Without warning car would not accelerate when applying pressure to gas pedal, the motor would just rev up. I had to shift automatic transmission into lower gear to get it to go. I was able to drive to dealership by manually shifting transmission. Service department inform me that transmission was shot and would need to be replaced for about $3,000. 00 dollars. My 2006 chevy Trailblazer has always been service at the same dealership and only has 28,783 miles on the odometer; I did not think that the transmission would fail with such low mileage. Gm did say that they would cover the parts but I would be responsible to pay for labor. I realized that chevy did not offer 100,000 mile power train warrantees on Trailblazers until 2007 but I believe that the transmission was defective from the start and chevy should be responsible to cover replacement cost.

2005 chevy Trailblazer. Bought the vehicle used in 2008 with only 33868 miles on it. Have 78158 on vehicle now and last month had to have the radiator replaced and transmission rebuilt. The place that did the repairs told me he gets about 3-5 Trailblazers a year with the same problem. He had 2 folks call about the same issue while mine was on the rack. Seems the radiator develops a small leak in the system that cools the trans and causes the transmission to fail. Had no real issues until last month when vehicle would not come out of 3rd gear. Could put auto transmission in to 1 or 2 and then be able to take off from dead stop and shift into drive to get the vehicle home and then to shop. Have looked online to see if there was a recall on this issue and there has not, but appears there have been other complaints about this issue. Total cost for vehicle repair was $2,814. 17.

Very hard, shocking 2-1 (maybe 3-2?) downshift after long drive as in 2-3 hours or under heavy load. Such a hard brutal shift can lead to an accident. This is a very serious situation and it feels like you have hit something solid like another car. It is hard enough to completely jar occupants and dislodge glasses off of your face. You immediately lose about 5 mph. Feels like it could cause complete transmission failure. It is very difficult to recreate this failure and it is so scary that you would not want to do it again.

We were driving on I-85 in virginia with cruise control on when the engine started racing. We limped into a service station at the next exit to have the Trailblazer looked at. We only had 1st and 2nd gear remaining on our transmission and had to have the SUV towed to the next major city and spend the night until the dealership opened on Monday. The end result is that the transmission failed at less than 64,000 miles. I was told by the dealership that the transmission housing essentially disintegrated and there were a lot of metal fragments inside the housing which were a major factor in the transmission failing. This level of catastrophic failure of a major drive train component should not occur at so low a mileage. We, as the consumer, were forced to pay $3200. 00 for a new transmission. Plus the costs of hotel rental and a rental vehicle to return home and missing work to address this issue.

Transmission on my 2006 Trailblazer failed at 44,000 miles. The failure caused the vehicle to roll backwards almost immediately. The vehicle would only operate in 1st and 2nd gear. Dealership inspection indicated that the transmission failed prematurely but had no explanation as to why.

2002 chevy Trailblazer - we had the transmission in our 2002 Trailblazer replaced in sept of 2006 because the sun gear failed and ruined the transmission. This truck has not towed anything. Now 35000 miles later, the same problem. This is the second transmission that had to go into this SUV with the towing package. We don't tow anything and yet the transmission fails from highway driven miles. This is obviously some type of defect after researching the internet, I have found many people having the same problem. I am tired of wasting hard earned money to pay for a manufactures faulty parts. They even have a service bulletin stating a potential problem with the part and don't do anything about it. I am tired of paying 2200. 00 + to correct their problems. When the transmission failed again a few days ago, my wife was nearly run into by the car behind her. I am seriously considering legal action.

After doing some research I am encountering a problem that seems to be out there a lot. I have a 2005 Trailblazer and my forward gear stopped working at 80k miles. I think is a much too new car to encounter a transmission failure. There is obviously a problem when I have read pages and pages of this same issue. Gm has to step in and tell me something my dealer estimate this to cost me a min. $3,200. 00 in this economy or any that is a large expense to encounter with no warning or previous problems. I hope the gm will have some answers and do the right thing! this happened to me on the van wyke expressway in rush hour many of us could have been hurt or killed! thank you.

Failure Date: 09/06/2008

Rented 2009 Chevrolet Trailblazer SUV from national car rental on 8/31/08 with 436 miles on odometer. Drove approx 800 miles over a period of 7 days. On 9/6/08, while driving on I-75 southbound at 70mph, vehicle shifted itself into 3rd gear, would not go into 4th or overdrive. Rpm's at 70 mph were approx 3,500. Pulled off road at interstate exit, transmission made a "clunk", jolting me and my wife rather intensely. Topped off the fuel, quite gingerly began our trip again. As vehicle reached 45-50mph, it downshifted itself into 3rd gear, jumping the rpm's and causing the vehicle to lurch harshly. Called national, requested they "talk us in" to saginaw, mi office for vehicle exchange. National rep told me she "could not read a map" and "can't tell what exit you should take to get here". We once again pulled off the road at an exit, slowed to a stop, put vehicle in park while attempting to locate a national office. While on "hold" with national's roadside assistance dept. , decided to try to get on the road again. Reached 40mph on I-75, when transmission completely failed. Motor revved when throttle depressed, but no forward motion occurred. Pulled off in emergency lane (narrow, next to a steep ditch), and were stuck there for nearly two hours while national performed a "tow-exchange". Eventually, another vehicle was brought out, but not until after we were stuck with huge semi tractors running 80mph past us for two hours, and having no means of shelter from the potential of becoming "roadkill"!! failure of transmission was unprecedented. Vehicle drove normally until it would not shift into 4th / overdrive. Failure was progressive and severe thereafter.

Failure of transmission on 9-3-08. Near collision with oncoming car because of loss of power as I turned left and tried to accelerate across the center line. The car would no longer move forward or in reverse. The car was towed to a transmission shop. They told me that it was the failure of the sun shell, a $39 dollar part. The entire ordeal cost me over $3600. 00 and climbing. The failure of the sun shell sheared off the cheap gears and the fragments filtered through my transmission causing more damage. My car had 76,094 miles on it at the time. The owners manual states that service for the transmission is not due until 100,000 miles. I thought I was buying a dependable car. This, I consider a major safety issue. If I was in traffic on the freeway and the transmission failed I would have been in serious trouble. I can only imagine what would have happened if was in the path of a semi truck. In the name of safety and the consumers pocket books who fund this engineering gaff, I think this issue should evoke serious consideration by the NHTSA to enforce a recall of the sun shell transmission part in all gm cars.

2003 Trailblazer transmission failure. Driving in the neighborhood (25 mph) heard a load clunk ( like something either hit or fell of the vehicle), then a high pitched whining sound, got the vehicle home (11pm). In the morning, to take the vehicle to be looked at found that I had no reverse, had to push it out of the garage. I have a extended warranty, but have given firestone permission to replace with a rebuild unit from gm. I do not know what my warranty will cover, but believe that gm should foot the bill, since this had been a reported problem for this transmission for years.

With no prior warning of defect, my 2002 Trailblazer would not accelerate while trying to merge into highway traffic. After initial look through for any obvious signs of what may be wrong, I was unable to drive my car and had it towed to nearest dealership where a transmission failure was quickly diagnosed and I was quoted a repair cost of just under $5,000 !!! my wife and I think this is pretty odd considering the regular maintenance and absence of signs of trouble, so we researched the internet only to find out that transmission problems (particularly on 2002 Trailblazer) are very common. It is believed that general motors is very much aware of this and the phrase "silent recall" kept coming up.

My 2002 chevy Trailblazer has had multiple drive train/transmission failures. It currently has 99000 miles on it and has been in for transmission complaints/work on 5 separate occasions. The last occasion being Nov. 28, 2007 at which time the car would roll backward while in park. Upon removing the transmission pan metal shavings were found. Currently this vehicle is at the dealership awaiting service/ call back from general motors corporation customer care as to whether they will cover failure due to the warranty of 5 year was up 8/31/07, with some transmission parts warranted from repair at 90,000 miles. However, the chevy service garage cannot guarantee that it is the previously repaired parts failure, therefore cannot guarantee coverage under warranty. I have 2 small children that are with me daily in this vehicle, I have had to have it towed due to transmission failure twice and now the vehicle rolls out of park. These aforementioned facts make me fear for the safety of myself and my family in this vehicle.

I have a 2002 Trailblazer. The transmission has failed twice since I bought it. The first time it was at 26,990 miles and the second time it was at 61,062 miles. Both times the transmission failed it was without any warning while I was driving it. The transmission would not move from 1st to 2nd or 2nd to 3rd unless I took my foot off of the gas. In both instances I also lost reverse. The first time it happened I was lucky because it was under warranty. The second time it happened it was 2 months and 1,000 miles after my extended warranty expired. The dealership quoted $2,038 to fix it (not replace it) but offered me a 10% discount. I didn't have a choice because I needed my vehicle. Since then I have found that this is a frequent problem that gm is aware of however they will not make a recall. What are my options? this is definitely a safety concern as there is no warning when the transmission fails.

In April 2007, the '04 Trailblazer's transmission failed. At the time the vehicle had less than 50,000 miles. I drive the car very well - mostly highway miles as I commute for work - and the vehicle had never been used to tow. The transmission was repaired at a Chevrolet dealer, and less than 2 months later, the transmission failed again. I am very unsatisfied with the quality of this vehicle.

While driving I automatic transmission failed to work in the drive position. It was taken to dealer for repairs,where it was found that a complete failure of transmission occurred. The vehicle was safely stopped on the side of the road. Their were no injuries, but under different circumstances this occurrence may have resulted in severe injury or death. The vehicle had only 51,653 miles at the time of the incident. The transmission was overhauled and the vehicle was returned 5 days later. The required first service of the transmission was not scheduled until 100,000 miles.

2002 chevy Trailblazer transmission failure. I was driving vehicle, stopped at a stop sign and when attempting to drive, vehicle wouldn't move. I only had a 1st and 2nd gear, no reverse, drive, or 3rd gear at all. I have researched this issue and found hundreds of similar complaints, some were near serious consequences. Public consensus seems to be that gm is aware of the problems (due to hundreds of phone call complaints) but refuses to recall transmissions until NHTSA forces them to. Gm has been offering a 30% rebate on the repair costs, which exceeded $2,000. 00 I haven't yet spoken to gm, but am sure to get the "run around". I have to have the vehicle towed to a repair shop today.

2000 chevy Trailblazer had transmission failure with only 71,000 miles. Dealer claimed that it was a "natural thing" for these transmissions to fail. Gm customer service refused to assist even though hundreds of these type complaints have been filed. An immediate recall should be imposed on Chevrolet for distributing faulty transmissions that fail even before maintenance is due. I would not be surprised to see a class action lawsuit over this due to the high number of transmission failures. Someone will eventually get severely hurt or even killed because there is no warning before the transmission breaks.

The contact owns a 2002 Chevrolet Trailblazer. On January 17, 2007, the contact heard a loud boom and the transmission failed while driving 10 mph. He then coasted the vehicle at 5 mph to the nearest shop. The mechanic stated that the actuator fell from the transmission and the entire transmission failed. The contact was also informed that all four tires were rotted and needed to be replaced. The engine size was unknown. The current mileage is 28,000 and failure mileage was 22,900. The consumer stated wants to gm to pay the cost of repairs for the defects in the vehicle, however consumer is stating not responsible for defect the part provided is not the same part stated in the recall. Updated 06/08/07.

2002 Trailblazer transmission has failed twice . First failure was at 38,000 miles and second failure is at 83000 miles. The failures happened both times at the exact same location as I was entering a major highway from a stop sign. Purchased a new transmission at 38,000 miles costing over $1300 dollars to get a new transmission vs. A rebuilt one. I believe gm know there is a problem with this vehicle however , fail to fix the problem. I am afraid this vehicle will result in harm or death to my family if the transmission keep going out this way.

Transmission failed. Diagnosis was reverse sun shell failure (just like all the other complaints listed on this site)! gm refuses to offer any cost assistance with the repair or acknowledge that there is an obvious defect that should be recalled!!!.

Transmission failed in 2002 Trailblazer on 12/21 with 93,000 miles while traveling with family on christmas weekend. Left stranded on highway and had to be towed. Will not go in reverse and will not go into second gear. Mechanic said gm parts are inferior and he will replace with aftermarket which will be much better. Transmission should last much longer than this. I have had vehicle with 250,000 miles on the odometer and not had transmission problems. Gm should admit there is a problem and recall this transmission.

Summary: -2002 Trailblazer lt 2wd -transmission failure at 78,000 miles -near accident with two children in car ages 2 and 7 -major repair cost -significant safety problem -multiple listings of identical failures (sun shell/ reaction gear) planetary system. -reportedly known defective and (under designed) part. This will be the NHTSA's responsibility to investigate and sort out. -some reports of a "silent recall" however never acknowledged with my conversations -no warning of oncoming failure -owners manual doesn't recommend any transmission service until 100,000 miles -never towed anything -wife driven/ garage kept -significant engineering accomplishments in transmissions have been made in the past decade with materials and lubricants. There is absolutely no reason a tranny should fall apart on an automobile towing or not under 100,000 miles especially if your following the manufacturers maintenance recommendations. -gm covered 30% after lengthy time. -technician described failure "when we see these problems its almost always what we call the sun-shell grenades" now, since you limit your description to 2000 characters which doesn't allow a complete description I will leave you with the summary and give you the location of the full report which I hope you take the time to review because of the safety problem. .

Failure Date: 05/26/2006

I own a 2004 Chevrolet Trailblazer and the transmission recently failed, due to causes unknown. This concerns me because I only have 54,000 miles on my vehicle and it has received all scheduled maintenance. Also I've done some research to find out that is a recurring issue starting in 2002 with the Trailblazer. I am going to contact Chevrolet for repair but my warranty is expired and I am sure is will have to pay for all repairs.
