#60 of 444 2003 Impala Transmission Slipping?
Oct 31, 2007 (6:09 pm)
I have a 2003 Chevy Impala with 115,000 miles on it. The car has been lurching into gear when step on the gas if I am not gentle enough. The problem seems to lessen when the car has been running for a while, but never completely goes away. We took it to our mechanic today and he did a diagnostic check on it. Nothing else was wrong with it and he said that the transmission was slipping. He does not work on trasmissions, and said that it would be a very pricey repair. Does this in fact sound like a trasmission problem or could it be something else? If it is a trasmission problem, is a car with this many miles on it worth the repair or is it time to trade it in? How much are we talking about? Any help would be grealy appreciated!!! Thanks!

My 2003 Impala (100K Miles) has begun to have transmission issues; it is having trouble shifting gears. While driving, it will still eventually get to the right gear, it just hesitates when shifting up or down. And if I am doing in town driving, it doesn't seem to shift down to first. Another odd issue I have is that while driving without cruise control on, at times when I take my foot off of the accelerator, the car seems to maintain the same RPM and at times seems to accelerate. As an example, I turned the cruise control function off, accelerated to 70 mph, then took my foot off of the accelerator and coasted. It took nearly 40 seconds to drop from 70 to 60 mph on flat interstate highway. I decided to turn the car off and restart it and it seemed to correct the problem for about 45 miles and then started shifting irregularly again as it was doing prior to turning the car off. I have read many of the posts here and I think I have a decent understanding of what issues I am facing, I just wanted to present the other symptoms I was having being that they had not been addressed within this forum. Thanks for anyone taking time to read and respond!
#62 of 444 Our 05 Impala story please read....

Hello everyone...This is our story. We bought our 05 impala the 3.4 model in October of 2005. The car had almost 30,000 miles on it. At the time of purchase the car seemed ok they started acting goofy. The tranny seemed like it got confused on a slight upgrade. It would have a long hard shift or pause when pulling from a stop. But no codes ran that we could see. We also started to have a shimmy or vibration problem. Took it in and found that the tires were chewed up metal showing on the inner side. Replaced all four. During tire check the guy took the car out drove it felt the lunge and ran the codes.....Ah ha CODES RUN INTERNALLY FOR TRANSMISSION! Took it into dealership dealer said insufficient data cleared codes. OCT 06 Then this spring found out the spark plugs was not replaced but had been at some point due to was not platinum plugs. Tune up done (Feb 07) With tune up found that the brake job dealership said they did was not the case. Front rotor needed replaced. Full brakes and rotors on front and rear.
All in the mean while the Tranny kept slipping every once in a while. UP TO DATE NOW.. Two weeks ago took car in Tranny codes running p1811, p 1819. Dealer said valve solenoid and valve body bad. Had them replace it. Found cat was bad in test drive replaced that also. Still did not check out vibration in wheels. Went and replaced passanger rim due to it was bent. Helped...took off driver wheel donut on vibration stopped. Replaced rim vibration still there. Was told the cv joints are bad both sides. Others say its the alignment. Who knows tired of getting jerked around. Wish one person would say this is whats wrong this is what you need to do.
Is anyone else having the same problem? If so what can be done?

My 2003 is in at the dealer right now getting a NEW transmission....I've had it 4 1/2 years and it only has 63,000 miles on it. Something about the pressure something in it.....ticks me off! Shouldn't a transmission last longer than 63,000? And get this.......Chevrolet is going to pay half of the cost.....so that tells me there is SOME kind of problem with their transmissions......my half will be $1,550.00 which I really don't have....would love to be in on a class action suit. We also have an Avalanche, which has also had some issues. Definitely will NEVER buy another Chevrolet. Why can't American cars last as long as the foreign???????

How did you get Chevrolet to pay half cost of your new transmission?
We recently had to get a new transmission on our 2001 Impala with 64,000 miles for all the same reasons as these other Impalas with problems postings. We were not offered any compensation from our chevy dealership/service.

I asked my service rep if there was anything he could do considering the age of the car and the mileage. He called me back and said the best he could do was have the transmission taken apart and diagnosed and Chevrolet would pay half. I don't really know the reason, although I think maybe the age of the car might have had something to do with it since it's only 4 1/2 years old. Maybe the age of your car prevented them from offering compensation?

Thank you for your prompt reply. Yes, I suppose age could be a reason. I wasn't smart like you and asked them. Even so, this bad experience, along with other things, and reading other's problems has turned us off, unfortunately. We won't be getting another Impala after this.

I have a 2004 Impala 3.4 liter. the transmission shifts a little hard when I take off from a stop. This does not happen all the time but I was wondering if it could be the Pressure Solenoid.

I just went in to the shop w mine. sounds the same but mine has to get warmed up "driven for while". I was told by dealer that my High pressure solenoid was sticking. and to corect the thing I would need the solenoid replaced + the valve body. 9 hrs labor $1550.00
