I strongly encourage all of you to look into the internal service memos offered by other customers throughout this forum involving the torque converter. There are defects in one of the impala drive trains. Mine happened to be one of them. I have a 2007 SS Impala that I will be selling as soon as it is repaired. The first sign of a problem with your transmission will be a slight vibration while in drive. This will then become a slight groan through normal driving about a month later. Following this, your transmission will begin to slip and lurch violently. I got my car to a chevrolet dealership who told me it was my fault for letting someone other than him do my 50000 mile transmission fluid and filter change. He said, I quote, "a clip was missing". The problem he overlooked was that the transmission had run fine for the next 10000 miles and a year later until the first problems began. As a result, he said the other firm who performed the work damaged the transmission. Fortunately for me the firm that performed the work has taken it upon themselves to tow the car back to their business to investigate every part of the transmission and they have already picked up on the torque converter problem through the computer.
Before you take your car back to a Chevrolet service center, arm yourself with every internal service bulletin involving the torque converter. Unfortunately, these internal memos have never quite made it into an actual recall which is so sad and shows what the company has become. Good Luck. We were all a Chevy family for many, many years, but unfortunately, things change and companies and their priorities change.

Lets face it, the Impala sucks! I personally own a 2001 Impala LS with every option except heated seats. THANK GOD I'M A MECHANIC BECAUSE THIS CAR COULD KILL SOMEONE IF LEFT UNSERVICED! My car is OVER SERVICED and I can barely keep it running.
Here is a run down of what you need to do to fix the most common problems with the least amount of money.
1. ABS-TRACTION CONTROL(piece of crap and dangerous)
-replace wiring from front wheel sensors all the way back as close as you can get to the main branch of the harness. You must solder these wires to ensure it will last and add two layers of shrink tube if you can and then double tape the wiring from the frame out to the tire. NO MORE WASTING MONEY ON NEW HUBS FOR 100 A PIECE!!!!!!! By the way chevy hosed you on the wheel bearing and sensor deal because they are the only brand that has the wheel speed sensor in the wheel hub and are not separate pieces.
2. TRANSMISSION SLIPPING?
-ok guys this is a combination deal and not one problem is the main issue. first, change cat and res tube on exhaust. second, get a reverse flush on the tranny and ADD A BOTTLE OF SEA-FOAM FOR TRANNYS(this will save you 1,000's). If you took my advice and changed the cat then you might want to find out what caused it to go bad. well I'll tell you what made it go bad. GM USED CRAP SEALS ON THE INTAKE AND AT 60,000 THEY START TO LEAK AND BREAK DOWN SENDING COOLANT AND OIL INTO THE CYLINDERS AND ONTO THE CAT. The added back pressure from the cat will cause the tranny to work hard and then you get a bad pressure solenoid as a result.
3. INTAKE MANIFOLD SEALS
-YOU MUST BUY THE FEL-PRO 2 METAL SEALS!!!!! TO FIX.
Follow my directions and not the book on install of these! First, you must try to resurface the area around the coolant jackets because of corrosion. Next, a small layer of RTV around the ports and then put the seals on. Next, clean all bolts and put thread sealant on and hand tighten a little at a time following a pattern from the inside out in at least three to four sequences. DO NOT USE A TORQUE WRENCH-TO MANY ISSUES THAT GIVE YOU FALSE READINGS AT SUCH A LOW FT-LB OF 15 LBS. YOU WILL KNOW WHEN YOU HIT THE RIGHT TIGHTNESS BUT NEVER GO PAST TIGHT TO MAKE IT OVERTIGHT. THE SEALS WILL SMASH TO MUCH AND CONTORT.
4. HEATER/AC ISSUES
-First off you have a bad resistor if 1-4 settings don't work and 5 does. why? because only 5 doesn't use the resistor because it is full power! If five doesn't work start off by checking the fuse on the passenger side. If the fuse is bad thank your lucky stars. If not then your heater control unit is bad or your fan. You will know what to do if you have the skills for the next steps, if not take it too a dealer.
5. WATER ON THE PASSENGER FLOOR
-SUPER EASY FIX- open hood and then take off the plastic cover where your cabin filter is on the pass. side just below windshield. You will see a rubber seal that has fallen off. Use silicone or rtv to stick back in place. You're done!
6. POPPING NOISE IN SUSPENSION
-ok now this all depends on what else you've already replaced. If you're at your wits end and have replace almost everything you will understand. Chevy cheaped out and only put one spot on each side of the sub frame to connect it to the unibody. Over time oil soaks the one of the passenger side and it starts to pop when putting the car into gear or hitting bumps and slow speeds.
Also, the strut tower mounts are made to last a month from the factory lol. They are plastic on plastic and dirt gets in between the plates and they bind up and make the steering feel awful.
7. TURN SIGNAL INTERMITTENT
-well this is just plain stupid because the turn signals go thru the hazard switch and if you jiggle the hazard switch when having a turn signal issue and you'll notice they will either go back on or give you a flicker of hope. problem solved and ebay has the hazard switch for 25 if you need it cheap.
I HAVE REPLACED AND REPAIRED THESE ISSUES SO MANY TIMES ON MY CAR i CAN'T TAKE IT BUT WITH THE ECONOMY I CAN'T AFFORD A NEW CAR. I JUST REPLACED THE ENGINE AND TRANNY IN MY IMPALA WITH A 2004 BUICK REGAL ENGINE AND TRANNY. GUESS WHAT? IT HAS A BAD PRESSURE SOLENOID IN THE TRANNY.....I WANT TO TAKE A ROCKET LAUNCHER TO MY CHEVY PIECE OF CRAP. OUR FAMILY HAS NICKNAMED THE IMPALA THE LIMPALA BECAUSE ALL IT DOES IS LIMP ALONG. I HATE YOU CHEVY AND YOUR DAMN BAIL-OUT AND YOUR UNIONS THAT RIP OFF AMERICANS.
I WILL BE BUYING A HONDA OR TOYOTA WHEN I HAVE THE MONEY AND I KNOW THEY WILL TREAT ME RIGHT.
OH AND WHAT'D YOU DO TO YOUR DEALERS? DID YOU TELL THEM TO DO EVERYTHING POSSIBLE TO NOT REPLACE THE CATALYTIC ON THE RECALL. MY CAR HAD 115,000 AND THE CAT WAS SO OBVIOUSLY BAD BUT BOTH CHEVY DEALERS IN TOWN WOULDN'T REPLACE IT. YOU SUCK CHEVY AND I HOPE EVERYONE STANDS UP AGAINST YOU AND YOUR DAMN UNIONS.

On November 4, 2012 I have dropped my 2008 SS Impala off at Jim McKay Chevrolet in Fairfax, VA. This will be the second time for the transmission. VIN #2G1WD58C989162178. Hard shifting shutter from a stop 1st to 2nd. Jim McKay said no codes and it didn't do it for them. It's doesn't do it all the time.

That is exactly what my local dealer in FL told me, plus no codes on the onstar either....

Also told Jim McKay to keep it for 4 or 5 days to test drive it. I also told the service guy that I will come and drive it and have one of the techs ride with me.

well #392of 409 If and only If none of us purchased another GM car we can make them feel it, like we have to feel it. just keep telling folks and at some point gm will have to face the loyal customers they screwed! I'm so pro 'non" gm. funny how the dealers know this and will try to get you to buy this crappy car (I know) another of my family members went to gm up in nj rt 22. needless to say when I was done they went across the road and picked up a honda. sorry gm I can't sit back and watch you do this to people.

Take it from someone who knows....I have just had my 2007 SS Impala Transmission rebuilt and not by GM since they said the company that last did the routine transmission servicing caused they problem. (the transmission company management were as shocked to find this out as I was but held on to their integrity with me by fixing it at just the cost of the parts to completely break down the transmission.
I am afraid from the description you provide that you have about 3,000 miles left before the transmission begins to lurch from standing still. Start recording this problem now with GM. If it is not covered under the ORIGINAL 3 year warranty, more than likely, they will not cover it or find a reason not to. They will offer you an option of purchasing a new transmission at about 3,000. Do not accept this offer. The transmission must be broken down. There is a flaw in its design. That is the reason the new transmission is cheaper than rebuilding it. Sorry for your problems. I know how you feel, but I don't think the flush will work.
