Replying to: 442dude (Jan 17, 2008 6:59 pm) P1189 - Oil pressure switch circuit p1626 - Theft system fuel enable P1811 - Max adapter long shift. The mechanic pulled one of the plugs and we discovered that they are the original plugs. Quite worn out. I am going to change the plugs and wires this weekend to see what that does. I still don't know how the plugs or wires would only cause a problem on the highway and cause my lights to dim. Anyone with more suggestions? My ears are open. Thanks

Replying to: mudder1_2000 (Jan 19, 2008 8:24 am) P1626 is a problem with your theft deterrent system...basically, there is an intermittent problem with the serial communications between the powertrain control module (PCM) and the body control module (BCM) This is also not causing your hesitation problem, its just a stored code that says that at least once, your car had trouble verifying that the correct key was being used to start it. If this was your problem, the van would start, run for 2 sec. and shut down. I wouldn't worry about this one... P1811 - the long shift code is typically set when your pressure control solenoid is going bad in your transmission. About a $ 600 repair, its internal to the trans and an all to common failure on the Venture (and on the 4T65E trans in general) The typical symptoms are harsh shifts at all speeds and a loud whine when the trans gets hot. You don't mention either so I'm guessing its not your problem. It may be as a result of your actual problem. I don't think any of these 3 are indicative of what's going on. Without driving it I'm still thinking fuel or ignition issue. Change your plugs and wires like you said you were going to do and also change your fuel filter. Be prepared to let out a string of expletives as you try to get to the rear plugs... Also make sure that the terminals on the coils are squeaky clean when you replace the wires and coat them lightly with dielectric grease before you put on the new wires, you'll have to remove them to get to the rear lugs anyway so its a good time to check them out - if you've got a multimeter, check the resistance between the two towers on each (towers meaning where the wires connect to) the resistance should be 5000-7000 ohms - if its above or below, you've got a bad ignition coil...Hopefully you'll get rid of your problem...good luck

Replying to: krobanker1 (Apr 14, 2008 5:34 pm) I am not a mechanic unless there's a shade tree and some beer around  That being said, couple of suggestions - -Chances are, the pressure control solenoid inside your trans is failing causing the bumping shifts and whining noises. Any competent trans shop can make this repair - expect $ 600-900...and yes, it tends to get worse as the weather gets warmer... - Are you a gambling person? Try this...go to the auto parts store and buy "Lucas Transmission Fix" put 1/2 bottle in and wait 2 weeks...your problem might go away...strangely enough, that's how I got rid of it on mine and it was completely by accident... NOTE: it will get worse for the week or so right after you do it and you will say "I can't believe that I listened to that guy on the internet!!!!" but then it might even go away. That was 2 years ago, haven't had to worry about it since and my mechanic told me I needed a new transmission when it first started happening 3 years ago...Worst case...you wait a couple of weeks, it doesn't go away and you bring it to the trans shop for the solenoid repair...Good luck

Replying to: fleastiff (Jun 30, 2008 1:33 am) Why add only a HALF bottle of it? - Because that was what I had left in the bottle when I did it? Actually, it says on the label that you should only use 1/2 a bottle for smaller transmissions. I don't know if the trans in the Venture qualifies as small. Are there any risks to using this product? - Says on the label that its good as "preventative maintenance" so you can put it in a perfectly OK trans without a problem. You may want to contact Lucas directly for more info... I'm not promoting their product...I just tried an experiment when I had nothing to lose and by chance it worked...hopefully it will help someone else too... |

Replying to: rocco7 (Nov 15, 2008 9:50 am) My own 2000 Venture started whining last night after a high speed 500 mile run on the PA Turnpike through the mountains and flat old I-70 West to central Ohio. Temps were around 28 degrees F. It was fine on the trip until I got 5 miles from home and this noise began that sounded like running on under-inflated tires. I'm going to have it checked but this transmission pressure or "transaxle pressure control solenoid" seems the likely culprit from what I've read here. |

While the solenoid is likely your problem, occasionally the MAF will get dirty and that combined with an air filter that has a little dirt in it will cause the PCM to get some wacky info from the MAF sensor causing it to shift with a bump and whine. For the $ 15.00 it will cost you its certainly worth a try.
