I have a 98 venture that has developed a bad misfire. I scanned it and all 6 are misfiring at different times. You can be driving and try to hold a speed and it goes to misfiring. Speed up quick and the misfiring goes away. Tested ignition mod. and orielly says it is ok.

ok my husband wrote on here before about misfiring and codes.. he checked all the spark plugs got the transnmission cleaner stuff.. and its still misfiring.,.. my friend cleared the code for me and it came up with a 742 code... does anyone know what that is? it seems to misfire off and on every few weeks runs like its gonna die when you are going between 0-55 mph... once you get above that it stops but the service engine light soon is still on..... any ideas would be great! i love my van just need it to run right?

Replying to: trinak (Jun 24, 2008 6:53 pm) Well, I tried to find a more specific thread in which to respond to this question, but couldn't so I'll respond to it here and then perhaps if there is any further discussion someone can find a more relevant thread where this problem can be discussed and perhaps already has been discussed: Possibilities: Failure of the Torque Converter Clutch (TCC) Solenoid, the 2-3 Shift Solenoid and the Transmission Valve Body. If its the TCC solenoid then it will be 85.00 for parts and probably 300.00 for labor. Transmission Valve Body would be a bit less for parts but a good bit more in labor. Good luck to you.

Replying to: trinak (Jun 25, 2008 11:00 am) I'd start with the fusebox and make certain 5, 11 and relay31 are fine. Look up the diagram to confirm which ones are TCC related incase its 33 rather than 31. If this is normally a 300.00 in labor job, I would hazard a guess that the tcc solenoid is not all that accessible. I've heard that a faulty tcc can cause damage from excessively hard shifting due to clutch slippage being detected by the pcm. With the high potential for transmission damage if driven like this for long, some shops may be unwilling to just install a new solenoid and then have to face potential complaints. So act promptly if possible. I really do NOT know much about this and you should find another thread that deals specifically with transmission shifting on a Chevy Venture or atleast someone who knows what he is talking about.
