P0741- Torq Conv Clutch Circ Perf/Stuck Off
Looks like the torque converter clutch circuit is in the off position causing the car to stall. But as I read this again I can see you know that. I would check or change the tcc switch on the tranny to start. I believe it is on the rear of the tranny.

Automatic ford ranger it starts then when you put it in gear it stalls.


One of the most common failures that can cause this problem that I have seen before is the Torque converter solenoid (TCC solenoid). This solenoid can stay stuck on and cause the torque converter to stay locked up, this will cause the vehicle to stall whenever it is put into gear. The vehicle will start and run fine in park or neutral but will stall out as soon as it is put into gear. This is the most common failure that can cause this.
Also a malfunctioning idle air control valve can cause this, if the valve isn't moving or responding to bump up the idle when put in gear it may cause the vehicle to stall out, the computer commands this valve to allow more air in to bump up the idle to compensate the load on theenginewhen put in gear, if it isn't moving or isnt moving fast enough the idle may be too low and could cause the engine to stall out.Have also seen bad crankshaft position sensor cause this ,as well as mass airflow sensor's ,TPS - throttle position sensor's . Your best bet , take it to a qualified repair an have it diagnosed . No guess work .

Dashboard code puller on a 2004 Caddy Deville: U 1016, B 1860 and P0741 codes. Changed oil and exchanged trans fluid. I drove about 120 miles the service light came back on. Code P 0741 can back.


What year ?
If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. DTC P0741 is a type B DTC.
The powertrain control module (PCM) controls the torque converter clutch (TCC) solenoid 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.
Diagnostic Aids
• Inspect the transmission fluid level.
• The transmission may be in hot mode. Inspect the transmission fluid lines to the radiator. The lines may be pinched, plugged or twisted.

Do you own a professional or factory scan tool ?
Install a scan tool.
Turn ON the ignition, with the engine OFF.
Important: Before clearing the DTC, use the scan tool in order to record the Freeze Frame and Failure Records. Using the Clear Info function erases the Freeze Frame and Failure Records from the powertrain control module (PCM).
Record the DTC Freeze Frame and Failure Records.
Clear the DTC.
Drive the vehicle at 72 km/h (45 mph).
Using the scan tool, command the torque converter clutch (TCC) pulse width modulation (PWM) solenoid valve ON.
Operate the vehicle under the following conditions:
• The transmission fluid temperature (TFT) is 20-133°C (68-271°F).
• The engine torque is 43-215 N·m (32-159 lb ft).
• Drive the vehicle in D4 with a throttle position (TP) angle of 10-50 %.
• Ensure that the TCC applies for more than 5 seconds.
Monitor the TCC slip speed.
During TCC application, is the slip speed within the specified parameters?

C/E light on for 1 code P0741, changed TCC solenoid, trans fluid, filter why would the transmission stop going into gear after previously shifting beautifully with no slipping or any issues at all.


Just because you installed a new part, do not assume it can't be bad. This happens alot with aftermarket parts. When you change just a minor part and a problem develops, good idea to double check both your work and the new parts.

P0507 Higher idle speed than expected partially stuck open thermostat engine running colder than normal raises idle speed. Small vacuum leak raises idle speed. sticking throttle cable holding throttle plate open.
P0741 Torque Converter Clutch system stuck off : Code conditions : No engine or transaxle system codes set, engine run time over 5 seconds , Throttle Fluid pressure switch not indicating Park/Neutral,TCC commanded On @ max duty cycle, throttle angle over 8% Trans fluid Temp input 68-248f Degrees not in fuel cut off, trans gear ratio indicates 2nd, 3rd, 4th gear delivered torque 32-150 ft lbs, the PCM detected a TCC slip value that was over the torque limits . most likely cause is bad tcc solenoid or torque converter itself.

PO744 code 2001 infiniti qx4 how do i fix


CODE PO744 AUTOMATIC TRANSMISSION TORQUE CONVERTER CLUTCH SOLENOID VALVE FAULT. POSSIBLE CAUSE FAULTY TCC SOLENOID.CHECK TCC SOLENOID WIRING FOR DAMAGE.OR YOU COULD HAVE FAULTY TCM OR ECM. IF THE TCC SOLENOID IS FAULTY YOUR ENGINE WILL STALL OUT AT A RED LIGHT OR STOP SIGN.YOUR ENGINE WILL STALL OUT AT EVERY STOP THAT WOULD BE SIGN FAULTY TCC SOLENOID.IF ENGINE DONT STALL OUT THE TCC SOLENOID COULD COULD BE STUCK OPEN, IF YOUR TORQUE CONVERTER FAULTY IT WILL CAUSE PREMATURE LOCKUP STALLING OUT THE ENGINE.

01 Buick Century Custom with a 3.1L . I have a code po741 or p0741 it says the troque converter circuit is stuck on what can i do to fix this .


P0741 TCC STUCK OFF If the PCM detects high converter slip when the TCC is commanded on, then a DTC P0741 will set. The following conditions must exist for two times during the same ignition cycle. This code will set for all the same reasons that a P1870 will set: • The TCC duty cycle is greater than 50% • The TCC slip speed is greater than 180 RPM for 7 seconds • TCC slip in 3rd gear on 4L80-E transmissions Known causes for P0741: • Worn TCC valve bores in the valve body • Damaged or worn pump bearing seal • Defective TCC PWM or TCC apply solenoids • Restricted separator plate solenoid feed orifice • Defective converter • Computer reprogram • Channel plate sleeve & turbine shaft sealing ring damage I would suggest changing fluid and filter & reset pcm.

1.car stalls out when you put it in gear, mainly reverse. 2.jerks and stalls when starting forward..A4..1.8T 2002 audi 1.8 turbo L4 FI 20V 112,000 miles


Sounds like your TCC (torque converter clutch) solenoid is causing improper lockup, causing the engine to stall. It works similar to putting your hand on a ceiling fan to stop the blades. I believe this is where you will find your problem.

Good Luck!
