My main complaint is about my trans. I have a 2000 Monte Carlo the overdrive does not work so I take it to GM they said I had a code stored on my computer and that the problem was a control or pressure regulator. They made the repair, called me and said well we have good news, the code is now gone but your overdrive still does not work.they were willing to negotiate a possible share the cost or they may cover the whole cost depending upon what they found, yea right I had already spent 500 +, I said no and called GM's customer service.no help there. This problem was detected slightly after my warranty I feel that if a code is listed on the cars computer somehow the driver should be aware of it. I was probably driving with a defective part and not knowing it, causing major damage for who knows how long. The reason I am writing is because I check from time to time hoping to find a recall but every time I check all I find is more complaints on GM's 4T65E in a lot of other cars as well. I also have some of the other problems I see other people complaining about such as front brake and or caliper problems rattling and wearing out prematurely, heater core problems, they put stop leak in my oil and antifreeze without telling me, they did give me a ticket on that, about a week or two later they sent me a letter stating they if I paid to have any leaks repaired I may be untitled to refund and yes I now have an oil leak. If this letter can't help me out maybe it can help someone else out. I feel there are plenty of other people you probably have not heard from.than you.

I have a 2000 Monte Carlo ls coupe that I purchased on 10/2000. I started experiencing front brake vibrations at 11000 miles. The dealer said the front rotor went out-of round and they resurfaced them. This vibration returned at the 22000-mile mark. Back to the dealer I went and this time they had to replace the front rotors. Well the car just reached the 32000-mile mark and the vibration is back. Again I see the dealer for this problem and this time theyre claiming that this is a wearable item and they can not cover it under the vehicle warranty, and that there would a charge. Apparently something is causing this problem to recur every 11  12 thousand miles, and I know itS not my driving habit, I have driven different cars/trucks for 28 years and never had rotors to warp. I called the GM customer service number and all they would say is that they agree with the dealer, though they filed it and gave me the file #1-120464560. Ive heard and read of this same problem from other owners of Monte Carlo and ImpalaS all around the 2000  2003 models. So it looks like GM doesn't want to look at this problem or do anything about it until something bad happens.

Rotors have not been replaced but the shaking is getting worse.

Vehicle suddenly shuddered upon braking, had longer than normal stopping distance. Hit debris in road, causing wheel and alignment damage. All four rotors determined to be prematurely warped, probably due to defective manufacturing. Chevrolet disllowed claim for repairs, citing "no service records for vehicle at dealership from where purchased"!

Rear brakes wobble, causing a bad vibration that can be felt through the seat when driving. At around 11,000 miles I took the car back to the dealer. The rotors were turned on all 4 wheels. This helped, but after about 2000 miles the wobble and vibration returned. I feel there is a problem with the anti-lock brakes causing the vibration, because when I mash on the brakes hard the vibration is much less, sometimes no vibration at all. The car does not want to stop well unless pressing hard on the brake pedal, especially when wet. I am sending you this message because I feel there is a problem with the anti-lock braking system and I am tired of being treated like I am a liar and I am stupid. I have driven several hundreds of thousands of miles and I know how brakes are supposed to work. The brakes on this car do not perform properly. My driving habits allow me to get 70,000 plus miles on a set of brakes. I currently have a 1999 Dodge Ram with over 70,000 miles, that will not need brakes for another 30,000 miles probably. I need your assistance in this matter. Thank you.
