The power window switch for the driver side is wired in series with the switch for the passenger side. One of the two switches may be shorted. If not, suspect the power window motor.

Well guys, transmission problems hea? You are not alone. I have a 2000 Montana which started acting up just over 1 year ago and currently have 150k. It's the same observation as most montana's with trany trouble: error code slippage, hard shifting, turn off engine to reset codes and runs ok until it slips again a few times and then back to hard shifting, wineing noise when in hard shifting mode. Did research and most often it is one of the selunoids (sp?) inside the transmission (there are pictures of a worn one on the internet). Anyway, quote is around $2750 to have the transmission replaced - if to speak to low-cost or any transmissionn shop that works with montana's they will have a refurbished transmission ready to install in their rack - most shops suggest that it is not worth the time/effort to take apart and diagose and risk missing components that need changing out that brings up the bill anyway. For city driving i'm planning on just letting it die then replace it but taking it easy on the peddle when shifting as it is hard on the engine if your flooring it when it is doing this. Unless anyone has any success stories where a shop has taken appart, replaced all parts (do a proper job) and put back to gether for the same price as a new one or a re-built one then i'll probably just stick it out a little longer unless someone can convince me otherwise...

I had the same issue with my '05, hard shifting after 10 minutes of driving. I researched it on automotiveforums.com, and there was a member there that installed a $30 shift kit from zzperformance.com on his van, and it stopped the hard shifts. I did the same, flushed with Dexron VI fluid, and all is well.

For some good info on why the 4T65E transmission known problems, surf:
http://www.tripleedgeperformance.com/4T65E_Transmission_Info.html
On a different forum, a person installed a "shift kit" and his van's transmission shift slippage was eliminated. Using Google, search for "4T65E shift kit" and lots of info appears. Well worth searching this area as well...
Also... My local transmission specialists recommends transmission ATF aux cooler (rated for 5,000+ lbs trailer) be installed on all GM 4T65E transmissions. Even if van is only used for "soccer parent" (and non-Towing) driving conditions. From his experience, the 4T65E does NOT like heat. Especially from city stop/go city driving on a hot day conditions. He told me the LPD (Low Pressure Drop) aux transmssion design (like Tru-Cool and Hayden brands) are the best.
If wondering, I installed the Hayden LPD aux cooler on my '09 Montana van. Cost me under $150 (CDN dollars) in needed materials. And, I installed it myself - to keep the cost even lower. re: http://www.makcotransmissionparts.com/OC-1678.html
Hope this helps....

2004 to 2000 swap

My tranny went out in my 2000 van. I bought a used tranny out of a 2004 and installed it. The man said it would bolt right up, It did. But it will not shift into overdrive. Does this transmission take a different computer? I noticed the plug to the tranny has more pins than the original. Any thoughts?
Thanks
Dwayne

I purchased a 2009 montana in march of this year..and I took it back to the dealer when it was two weeks old..when you take your foot off the break before your excelerate it shakes or ( idles rough) the dealership tells me it is the transmission and it is a operational charactersitc of this van. Does anyone else have this problem or know of anyone with this? It is high stall torque converter..and they started using this part in the late 2007 models. They tell me it is in all these vans but I'm not convinced. Please let me know!! Thanks

Like you, my wife (and I) bought a 2009 Montana EWB van as well. Bought in on March 30 2009. Since day 1, our van's movements has been smooth. Smooth ask silk when slowly taking off from idle and smooth as silk when slowing down, then speeding up again (after driving through the school zone). Other then battery replacement, 3rd brake light replacement (which was both under warranty), I've been very pleased with our 2009 Montana van. Especially pleased with its smooth idling and smooth take off behavior. re: No vibrations at all. Actually, I prefer the smoother feeling of this 2009 van when compared to my wife's 2003 Buik FWD "run about" 3.4L vehicle. So far, I'm glad we bought our 2009 Montana 3.9L van.
Hope this helps...
