.

Do you have the error code (P0742 = torque converter clutch stuck on...locked and P0741 TCC stuck off). The TCC solenoid replacement for the 4T40E (and 4T45E) is not very expensive but the job of getting the transmission case out from the car is difficult. Unless you have experience of fixing transmissions this is best left to an expert.

My Ford Focus 2006 4 cyc has an engine code PO741 on my OB2. What does that mean?


P0741 Torque convertor clutch circuit failure,it is located in the transmission valvle body, it is attatch to the valve body you can remove it seperately as long as your going to own the Ford focus you might as well get use to replacing these all the time,very common transmission issue with todays car. By the way it is sensitive to worn transmission fluid,when you dont service often these are suspectable to failure.

CODE P0741


P0741 "Torque Converter Clutch Solenoid stuck off"
If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. The Powertrain Control Module (PCM) controls the Torque Converter Clutch Solenoid Valve (TCC Sol. Valve) Pulse Width Modulation (PWM). The solenoid controls the hydraulic fluid for TCC apply and release. When the TCC is applied, the engine is coupled directly to the transmission through the TCC. The TCC slip speed should be near 0.

Transmission issue? Or worse?


Hello! Although the symptoms you've described could be a result of quite a few things, I have a few questions that might help determine your problem.

1) What year/make/model did the new transmission come from?
2) Is the SES (Service Engine Soon) light on? Is it blinking?
3) Was this transmission a rebuilt or used unit?
Some possibilites:
- you could have a faulty TPS - or Throttle Position Sensor.
- you could have a problem with the input shaft piston being worn. (Hence the used vs. refurb trans question). Once the inner sealing area wears it can prevent the inner lip seal for the piston from sealing properly. You may find that revving the engine up will finally get the car to move and it will BANG into gear. This is because the pump in the transmission is working harder and moving more fluid thus allowing the added fluid to overcome the leak which prevented the clutch from either initially applying or staying applied. Another area of concern that causes this is a boost valve in the valve body, not near as common but it can cause this problem on a lessor scale.

- Trouble Code P0742 TCC Stuck ON:
When this trouble code is set the pcm will command max TCC and lock adaptive shifting. This code can be broken down into three potential problem areas as found to be common in the field.

1. This problem can be a mechanical problem. Possible causes of this could be a bad or stuck TCC switch that signals the pcm of current TCC operation. Another cause though not common is a stuck TCC switch or apply valve. If it is physically stuck in the wrong position it can cause the TCC to be stuck on all the time and even kill the engine when the vehicle is put into gear.

2. This problem can be found to be an electrical problem. If the wire from the TCC pressure switch to the pcm is grounded anywhere in the path it can throw this code. This could be a wire shorted inside the trans on the internal wiring harness or the actual engine wiring harness. If the wire is grounded the pcm thinks that TCC is on when it shouldnt be and will throw the code.

3. This problem can be a hydraulic problem. This is the most common cause of this code that I have found and stems back to a clogged TCC solenoid, not because it failed. Excessive debris in the transmission or a failing torque converter lockup clutch can cause the solenoid to have debris stuck inside and this causes a restriction in fluid flow through the solenoid. If the solenoid can not bleed off the pressure the TCC can be stuck on. If the wrong TCC solenoid is installed during an overhaul this problem can also arise as a late 4L60E solenoid is identical but does not operate the same and acts like a clogged solenoid. As mentioned in problem #1 a stuck TCC apply valve is a physical problem but causes a hydraulic problem because the fluid pressure will not properly bleed off because the valve is stuck in the wrong position instead of being able to move freely in the bore of the valve body.
Above are the common causes of this code, there are other possibilities but those are what generally causes the fault. A thorough diagnosis is the only way to determine what is really at fault and a new TCC solenoid should never be assumed as the actual problem until verified.
