On February 2010 (56265 miles) my wifes 2007 Outlook have transmission problems and we took it to our local GM dealer. They replaced the clutch wave plate and 3/5/reverse.
On July 2010 (65289 miles) we took car in and complained that it was not shifting properly and was told that trans. was working properly at this time.
On March 2011 (82357 miles) took car in and complained about trans. and was told that it was operating as normal.
On June 2011 (87264 miles) took car in and complained about trans. and was told that it was operating as normal.
On October 2011 (93535 miles) took car in and complained about trans. and was told that it was operating as normal. they replace water pump under warranty at this visit.
On December 2011 (96911 miles) took car in and paid them $49.95 to diagnose trans. problems. they said they drolve it and trans. is wolrking as designed. they kept my 50 bucks.
On February 2012 (99399 miles) paid another 50 bucks and was told that throttle body would be replaced under warranty. told that this could be causing shifting problems. Check engine light on. replaced throttle body and was told that trans. was operating as normal.
On October 2012 (112121 miles) check engine light on, wont shift, but when you turn car off then on it resets and does not shift too bad. Check engine light goes off after about an hour. Paid another 50 bucks to diagnose and suprise!!!! They now says that i need a new transmission. Dealer wants to rebuild trans. and I just want them to put a remanufactured one in. They say the my responsibility for the rebuild would be 55% but they do not know a cost breakdown or a total. They have worked on this trans. before, why would I trust them to work on it again.
Do not feel comfortable about giving them an open checkbook and if I have to pay some then I want the remanufactured unit that has a warranty. Everyone I have talked to said that the reman. is the best because it has all the updates and bugs worked out of it. They said rebuild would have only 90 day warranty.
We have meeting with service manager tomorrow 11/23/2012 at 9:00am.
I feel that this has been an ongoing warranty issue from the 65000 mile mark and that they have just been stringing us along till the point that this car is out of warranty. I would like a reman. unit and would like to pay little to nothing and they will never see me again.
Also you may have wondered why we have been so patient with this issue. I work for a company that is a vendor for this deallership and I have been trying to keep my cool and not rain fire down on them. We are beyond frustration. We will talk to the service manager tomorrow. If I do not like what he has to say, who do I contact? someone from GM? or do I go straight to the BAR(bureau of auto repair)/DMV and open a case on this. Any advise or help on this issue would be greatly appreciated. VIN is 5GZER13747J118856. Dealership BAR# is AC171332. The case # when they worked on the trans. was 11231012. Thanks

Research the part number of the 3/5/R waveplate installed in 2010. It might not have been the newest revision. If is isn't then that's why it failed again.

This is a pretty common issue. It is hard to tell what GM will do.

Where are you located?
There is a member on the Acadia forum (keydiesel) and has his own shop and works on these all the time.
If youre in his area-- maybe thats where you can go instead.

I believe hes in Michigan.

heres a thread on him- and has pics of a trans he had taken apart.

What part number should I look for? I have a 25701WG294. Does that look like the part number?

No letters. Think newest 3/5/R is 242554103

It is a common, well known problem and should be recalled. Please help us all with the same problem and go to the NHTSA website to fill out the short questionnaire that will force a recall, given enough complaints.

This is what GM answer to me for my transmission went out on my 2008 Saturn Outlook XR AWD. I told GM that my vehicle was not safe on the road and had sudden acceleration problem and this is what GM expert have to answer to me with. "so my email could be read by GM and their employees and make joke and laugh at it". "No we know your vehicle is not safe on the road but we at GM does not care with happen to you or your love one and anyone else on the road".

MODIFIED - Received information pertaining to the response posted previously and that is was not a correct statement. If you wish to post problems with your vehicle that is fine but make sure what you post is correct and not misleading. GM employees (CSR) must share among themselves problems which many believe are problems and the CSR Michelle we have on this board we appreciate her being here.

So we got the car back today and they had to replace the torque converter and the transmission control module. Michelle transferred me to a nice gentleman named Ray to handle my case. He said that the dealership was working with me and that my responsibility was still 55% even though these problems have been around since the 57000 mile mark. They said that it would cost me $1150.00 to fix car. The service person even told me that they were going to replace one of the coolant lines and that these are usually not covered by warranty but that they were able to get it covered. When I looked at my invoice it stated that the tech had damaged the coolant line when they were removing the trans. They used all remanufactured parts and claim that the total repair came to $2200.00 I think I got ripped off. There is no way that this costs this much. Reman. torque converter is $150 and a reman. trans control module is $250. With 10 hours of labor @ $100 an hour that equals about $1400. 55% should be about $850.
Needless to say Michelle and Ray were pretty much worthless. Dealer said that GM was calling all the shots and GM said that the dealer had the decision making authority. All I got was double talk and not much else.
Filing my claim with the Bureau of Automobile Repair and the DMV tomorrow. Good going GM. Way to stand behind your product.

If anyone has any info. that would help please let me know thanks ....

@srio, after you local dealership diagnoses the Outlook, don’t hesitate to talk with the service manager about cost assistance. Please let me know how things are going when you take this in and we’ll go from there.

I hope you have a wonderful New Year’s Eve celebrating and be safe.

Michelle, Chevrolet Customer Service
I’ll be out of the office from 4:30pm EST today through 01/01/13.
