2007 GMC Acadia: stuck in gear or won't shift

Filed Aug 6, 2021 · Transmission · AZ

when accelerating onto the freeway, hit 55mph and the car just stopped going. it would not go into any gear, turned off car and it still wouldnt go into gear. AAA showed up said "oh, we see this in the acadia all the time" plugged something in under the dash, the check engine light went off and he said "there you go, now it'll work fine, just dont give it hard gas when getting up to speed" turns out the code was a tranny code that when he cleared it the tranny would then work. Its bad enough i have to deal with this leaking A/C unit, 3 cans a week, and that smell is terrible, i cant even get the car up to speed when entering the freeway traffic. please make gmc fix these issues, i know im not the only one with both issues. Thank you.

Vehicle. Would not shift out of first gear. Would get to almost 5 RPM before it finally shifted. When it did shift out, it shifted hard. Problemed started in august 2012 after we purchased and her it is july 2015. Dealership said they can't find anything wrong. The gas peddle did get stuck one time when the vehicle. Wouldn't shift out. Now my parking break has a leak and is always saying that the break is on.

Upon entering the highway the 2007 acadia would not shift either into or out of 3rd gear, I'm not sure. I could not tell what was happening and when I determined this was not going to correct itself I exited the highway. I've recieved a letter from gm stating that vehicles equiped with 6t70 and 6t75 6 speed automatic transmissions are experiencing cracked or fractured wave plates. This clearly is a faulty part as it is occurring on many versions of this vehicle and has been upgraded. I was lucky in that it was only me in the auto and not the entire family when this happened. Very dangerous.

I bought a new gmc acadia in 2007. January 8, 2008 gmc did a software upgrade to my transmission. At that point my mileage dropped about 6 miles per gallon and did not shift as nice as original. In late summer of 2014 I notice that my transmission was not right. On september 16, 2014 I had to replace the transmission at a cost of $3,999 at only 123,228 miles. This car was built and advertised to pull boats and campers. I have not pulled anything ever with the car. In march of 2015 I received a letter from gmc that they would reimburse 2007 gmc acadia owners if they have had problems with the transmission. The car must be under 10 years old and under 120,000 miles. My car was under 10 years old, but over on mileage by 3,228 miles. Gmc would not cover any of it. It is pretty poor when a car company can not build a $40,000 car with a transmission that would last.

On highway, transmission was stuck and would not shift. Check engine light turned on. Was attempting to merge onto busy highway and due to high engine revving and not shifting had to keep the vehicle under 45 MPH. Merging was dangerous and had to drive under very busy conditions and leave the highway quickly. Did so luckily and returned home safely. Once home with self-purchased diagnostics tool read error codes p0017, p0716 and p0700, some pertaining to timing chain stretch (known issues on this vehicle) and transmission plate issues (also known). Gm has never contacted me regarding these and I consider this vehicle unsafe with very little warning about what appear to be 2 manufacturer-known (gmc) issues regarding timing chain stretch and faulty transmissions right at about the time power train warranties expire. We are just over the warranty expiration of 100,000 miles on powertrain and are staring at significant expense and a car we just don't trust anymore.

Vehicle would not shift properly and reverse would not work. Had gmc fix the transmission but I had to come out of pocket as it was under mileage for the warranty but past the date by a few months. Today 5/2/14, I'm being told that the transmission is going out again 1 year and 4 months after they fixed it. Gmc says they only warranty for 1 year. Unsafe vehicle for a transmission to be replaced by gmc twice within 1 1/2 years and under 115,000 miles.

2007 gmc acadia with 108,000 miles. Check engine light appeared and the transmission went into safe mode and would not shift out of 2nd gear. Code generated was the "shift solenoid stuck open". Transmission shop stated that the transmission will totally fail soon and needed to be rebuild at a cost of $4500. The transmission guy said that I was lucky to get over 100,000 miles because they usually fail between 80-90,000 miles. He stated it was a horrible design for a transmission and inadequate parts were used inside. Not an uncommon problem for this vehicle. Researching all of the complaints, there should be a recall. Gm's attitude is that the warranty is up and it's your problem, so you must pay for our design flaws.

I have a 2007 gmc acadia. I have had to have multiple work don on the transmission and yesterday it slipped out of gear while driving. I tried to accelerate and the engine revved and the rpms went high but the transmission would not shift. Had I been on the highway at a high speed this could have been the cause of a serious accident. I took it to my dealer and they said the transmission control module had went bad and it cost me $1400.00...at 83,00 miles???? I think gmc should take responsibility for the terrible workmanship of their transmissions in the 2007 acadia.
