I definitely feel your pain my friend and I definitely agree that GM should stand by their product. I am afraid that we are STUCK with it. My wife's 2006 Grand Prix GXP had to have the transmission replaced at around 80,000 some odd miles. We went the Jasper route also. I saw on another forum that someone had the same problem and GM reimbursed them about 1/2 the cost. I followed the steps that he mentioned to me and was told by Pontiac customer care that if we had used a certified GM service center we MIGHT have gotten something from GM but since we used a local shop & Jasper tranny we were just out of luck.
My wife loves her car and I am like you I don't want to keep sinking money into an endless pit. Please keep me informed if you find out ANYTHING helpful.
#450 of 498 Acura must stop dumping cars with transmission problem.

Acura is suppose to be a luxury car . It makes no sense that they are making cars with terrible transmission problems. Most of these problems may be because the tranny filters are not servicable as they are built tight into the transmission.
We may need to take up this matter to President Obama and deal the situation just like what Obama did it with Toyota's unintented acceleration. This was going on since 1999 and they keep dumping cars with trasmission issues.

When on the interstate,with speed of 70 mph or over,the car starts kicking in and out of over drive sporadically causing the tack to jump between 1 and 3. Please if anybody knows what is wrong please help.

I had a similar experience on my GXP and GM changed the transmission. Mine started off like that and progressed to all speeds, I'm not convinced its not a computer problem and the slipping in and out of overdrive is not a symptom of the bad cptr that progresses to kill the transmission. My new trans is a little over a yr old and it's starting it again. If u have a ck eng light look for code po328. Good luck the trans cost me over $3300!

It has not done it in any other speeds, just when i am traveling on the highway and at speeds 70 mph or more, also have noticed that it sometimes does it when i am traveling up hill on the highway. The tac meter jumps up and down. I don't have a check engine light,never had one on or come on since it started doing this..... Just wanting to know if anybody knows what is wrong with it and if anybody knows how to fix it?????

That's exactly the way mine started too. Subtle at first...then worse at slower and slower speeds. Eventually your Torque Converter will explode internally....destroying your entire transmission.
You are #334 that I know of so far.....and GM will screw you.

We have a 2006 Grand Prix GXP. Tranny went out. My best advice to you is have a GM service shop do the work. Contact Pontiac customer service and see if they can reimburse you for some of the repair costs. My wife had a local service shop do the work. We contacted Pontiac customer service because another person on this website said they got half their cost back. We were left with the whole thing just because GM didn't do the repair. GM DOES NOT STAND BEHIND THEIR PRODUCTS! The transmissions have been a big problem on several of GM's products but they will not do a damn thing about it. I work for Toyota and they aren't without their problems. Everyone knows about their recalls but they will take responsibility and stand behind their product. GM should have shut down and not gotten help from the bailout. I have driven and owned GM products since I was old enough to drive. That's all my parents owned also. But I don't believe I will own another one after all of the grief I have experienced and by the messages I continue to get from people suffering the same trouble we did.
Good luck to you and I hope they will help you with your problem.
