    I bought a 2009 GMC Acadia on 7/11/13 w/79,000 miles on it, from a reputable dealership, supposedly. I have had it in the shop 5 times since I bought it. Cruise control went out, Catalytic converter replaced, timing chains replaced, battery replaced, motor mount replaced, and now the transmission needs replacing. I was told it had a 5yr/100,000 mile Powertrain warranty on it, but then on 10/16/13, I was told that expired on 7/29/13, because the car was sold in July 2008. Prior to buying an Acadia, I read where there were many problems with the 2007 & 2008 transmissions and that new transmissions were installed in Acadias in 2010. How can I prove if this is true? And how much should a transmission replacement cost?

    Unfortunately, the 6T70/75 transmission used in the 2007-2009 GMC Acadia, 2007-2009 Buick Enclave, 2007-2009 Saturn Outlook, and 2007-2009 Chevrolet Traverse is prone to early failure, due to a design flaw (specifically, a weak 3-5-Reverse wave plate). GM redesigned some of the internal components, and started installing the revised 6T70/75 transmission during the 2009 model year. A new GM tranny from the dealer usually costs $3,000-$4,000. But the revised transmission should keep you rolling for a good long time (until something else breaks:-)


    I purchased a 2009 GMC Acadia SLT-2 from a large and well known car dealership. It also had approximately 79,000 miles on it but was purchased in April 2014. Since, I have received more recall notifications in the mail then what should be deemed legal. I mean seriously, after 2-3 I feel someone should step in and assist the customer. Anyway, I have also had the catalytic converter replaced just last year, yes less than two years in and of course it was out of warranty. I’ve also replaced the battery and numerous other things. Now, the transmission is going out (like Spyderman). I’m at 94,000 and the transmission needs replacement. This is a bummer as I am reading that this vehicle’s transmission goes out at around 90,000 miles. This is awful as I am paying a car note on a vehicle I been lost trust in to travel far distances in and now I cannot afford to replace the transmission. Help someone this is not right. I’ve never ever owned any other car before this one that I was afraid to drive. Well, now I cannot drive it or else my engine may lock up. Come on GMC.
