Chevy Venture Transmission Issues
i have a question on my chevy venture 2003 front wheel drive my transmission broke so i can get a transmission for $200 but its fromm a 2003 chevy impala both cars have the same engine and by the looks of it the transmissions look the same. I checked the transmission filters if the venture and the impala have the same ones and they do so does anybody know if the venture and the impala transmissions are the same?

98% of the time it is quiet and shifts perfect and smooth in all gears. It seems to be tied to longer drives with altitude changes & warmer Temperatures, but not always? It always goes away before I can get it test driven by a mechanic. Van has 103,000 mi on it now been duing this for the last 40,000 mi at least.
Good luck.
That being said, I had 1/2 a bottle of Lucas Transmission Fix in my garage as I used it when I changed the trans fluid on my Saturn about a month earlier. (It says on the label that its good as preventative maintenance and I put it in my Saturn even though I had no issues with it.) Thinking I had nothing to lose, I put it in the Venture. For about 1 week the problem got much worse. Then it went away...that was 5 months ago...hasn't done it since. Don't know why...don't know if it had anything to do with it...but it went away. You may want to give it a shot........
He has worked as a mechanic in the past, so he and a friend took the tranny out last night (poor guy got back at 2am....it was close to a 5 hour pull) - apparently there is basically a blow hole in my transmission case. He says it looks like there was a "bubble" or what have you in the metal to the case, and it finally gave through (we're close to 100,000 miles).
I'm just curious if anyone else has had an issue with corrosion, etc., and if this is something I should pursue with my mechanic who rebuilt the tranny for me about 2 1/2 years ago.
When my van was shifting, it would do a 'thunk' sound as it geared up, but that was only once in a while. Now that 'thunk' seems to have ended and the shifting is pretty smooth.
I'm wondering if perhaps there is another red fluid used aside from tranny fluid as I cannot seem to find where the leak is coming from exactly.
Thanks,

Doesn't say much about the shop I took it to as I had a coolant flush there a few weeks ago. Guess they lost my business.
Anyone with an answer to this problem? Thanks in advance Corey
Is your check engine light on? Do you have access to a code scanner, if so you may be throwing a code that doesn't make the light come on (many trans codes are like that)
But I'm not sure its a trans problem, sounds like an ignition or fuel problem to me. Maybe a coil pack getting ready to poop out? Or possibly an injector dying? The PCM is probably storing information when this is happening which only a scanner could read. With a scanner, you could even check all of the engine/trans parameters in real time while you are driving, that would probably be the best way to get an answer unless you happen to find someone who had the exact same problem...
Good luck
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
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
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
Why add only a HALF bottle of it?
Are there any risks to using this product?
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...
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.
1. Get a can of mass air flow sensor cleaner and follow the directions to clean the MAF.
2. Change your air filter.
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.
My whine noise is constant as I roll, even if I put the car in neutral and coast with the engine on - of course.
What is mass air flow sensor cleaner and where would I spray it?
I am not a motor head but I can follow simple instructions.
Thanks.
The cleaner comes in a aerosol can and is made by CRC (maybe others too?) You can find it at any decent auto parts store. Just be sure to follow the directions on the can to a "T". And don't let the little red hose on the can contact any part of the MAF sensor.
Good Luck,

The problem was a BAD FRONT WHEEL BEARING.
My local BP garage mechanic put the computer on it, found no transmission codes or anything else wrong with the engine.
He said I had a bad wheel bearing. He replaced it and now the 2000 Venture drives like new with 70,000 miles on it!
Cost was $400.
My clue that they were on the right track was when I was driving to put the car in Neutral and let it coast and it still dragged. To me that meant it must not be a trans problem.
Someone told me its a linkage problem but I have no idea what that means.
I know I need a new one but I don't know whats its properly called.
Cap? socket? I only want to replace what is really necessary.
Chevy Venture 2000.
While driving it sounds as if there is a strain on the engine it shifts into gears but continue with that dragging sound as if it has not shift into another gear.
Sometimes it wants to shut off and it accelerate high when I am driving slow or if I am idling. Even if I put the van into neutral it still does the same.
Please help!
