Well, the solenoid was definitely part of the problem. At any stall condition, with the transmission in gear and the engine running but the turbine standing still, the fluid is reversed by the turbine vanes and pointed back to the impeller. The low coolant is probably due to a crack int he expansion tank where you add coolant. P 0741 - Torque Converter Clutch Circuit Performance or Stuck Off Read more: 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 - Transmission internal mechanical problem When is the code detected? In some cases, merely topping off the fluid level or replacing the fluid will resolve the problem, but be aware that replacing or topping off the fluid is not guaranteed to resolve this code. The rotating impeller acts as a centrifugal pump. The only way to know for certain is to follow the diagnostic procedure as outlined by General Motors.
Some extremely popular vehicles such as the Cavalier and the Grand Am also use this transmission. Since some of these tests require the drive wheels are raised off the ground and the engine and transmission run in gear, proper care must be taken to perform the tests in a safe manner. Brought it to the dealer and he couldn't read it either. But the p1783 is tran overheat condition. What are the symptoms of code P0741? This information can be very useful should an intermittent fault be diagnosed later on. I yanked my Superchip just before carlsie 03 and at Carlise it blew up.
In this case a check valve seats to allow the line pressure to build up as stated above. In some cases, it might be necessary to allow the fault to worsen before an accurate diagnosis and definitive repair can be made. Only one wire should now be hot. If the scanner confirms that the solenoid is indeed reacting correctly, continue to activate it several times to see if it fails to react on some input cycles. Elite Explorer members see practically no ads, can add their own profile photo, upload photo attachments in all forums, and Media Gallery, create more private Conversations, and more. Good luck Aug 27, 2010. This can cause the vehicle to buck and stall when approaching a stop sign.
See test 13 Go test 7. The computer system has a self-diagnostic capability. If the actual measured pressure falls within specifications, proceed with the electrical diagnosis. Visit the homepage for more information about what other types of auto repair information we cover. If the code does not return after a few complete drive cycles, the repair can be considered successful. I would recommend stopping at a local transmission shop and let them tell you your options.
Have your radiator, which also has a transmission cooler flushed, cleaned and refilled immediately. Without the stator, any momentum left in the fluid after it leaves the turbine would resist the rotation of the impeller. The torque converter clutch is supposed disengage when you step on the brake pedal. If it does not flash a code 12, refer to the car's service manual for further tests. The latter is bad in the long run since I have been told that the big killer of the transmission is heat.
However, to prevent engine torque from overcoming the shear strength of the transmission fluid in the torque converter, or to prevent excessive torque from damaging transmission or other drivetrain components, the system is also designed to allow some slippage to occur under certain conditions, such as severe acceleration. I just bought a 96 Taurus Vin U with 122K miles. I assume that mine was a bit gummed up or something. This does not mean that there is no malfunction. Step 7 If there are no fluid leaks present and the transmission is hot, clear all codes and operate the vehicle for at least one complete drive cycle with the scanner connected to see if the code returns.
Lock-up piston operation will then be controlled. The most common problem associated with this transmission remains issues with the solenoid. Torque converter clutch solenoid This was not a scientific test and if the solenoid was permanently stuck applied it would not tell you what was wrong with the car. What are the common causes of code P0741? This will repeat two more times. Contrary to what I have said before, this doesn't mean certain doom for the transmission, provided the reason it occurred is not repeated towing a trailer, high speed driving, long uphill grades, etc. This is why I wanted to discuss it a little further. All of the sensors that send information to the computer are assigned a two-digit trouble code.
And it definitely keeps slipping. If the solenoid fails to work even once, there is likely to be an intermittent fault present, which can be extremely challenging to find and repair. I did touch on the operation and the basic principles behind how the converter clutch works on my page about the if you want more information. You then have a place to start looking for the malfunction. What are my options for repair full rebuild, or just minor parts replace? The impact of the moving fluid on the turbine vanes exerts a force that tends to turn the turbine in the same direction as the impeller rotation. Also, it was recorded about 2 years prior to the upload.
Hold the rubber hose in your hand. To get maximum force on the turbine vanes when the moving fluid strikes them, the vanes are curved to reverse the direction of flow. Disconnect the solenoid from the rest of the wiring, and test it for resistance and continuity. The 1 Ford Explorer enthusiast resource on the Internet since 1996. They used this very popular transmission across the General Motors product line for years. Inspect this wiring for any signs of damage or problems that could cause short -, or open circuits.
Also, there is the possibility of a physical obstruction or an auxiliary valve body cross leak. Note: some transmissions, like the 125C, must shift to 3rd before the tester will light. It is likely they were aware of the transmission problem and simply cleared the code thinking it would make it past the warranty and it didn't. This box will disappear once registered! Repair all leaks before test-driving the vehicle to prevent possible damage to the transmission. Well low and behold, it threw a P0741 code.
