Loud noise in transmission this after 30,000 miles on a totally rebuilt transmission of my 2002 Chevy Trailblazer.

- Huntingtown, MD, USA

Pulling onto the highway, when transmission popped and began to whine. Reverse gear lost and stuck in 1st gear. Took to dealer where diagnosis was failed (stripped) reaction sun shell. Fortunately vehicle was traveling at low speed. Concerned that failure could have occurred on the highway at greater speed. This vehicle was never used for towing or subjected to any abuse whatsoever. This is a common failure in the 2002 models built during a certain time period. Dealer gave some cost concession on transmission replacement, but unwilling to admit component weakness. Called GM customer assistance line with no additional support.

I have a Chevy Trailblazer ltz 2002, "bought it brand new" excellent condition 75,000. I had a transmission flush done at 50,000 miles as requested. I get oil changes done every 3,000 miles. On August 5th 2007 I noticed transmission fluid splattered all over the under carriage of my vehicle and the back window. Took the car to a my mechanic who recommended I take the car to transmission specialist "amoco"so I did. Need my transmission rebuilt, fluid leaking out of air port in transmission, the drums defective.

Went to get gas for my 2002 Chevy Trailblazer and we I finished and I started my car I put it in reverse and heard a loud clunk noise and then the truck would not go into reverse. Then I put it in drive and heard a lot of grinding. I called GMC and they know the Trailblazer has a defective transmission and now that I call them with my problem they tell me that I just need to get a GM diagnostics test. Done and it just another way for them to get money out of people.

As my wife was pulling out of an intersection the Trailblazer may a loud sound and then started making a loud whining sound that got louder as she drove and had no power and would not shift and then lost reverse. I contacted GM after I found that several people have had the same problem they told me to take it to a GM garage and have it diagnosed and they would be in contact with me they finally told me that they could not help me because 1st I did not buy from a GM dealership, 2 I did not have my service and maintanance done by a GM garage and 3 because I was a second owner of the Trailblazer. So intern I had to pay $2730.27 to get the transmission replaced.

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.

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.

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 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.

2002 Chevy Trailblazer, slips out of gear, 1,2,3,4. and slams back while in operation. Consulted dealer, dealer said no recalls available. This happened 3X's. we stopped driving vehicle. On second incident a qualified individual said that there are issues in the transmission. Dealer still said no bulletins on this vehicle at large. Dealer stated that I take the vehicle to the vendor in which they do business with for inspection. Vendor who is repairing vehicle claims a clip or spring slipped out somewhere destroyed come major parts and also the casing. I have asked vendor to hold all parts. So far this episode is very costly.

- the contact owns a 2002 Chevrolet Trailblazer. The transmission was slipping gears. The contact stated that he had the original transmission replaced at 8000 mile by an authorized dealer, and now was experiencing the same difficulty with the gears slipping down speeds, and the transmission not engaging. The contact said that this happened often at 45 mph, and the weather has not been a factor. The contact stated that instrument panel lights turned off for a day on 1-3-07, and when the instrument panel lights turned back on the air bag light stayed on. He has had the vehicle fixed three times for the instrument panel lights turning on and off.

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.

- while driving the contact stated that vehicle seemed to shift into neutral and he couldn't get it to go faster than 25 mph. The contact has had the transmission repaired once before. The consumer stated the transmission failed twice. Updated 02/27/07.

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.
