car   Automatic Transmission problem 1
Failure Date: 11/19/2010

About 10 miles outside of dallas my check engine light came on but no initial problems. Later that night while driving on the interstate the car would not go faster than 30mph. I returned home that night and left it parked. The next day took it to autozone and the guy did an engine check stating that my transmission has gone out and that it was low on fluids. I added 3 quarts of transmission fluid which seemed to help a little bit, but I do not feel comfortable enough making an 8 hr trip back home.

car   Automatic Transmission problem 3
Failure Date: 02/01/2010

Last summer, my vehicle started stumbling at speeds greater than 50mph on the highway. I had my vehicle serviced several times, without the issue being resolved. I have had the throttle body replaced, tune-up, map sensor, air intake sensor, fuel system cleaned, fan clutch replaced, still had the stumbling problem. Approximately 2 weeks ago I was driving home on the highway, when I heard the engine rev up very high, but I wasn't going any faster. I then pressed on the gas, the engine raced, but I was just coasting. I was able to coast off the highway to the median, thank god nobody was behind me. I also thank god I didn't have my family with me. The mechanic said, that one of the gears inside, the tranny was broken, and the pump had shattered. I would hate to see this happen to someone, and they can not get out of the way, someone could get killed.

car   Automatic Transmission problem 5
Failure Date: 12/12/2009

I have a 2004 Chevrolet Trailblazer SUV 4wd with 61000 miles on it and have lost reverse on it. My mechanic took it apart and found some pieces had broke and it will have to be rebuilt or replaced. After reading about other complaints with people having the same problem I would have to say it is the sun gear. I'm very unhappy to hear that gm doesn't admit to having a problem with this transmission,but it is obvious to me that there is a problem that needs to be addressed.

car   Automatic Transmission problem 6
Failure Date: 07/03/2009

I was driving in traffic and my truck would not accelerate or change gears at all. This was during July 4th of this yr. I had just had it serviced. I had there transmission serviced and was ok until Aug 29th. It happened while I was on the interstate.

car   Automatic Transmission problem 7
Failure Date: 05/09/2009

I have transmission problems with my 2004 trail blazer I first noticed it when I was driving down the road at 55 and all the sudden it was like the vehicle was put in neutral and I pulled to the side shut the vehicle off and tried to start again and it took off fine like nothing was wrong. Then a day or 2 later the same thing happened so I had it towed to the garage. They told me my transmission was bad I was shocked with only 58,000 on the vehicle they showed me the dipstick was rusted right off and asked me what happened I then asked them what happened. So long story short they wanted to charge $3000 to replace because the warranty ran out at 36,000 I refuse to pay when there should be a recall for a problem they admit they have. And to think the government or should I say we the people just bailed this company out as far as I'm concerned if they are going to make junk let go bankrupt.

car   Automatic Transmission problem 9
Failure Date: 11/04/2008

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the transmission sun gear was faulty. An electrical component was burning inside the vehicle, along with abs failure. The vehicle was taken back to the dealer and they stated that there was no guarantee that the vehicle was working properly. The oil needed to be changed, so the contact changed it himself. The failures occurred right after the vehicle was purchased from the dealer. The dealer performed a 120 point inspection, but they never repaired the vehicle. The failure mileage was 101,576.


 
car   Automatic Transmission problem 10
Failure Date: 06/02/2008

Both issues occur daily: apparent transmission problems. . . Vehicle cannot seem to "get in gear" when cruising anywhere from 40 - 70 mph. It bounces back and forth between gears - not normal driving conditions. Multiple trips to 2 different gm dealers has exposed no problems, as they "cannot replicate the problem". They must not have driven the car at those speeds as it does it religiously. Like many other complaints listed here, and throughout searches done for 2004 Trailblazer issues, my tachometer & speedometer are faulty. They do not work properly. . . At any time may show 8000 rpms or 100+ mph when sitting at a stoplight, or resting at 0 rpms and 0 mph when cruising on a highway. This is dangerous, and gm needs to fix this problem ASAP for models experiencing this issue. I'm very disappointed there has not been a recall - my family has always been owners of gm vehicles. . . But will be no more.

Failure Date: 05/14/2008

We took our car on Wednesday 5/14 to superior Chevrolet in cincinnati OH because on Tuesday evening the transmission felt like it was starting to slip and not driving correctly. The dealership contacted us on Thursday 5/15 to say they were waiting for the warranty representative to come out and give approval before it could be repaired. On Friday afternoon, we were advised the claim was denied because there was water in the transmission. The service manager said it was due to a gm defect with the dip stick - the way it was positioned allowed water to get into the transmission and rust, so the warranty was null and void. The service manager said he spoke w/his gm rep and they would agree to "do us a favor" and split the cost of the new transmission - $1200 still out of pocket for us. When we pushed back and asked why we would have to pay anything, they refused to answer - just told us to fight it with our warranty company. I've been researching online to figure out how to fight this and prevent other people from suffering as well. If it's a gm defect in the way the dip stick is positioned, the consumer should not have to pay for the damage caused by the defect. Any help you can provide would be greatly appreciated. The car is a 2004 chevy Trailblazer with a full extended warranty, but it does specifically state it's void if the problem is due to water. After reading on several chat rooms, there seems to be many people with this same issue.

car   Automatic Transmission problem 12
Failure Date: 01/10/2007

We bought our 04 Trailblazer used about a year and a half ago. It was owned by enterprise before and therefore already had 30000 miles on it but we knew that it was maintained well. It is now at 71000 miles and we have done all recommended maintenance. Yesterday, while on the interstate the transmission lost third gear and above. This was dangerous but luckily I got off of the interstate with no incidence. This morning we took the truck to our local and trusted mechanic who determined that the transmission was shot. He called jasper to get a price on a new transmission and during that conversation, jasper informed him that they have done 15 upgrades to this particular gm transmission and that even gm is buying replacement transmissions from them. I think that gm should consider some type of recall on the transmissions due to the obvious amount of problems they are causing. Needless to say. . My warranty is expired and I have to shell out $3000 to repair a 3 yr old vehicle.

car   Automatic Transmission problem 13
Failure Date: 12/29/2006

We bought a 2004 chevy Trailblazer brand new. We had all scheduled maintenance performed. Then in December 29th of 2006 in the evening we experienced a loss of the transmission in third gear. We were trying to merge onto a highway and were almost rear ended by a semi-tractor trailer truck. I quickly pulled off to the break down lane to avert an accident. It has been roughly been six weeks since we dropped the vehicle off at a authorized chevy dealer. Our extended warranty wants to rebuild the transmission. The chevy service department wants to replace it. They are at a stalemate. This vehicle had only 68000 miles on it.

car   Automatic Transmission problem 14
Failure Date: 12/08/2006

While I'm driving the car will just turn off. I can be at a light, turning, merging onto traffic or just sitting in traffic. I've been able to avoid three accident to date. I did bring the car in to the dealer - they fixed it. Until it happened three days later. It happens 6 out of the 7 days a week.

Transmission went out.

car   Automatic Transmission problem 16
Failure Date: 07/28/2005

2004 Chevrolet Trailblazer (v6). Vehicle suddenly shifts itself into 4 wheel drive low gear without warning and without any action by the driver. Vehicle was brought to authorized repair center and dismissed as driver error. Shifting any vehicle into 4 wd low requires a definitive action by the driver of the vehicle. An action that the driver would know they performed. This is the 3rd such incident with gm vehicles my company has had. All dismissed as driver error. Investigative action needs to be taken at some level. Our local dealers and repair centers don't seem to be concerned.

car   Automatic Transmission problem 17
Failure Date: 01/03/2005

The vehicle switches from 2wd to awd on its own. This causes the vehicle to klunk and buck. It almost feels like someone is hitting the vehicle fom behind. This happened several times before we figured out what the problem was. Vehicle was repaired at the dealership. This was only one of twenty-one failures I have experienced with this vehicle since I purchased it in may of 2004- not to mention my severe back pain that is caused from the driver's seat. I have owned 9 vehicles, and have never witnessed such poor quality in a automobile. I am seeking a buy-back from gm.

car   Automatic Transmission problem 18
Failure Date: 09/10/2004

When accelerating from a stop drive train hesitates and engine comes to a near stall, and then accelerates. This does not occur on every start, randomly. Took vehicle into dealer who stated that it was normal for the type of drive train . Then the dealer reprogrammed the vehicle. After one day of driving the problem has begun again. This hesitation is very dangerous crossing traffic and in intersections.
