There are two modes of operation involved. This problem finally manifested itself long enough for me to do some trouble… It Begins as a series of buttons that need to be pressed and held at the same time. Keep in mind that the transmission pan may have to be dropped to get to all of the wiring. Compare the obtained reading to the value specified in the manual, but take note that there are no quick or easy fixes for low transmission pressure problems, and especially if the transmission has a life-time fill. If the code does not return after a few complete drive cycles, the repair can be considered successful.
How serious is the P0741 code? Don't know if you are a pro or not, but this is not something that can easily be troubleshot by the average home mechanic due to the complexity of the systems involved, the electronic test equipment required, and knowledge there of. Are you looking for code P0741 troubleshooting help, code P0741 diagnosis tips, code P0741 diagnostics or code P0741 technical information? And lets face it, if the service engine light is on then you need it now! The transaxle gear ratio indicates 2nd, 3rd or 4th gear. With P0741, the code gives you two reasons as to why the code has registered. Just made this replacement last week on a 98 Deville. The transmission fluid temperature is 68-271 F 20-133 C.
If not, perform the transmission fluid checking procedure. The turbine shaft seals are worn or cut. Although the actual parameters that set code P0741 vary greatly between applications, the basic operating principles and purpose of the torque converter clutch remain the same in all cases, which is to provide a solid link between the engine and the transmission, much like a conventional clutch locks a manual transmission to the engine. Allow the transmission to reach operating temperature by monitoring the transmission fluid temperature with the scanner, but cycle the transmission through its full range of gears including reverse to make sure that fluid is circulating properly. P0741 is a very common trouble code. The problem involves the fact that these transmissions usually have no provision for draining the fluid, but worse, the volume of fluid required to fill the transmission is a detail that car manufacturers choose not to share with the independent auto repair trade.
It is purely a transmission related code. With this information you can easily determin what system to trouble shoot without knowing the exact description of the code. Move drivers seat all the way forward, remove 2 bolts at rear of track, allowing seat to be tilted forward.

The engine torque is 32-159 ft. Step 1 Start the diagnostic procedure by checking the transmission fluid level, as well as the condition of the fluid. A complete driving cycle will perform diagnostics on all monitored systems and can usually be completed in less than fifteen minutes. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed. Compare all obtained readings with those stated in the manual; note though that all values must conform to stated values exactly. 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. This is type of transmission repair is generally beyond the knowledge level of the average do-it-yourself home mechanic, and is probably best managed by an experienced transmission repair technician.
Here is how we suggest you proceed. If not, go to next step. 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. How do you troubleshoot code P0741? These are listed in numerical order for easy searching. Step 2 If the transmission fluid appears to be serviceable and up to the correct level, record all codes present, as well as all available freeze frame data.
With P0741, the code gives you two reasons as to why the code has registered. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run. To display stored codes: 1. The wiring should be the first place that you should check, as it will most likely be the problem. Remember, these are manufacturer specific codes only.
Updated through the 2004 model year. The engine torque is 32-159 ft. Take note that the actual converter clutch solenoid forms a part of the circuit, and it must therefore be tested as well. Also, the dimmer wire may not be brown, but may not matter as most aftermarket systems don't use it anyway. In some cars, the transmission pan will need to be dropped and if this is the case, make sure the transmission pan is dropped properly.
