at about 50,000 miles my transmission started making a banging noise when it shifts. It went smoothly into gear didn't hesitate, become sluggish or jerk as if it slipped, it just banged as if something hit the under side of the vehicle. It kind of went away, now at 100,000 miles it is doing it again and is jerking into gear, anyone have any similar issues?

I am having the same problem with 45000 KM on my 2006 Uplander. It is sluggish at 60 KMH and at 80 KMH when it shifts gears and it feels like I am pulling a trailer. Last week the Van stuck in passing gear on the highway and scared us until I hit the brakes and it released with a bang. Hope this is not a sign of things to come.

I found a website that said the valve body components inside the transmission were failing. it also said that a transmission cooler would extend the life of the transmission? im gonna try it, mine seems to be on its last leg...

Was you analysis correct? Did this fix your problem. I am having the same banging sound as I shift gears.
Any help is appreciated.

Can you give us the web address?
I had my transmission die at only 59000 miles, and 300 miles from home on my 2006. no towing and oil changed every 3000 miles. I am so upset about this and want as much info as possible. If anyone has advise or info, please advise me. My oil changes were at a certified licensed shop but not the dealership, so I am wondering if they will give me a problem with powertrain warranty.
Thanks in advance.

Youknow what I didn't bookmark the page and now I can't find it. I did find another that seems to have inexpensive used engine and transmissions. I had another incident a while back with another car where I purchased a remanufactured transmission for about $2,000, and it only lasted about 2yrs. So now I am very leary about spending a bunch of money on a used, rebuilt, remanufactured of even a new transmission when they all seem to carry the same 12 month warranty.

Oh and a transmission did lighten up the shift stiffness after installing a transmission cooler. For me it's just a litte too little and a little too late. My transmission has been giving me trouble since 50k and I plan on replacing the transmission regardless.

I didn't book mark the page, but I found another that has low price engines and transmissions.

The transmission cooler (kragen auto parts under $100) did reduce the shift stiffness. I think in my case it is just a little too little and a little too late. I plan on replacing the transmission soon.

I am very hesitant on which to buy becuase regardless of how much I spend they all have the same 12 month warranty. I had a bad experience in the past where I spent more to get the fully remanufactured transmission (upward of $2000) and it lasted short of two years.

I did read an article that suggested, one with a shift kit or performance parts would enhance the drive and longevity. It stated that minivan bodies are a bit too heavy for the transmissions that get put into them and so the shift ability commonly comes to it's end between 75k and 120k miles.

Good luck...

have 06 uplander. transmision jerking in/out of gear when at stop light and on acceleration . changed trans. oil and filter,but didn't help. found problem was bad spark plug wires shorting to engine bock on occasion.it was draining enouph power to affect transmision solenoids .moral of story is .....make sure your vehicle is tuned up before you decide to have any major drivetrain work done.

The uplander is a piece of crap. It is a wonder that gm went down the tubes. Its a bad car all the way around I have an 06 and it has given me nothing but trouble. I will never buy another CHEVY ever!!!!!!

Yes the Uplander exactly same type of transimission problem. Yep it is a piece of JUNK!!!
and GM has a thing call "Good Will" and they won't tell you how much of a so call "good will" they are going to give you until the work is done and you are stuck with a bill of $3000. and the most
their good will dollar they put in is $200. to $300. What a JOKE!! We will never buy another piece of domestic junk. My brother was right all along but thought he was bias because he likes Japanese makes. Well our lease is not even up and the transmission is trash and we are $3000. in the HOLE. So from now though the Japanese makes maybe expensive but it is worth it!

I have an 07 Uplander with 50k mis. that occasionally when stopped and then you take off it jumps into gear. Some of these are really hard jolts and sometimes you can hardly notice them. The trans has not been abused. Anyone got any ideas.

I've been fighting the same issue for over 30,000 miles now. My '06 has 70k on it. The dealer found internal damage after I took it in at about 46k. They replaced parts and I still have the issue. I called Chevrolet customer service the other day to see what they can do to resolve the problem and I expect a response on 1/26. The original dealer went out of business and the new dealer won't do a thing because no codes show up. This is a safety issue since the transmission is unreliable when attempting to accerate into traffic.

I made an entry on jan 17th. i took my uplander into the shop because of the hesitating and then jumping into gear problem. They ran it in the shop with the computer hooked up to it and nothing showed up but when they drove it it showed a bad spark plug wire. I believe its the same problem someone else wrote in about. The spark was going to ground and robbing the transmission of the voltage it needs to operate correctly. thank GOD for the person that wrote in about their similar problem. I guarantee the transmission shop would have gladly taken my 2k to fix nothing.

Thanks Bill! You're right, Herbert from Canada wrote he had the same spark plug wire grounding. Chevy did call me back this afternoon with no resolution and they're sending the case to the district manager. Regardless, I'm going to replace the spark plug wires to see if that does any good. I'll be back to let everyone know if it works.

My Uplander has been having harsh upshifts after the vehicle is warm/hot...until, yesterday when I had the battery replaced. Now it seems like the 2-3 shift is too smooth/slippery. Does this make any sense?

My slipping happens regardless of temperature. Unfortunetly, none of the dealers are willing to spend the time to analyze and explore without codes being generated by the component. The dealers say they won't get paid without a code. The district rep asigned my case did call today and will be trying to get more info from the new dealer. Good luck and check back.

John, I'm very interested in hearing if the spark plug wire replacement works for you. Thanks and good luck!

Well, I finally was able to get the spark plugs, wires and battery changed. I noticed 3 very small slips from a complete stop yesterday. The outside temperature was about 68 degrees. As for the major slip and jolt, the jury is still out until I drive it more this week. If I don't have any of the major slips and bangs/jolts during the next 2 weeks, I would say that changing of the above mentioned items had a positive effect on minimizing my problem.
The dealers have failed to look beyond the transmission and take into account the entire system that the transmission requires to operate. Just because it doesn't produce a code doesn't mean there is no problem.
I for one will never purchase a Chevrolet or GM vehicle in the future.
I'll write next week.

Thank you John. I'm curious to see if this works for you. If it does, that's three for three, and I'm absolutely going to try it.

If you don't mind, can you mention what you paid for spark plug wires?

Thanks,
Bill
