Scan it and check fluid first. These pumps are known to fail!

I have had transmission slipping problems with both of my 2008 Chevy Impalas. They both have less than 70,000 miles on them. The same problem. Slipping when getting started. When it's cold it's happens more.
Are these cars still covered by a warranty?
Does anyone else have this problem?

I own a 2005 Chevy Impala, and it has recently started having transmission problems. Occasionally the transmission would clunk when put into drive, but now the worst problem is the transmission has been slipping for approx. 4 to 5 days, then earlier today, it would not move at all after I was stopped at a red. I had to push the car off to the side of the road, then I had it towed. After the tow truck driver dropped it off at my apartment complex, my daughter, boyfriend and I pushed it into my parking spot, while doing this we had to push it backwards in order to get it parked in my spot straighter, so I put the car into park so it would not roll too far backwards, when I did this my boyfriend notice that it sounded like it shifted. I went through the gears and low and behold it was shifting in Park, Reverse, and Drive, but not 3rd, 2nd, or 1st gears. I put it into Drive and pulled it into my spot with no problems at all. I have not driven it any where yet and do not plan on driving it any where other than the repair shop tomorrow. Does anyone have any suggestions for a single female, with no money to spend on a transmission, or any kind of auto repairs for that matter?
From reading all the forums that I have read so far, it seems to me that GM should be held responsible for all these transmission repairs that Impala owners are having to have done, has anyone filed a class action suite against them for these issues?

I own a 2006 Impala LT with all but 10K of 155K miles being mine. I have been plagued by intermittent performance and transmission slippage issues for quite some time. Before getting soaked for an unnecessary tune-up (factory plugs lasted well over 100K) or transmission repair you may want to try this:1)The air intake comes in from behind the drive’s headlight into the engine via the throttle body at the top-drive’s side of the motor. The air filter is located in the area of the intake in front of the drives’ side wheel well under the body support bar which is bolted on top between the front bumper and fender (one on each side of engine compartment). While having a clean air filter is important, I cannot stress enough the importance of making sure the “air box” is properly sealed once it has been opened to inspect/replace the air filter. With the air filter in place you MUST angle the bottom of the box in first so the two plastic feet are locked in place before tohe top is swiveled into place and secured with the two latches at the top. If the bottom is not locked in place your car will not, can not, run properly.
Why? The sensors are located where the air initially enters the intake behind the driver’s headlight. Any air sucked in after these sensors ( i.e.: air filter location if not sealed properly) is not seen by the sensors, causing the modules to ultimately provide incorrect information related to air temp and volume, resulting in awful performance.
2) There seems to be “drift” issues with sensor and motor control sub-systems in many cars, and the 2006 Impala LT is no exception. What this means to you is your car has been lead to believe, via input from the easily over 50 sensors and feedback circuits, that it is running properly…. and this is wrong. With nothing to reset this this status the car will continue to run like garbage… like mine did.
So…
With the car off (works best after car is been driven or warmed up for a few minutes), keys out, doors closed (so dome light is out) and security not enabled (doors not locked), lift the hood. Along the passenger side behind the battery is the fuse box. Remove the cover inside you will see a fuse locator. About one-third of the way down on the right side and directly below the STRTR relay are two fuses. These are the (yellow) 15A ECM/TCM and (red) 10A TRANS.
Removing the 15A ECM/TCM fuse for a minute and then reinserting resets the engine performance to default, allowing the engine to “retrain” itself from an acceptable (powerful) level.
Removing the 10A TRANS fuse for a minute and then reinserting will reset transmission values and, unbelievably, the slip disappears/ diminishes drastically.
I have done this periodically for well over 50k miles and have never hurt/blown a body, engine, or transmission control module. Replace the fuse box cover, start it up, and take it on a test drive.

Hello people, its me again. I traded for 2006 impala & so sorry I did this. It blew the original tranny I replaced that with a auto wrecker tranny was ok for bout a yr or so. I parked it for 4-5 months the tranny was ok but wen I started using it again the car was really sluggish on take off. I thought might work itself out after being parked for bit but no it didn't. I found out it would only manual shift 1-2-3-4 I would have to do this every time I stopped. Then I lost 1st gear and wen shifting it would make loud clunking noise. So people is this tranny worth rebuilding or should I jus go out find another tranny to rebuild, I read an article of one owner who modified his tranny I'm thinking of doin the same. any advice plz help me....#440 of 441 2006 Impala - Bad Transmission by notchevy

My 2006 Impala is approaching 115K miles and it is starting to fall apart. The most significant issue is the transmission is slipping and the vehicle is no longer safe to drive. I'm in Afghanistan and my wife was almost hit by another vehicle as the transmission slipped in the middle of an intersection. The mechanic wants to charge $4000 to replace the transmission. Along with the transmission other issues are starting to show up. An oil leak was just fixed. The air door actuators are bad and clicking horribly. I've lost faith in Chevy and the car I once enjoyed owning. Now my Impala is an unsafe money pit. Time to find a new car brand...might have to try Toyota or Honda. Anybody have luck with Ford?#441 of 441 Re: 2008 Transmission Problem [dwhitmer1960] by sickofgm2

I'm sorry to tell you, but within a year they will tell you that you need a new transmission for $3000....We had transmission work done on our Impala after the first yr and then again at 4 yrs.....they replaced the selenoid on ours and our transmission is bad again....I am now arguing with GM and the dealership. I contacted a transmission person that has been in business for 35 yrs in our area and he said he has never seen a yr/model of car have as many problems....he also said last yr he replaced more transmissions on Impalas than on any other car......last wk i paid the dealership $150 to diagnose the problem and they didn't come up with anything and are now saying to properly diagnose it they want another $500 minimum.
