Do a search over on the Olds silhouette forum and the Pontiac transport, as well as here. The first being either the 'crank shaft' or the 'cam shaft' position sensor. Water can leak into the connector from clogged sunroof drains, A-pillar leaks, or windshield or cowling leaks. Thanks for all your help. Then I go back in drive, and it is fine for a few weeks etc.
My only concern is being stranded where the car won't even drive. It also gave me some freeze frame data of some of the engine parameters at the time of the dtc set. I've gone through this with three vans, all '99s. I researched these codes, but am not quite sure which sensor is. Note that this code only applies to applications with automatic transmissions, and that the failure, defect, or malfunction could refer to electrical, mechanical, or hydraulic issues. On the road car acts like it is missing sec g. Also I noticed when I run the van the fluid level does not drop and it does not even seem to heat up at all.
What are the common causes of code P0742? The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. I am wondering if this may be a motor mount type of problem or something else. If a failure of the actual torque converter lock up clutch is suspected, the wiser option would be to refer the affected vehicle to the dealer or other competent repair facility for professional diagnosis and repair. I have done nothing except make sure the fluid is clean, and up to level. I'd like to re-seat it.
The image above shows the typical layout of a torque converter that incorporates a lock up clutch. It does not do this now. I have a strange problem you might be able to help me with! The rest of the shifting is very smooth. Recommend you get code cleared at Auto Zone, O'Riely, Advance Auto they probably won't charge you and see if code comes back, it may only be a one time incident. Before installing the drive sprocket, lubricate the bearing assembly with J 36850 assembly lubricant. Mi respuesta fue la 2da opcion por lo rapido y lo cansado que estaba de esa falla. You should find many, many posts from myself and many others detailing this issue as its pretty well known for the vans from '99 thru 2003.
By modulating the hydraulic pressure that keeps the torque converter clutch engaged, the transmission is protected against damage caused by excessively high torque inputs. The computer is giving me a P0742 code. It is unrelated to miles driven, ambient or operating temperature, or time. The transmission shifts beautifully through all gears, all of the time. Mañana iré con mi electrico para que lo instale de forma definitiva para operar al abrir la llave. Ways to clear check engine light on car panel. I dropped the pan and put in new filter and fluid ect and it did not help.
I also have a code for the Mass Air Flow Sensor and Catalyst Efficiency which I think is related to other things. If the lock-up clutch is engaged, it functions in exactly the same way as a clutch on a manual transmission, in the sense that it provides a solid mechanical link between the engine and the transmission, thereby eliminating any slippage between the two halves of the torque converter. You could check to see if the pump was doing anything by pulling a transmission coolant line loose from the radiator while the van was running in park. Hope help with this remem,ber comment and rated this. I reposted it with a more descriptive title: Updated info: 130k miles. I'm afraid to tell you this sounds like the time to pull the tranny out for rebuild.
. The problem is that the vehicle will move when placed in reverse, but not any forward gear. Update: car now has 146k on it. No volvio a presentar la falla. If all the components in the system work as designed, the driver is unaware that the system is functional; however, if a failure, defect, or malfunction anywhere in the system prevents the torque converter lock up clutch from disengaging, the result is serious drivability issues because the engine cannot be decoupled from the transmission. These were a common failure in G. I am truly hoping that you wizards out there will tell me there is still more that I can try and that I don't need a new tranny.
Les aviso entre el 27 y 28 de Julio 2011. Or could it be external? When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. If that does not fix the problem I would change the converter. ? You gotta spend the bucks at a tranny shop. Could this cause this issue? This one works great except for this new issue. Por supuesto, tengo mas de 3 meses que no voy. If it comes back then it will need to be repaired.
En un foro americano, dicen que es problema de esas transmisiones d elos años 99 a 2003. Comparto esta solucion porque sufri muchos años con esa falla y se lo que se siente, frustracion. Mi carro cavalier 98 automatico presentaba esa falla desde hace mas de 8 años, lo lleve a un mecanico y me cambio todos los sellos y discos de la caja sin resultado positivo. The other issues you mention are not related. Si no resuelvo el problema de raíz, espero no de la patada. Acts like missing sec gear Code P0742 Torq conv. No la he probado mucho tiempo, pues el trabajo me tiene atado.
