Going up hill feels like the car is going to fall apart. When coming to a stop going down hill it also feels the same. It sounds and feels like it's struggling for power and that right their makes me worries. Took my car in a few times after this started occurring in April of 2015 to get serviced and not once the dealership mentioned any transmission problems. Asked if they could check it out for me, they said they did and everything looked fine but it certainly doesn't feel that way. The brakes feel like their going to die and give out on me every time I drive this car. But no one seems to know what the problem really is. I will no longer buy or look at a GM the same anymore!

Just want to say I love Pontiacs. I've owned 2 Bonnevilles before this Grand Prix and never had a problem with them. I purchased this one and I'm having problems with the transmission. I've looked it up and you have been having problems with these transmissions for a long time. Why isn't there a recall on them? What are you waiting on someone to get killed because of this problem before you have a recall?!!! I've always loved GMs but think I'm going to have to start buying Ford's If you don't do something. The problem is here and you need to man up and fix it.

I have been dealing with this situation for almost 6 months, I bought the car in June and it run fine I always wanted a Grand Prix and it was everything that I expected, for a few weeks...It all started going up a hill to work, it wasn't a bad problem at first it was just stuttering a bit going up the hill...well I didn't think much about it and here 6 months later when I stop at red lights the transmission fluid reaches 201 and it usually operates at about 170.

But the problem I am having is now when I start from a stand still it feels like the transmission is falling out of the car when it shifts from 1-2 and from 3-4 and the faster I am going the worse the hit is so to speak..I would like for GM to realize they are costing American people money when they put a V6 tranny in a V8 style body. I would like GM to recall and fix this problem that from what i seen a lot of people are having,

I was out of state for a funeral and went to visit neighboring relative. Driving through the middle of downtown my transmission started slipping. I had to completely shut the car off and restart it to get it to drive again. After several attempts at doing this the transmission started getting stuck in 1st or 2nd gear. This happened out of the blue. I never had a problem or any other type of issues with my car. I am a female so I do not rag on my vehicle even though I know how powerful it is.

It only has a hundred twenty five thousand miles on it so I figured it would be a basic transmission flush or maybe a shift module. I took it into the shop and they told me my only option was to rebuild or replace that. As I've been reading I guess I'm lucky because I made it to 125,000 miles...And it seems that $1700 is a pretty good price to fix.

What really pisses me off as I've had vehicles upwards of 200,000 miles are better and never had transmission issues. I've read it's because they put the v6 transmission in the v8 and it can't handle the torque.

Seems to be that this would be a manufacturer issue. I take care of my car as it is my only mode of transportation. Now I'm having trouble getting to work, making it to doctors appointments, and getting my kids to where they need to go. My car doesn't even hardly have a scratch and it does not have any dents or major flaws.

Seems like Chevy should take some responsibility!!

I purchased my car in 2009 of July. I have had so many problems with this car, it all started with the hubs in 2010 then my car started slipping and when you put my car in park, you can still move the stick into reverse, neutral, drive, 1, 2, or 3. I know that can't be normal. Then in 2013 of November my car had a knocking nose which was the bearings had to be replaced. My car still has problems with shutting off on Highway, and my power steering is shot. My ABS system hasn't worked in a year. I do not recommend this piece of crap car. Worst car to buy.

After paying my last payment on this GM car, without any warning, the auto transmission started to act up. I can drive it if I just got in it and started the motor and put it in drive, but the first time I have to stop at a light or stop sign I would not be able to move forward again until I put the car in park, turn the key off then start the car again and put it in drive to get it to move. The dealership had done a tranny service about 5k ago.

Has anyone else with the same car had this problem? If so what was the fix?

Problem started at about 25000 miles on RARE occasions. Almost feels like you are riding the clutch pulling away from a stop then just dump the clutch and it grabs. ITS AN AUTOMATIC!!! Now at 40000+ miles, it is doing it just about everday. Usually within the first couple miles of the drive after sitting overnight or at end of a work day sitting for @ 8 hours but not everytime. Sometimes it is a minimal slip, others, so severe that the whole car chatters so bad and hear something sounding like teeth trying to grab. Report everytime I take it in to dealer for oil change and can not be repeated (of course)and it does not leave any codes so they can't pursue investigation. I have it overnight at dealer now and trans specialist is taking it home with a monitor hooked up and with fingers crossed, hoping it will happen on his way into work.

I luckily have a warranty up to 94000+ miles so I am covered but this is very annoying and dangerous when not expecting it, pulling out in traffic and you don't have the power to get going, those couple of seconds are critical. Now I just anticipate there will be no power and wait for plenty of clearance to pull out. MANY near misses.

Posting here, I am hoping someone else out there has or had the same problem and at what point were you able to get this fixed. My guys won't touch it without evidence, of course that comes from corporate of the warranty, so let it destroy the rest of the components along the way and cost even more in the end. So typical.

BUT absolutely love the car, best of all worlds with power, comfort, style and gas mileage considering its a big V8.
