#430 of 479 2002 Impala Shifting Issues
Dec 24, 2012 (10:41 am)
my 02 impala runs fine, but will shift rapidly back and forth between 3rd and 4th gear at middle speeds, especially while on a slight incline. once it gets through this range, it will level out nicely over 60 mph. does anyone have some incites on this problem?

Have you tried replacing the transmission fluid and cleaning the magnet/pan?
This often works wonders on GM transmissions. GM lies about the fluid change interval. Don't let it go for more than 50000 miles. Those sticking components get smooth again when fresh fluid cleans the varnish off.

I own a 2008 Impala that I have had concerns about the transmission and clutch since I bought it. I have not had a clean transmission that includes the button on the gear shift not fully coming out in any gear and being able to switch gear without needed to push the button in.
Recently, I cannot remove the key from the ignition after shutting down while having the car in park. I can leave the key in the ignition and remove everything else from the key and lock the car using the remote, but the key remains in the ignition.
What can I do to remove the key? Also is this covered under warranty since the car has about 85,000 miles? Is GM willing to remain on future car purchase lists for my consideration?

I purchased (financed) an 06 Impala LTZ, and man, I tell ya, I thought I got a bad lemon, but after reading all these issues regarding the transmission, I see it's not just me. Oh, my transmission shifts normal, and smooth. My issue is it tends to stick when you put it from reverse back into drive. There's about a 3-4 second delay, at which most times, I'm already trying to drive, and the car lurches forward with a really harsh kick to the transmission. I'm on the edge with this transmission one day just not going into gear anymore.

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?
#438 of 479 Transmissin slip and performance observation
Apr 05, 2013 (10:45 am)
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.
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.
#439 of 479 2006 impala transmission
Apr 29, 2013 (10:12 am)
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....
