I own a 2002 trailblazer and bought it new in may 2002 and purchased the extended warranty 5 years or 50,000 miles. The other morning on my way to work my car would not shift to the next gear automatically. This happened with no warning. It did this the whole way to work. I was concerned at that point that there was a problem with the transmission. When I came out of work to leave for the day I needed to get into reverse to get out of my parking space and my vehicle would not shift into reverse. At that point I knew there was a real problem. I checked my transmission fluid and it appeared to have been a little low so I added some fluid and that did not make difference. At this time the person who was parked in front of me left so I was able to get into drive and I drove carefully home. When I called the dealer and asked if my vehicle was still under warranty they checked and it was not. I have 58,000 miles on my car and my warranty was for 5 years or 50,000 miles. So at this point I had no other choice then to take it to the dealer or another shop to have it looked at. I chose to take it to aamco transmissions since my family has used them previously for other transmission problems. The mechanic there told me that they would do diagnostic tests, a test drive and then check to make sure all connections are good. Within a couple of hours he called me to let me know that my problem with my transmission was definitely internal and they would have to rebuild it. He told me that I had no 1 2 3 shift and no reverse. Once they had taken it apart he called me to give me the damage. The cost of the rebuild with several parts needing replaced this is costing me $2500. These are the parts that needed to be replaced, torque converter, drive shaft, transfer case fluid, steel plates, drive shell, update pumps, reactor shaft, thrust washer and epc solenoid.
2002 Chevrolet Trailblazer transmission complaints
Page 8 of 11: complaints 191 to 220 of 310, newest first, as owners wrote them.
Car starting making a whinnying noise. I then turned around and took to car to the dealership for repair, approximately 10 miles. Their investigation found it was the transmission , only 84,500 miles). At this point, I will have to authorize them to make the repairs , approximately $2500. After reading several message boards, it appears that this is a common problem that gm addressed on the 2003 model. Apparently, part of the transmission on the 2002 could not stand the heat. Gm needs to fix this problem and issue a recall, and behind their product).
Right front outer shaft seal failure. This is a light truck/SUV that seldom sees use off of a paved road. The "right front outer shaft seal" should not be failing at 57,326 miles. "goodwill warranty" covered portion of replacement cost.
4 w/dr light goes to 4hi/ all wheel dr/4 low without warning at anytime. The computer mode was replaced once under warranty at the moment it doesn't seem to be actually shifting. Also had a loud jet sound coming from the engine as if it was laboring and had to have the fan clutch assembly replaced @ a cost of over $800.00 .
Vehicle was not shifting properly transmission failure ( sun shell spleen the works). Had an inspection and had to have new sun shell spleen, reconditioning of transmission. $ 3000.00 to fix, I see many complaints on the 2002 trailblazer. This should be looked into, I called the manufacturer to tell them about the failure and they e-mailed me and thank me for the e-mail. My vehicle only had 49,665 mileage. I should have saved the parts they were in very bad shape. This failure was without any notice.
I had a problem with the engine slipping on my 2002 chevy trailblazer. I took it to the dealer and they said it was the 4 wheel drive button and replaced it. I am now having another problem with the transmission. When I start it up the brake light and ABS light stays on. When I put it into gear the engine keeps winding up and will not shift. I then have to pull over and turn the vehicle off then start it back up. This problem occurs on a daily basis.
We own a 2002 chevy trailblazer 4wd with 57,000 miles. On the date of the incident, a clunk was heard from the transmission and the transmission would not shift properly and there was no reverse gear. The vehicle had to be towed to the dealer. After inspection and road test, it was determined that the "sun shell spleen" had stripped and the sun gear and sun shell drum had to be replaced along with a reconditioning of the transmission. This repair came to the tune of 2022 dollars. Our service manager was able to have the factory cove half of the repair as a "goodwill gesture." I am also an employee at the dealer and had access to repair information provided by chevrolet. Apparently, the material the original sun shell was made of was not able to withstand prolonged high temperatures that are found in the trans. For the 2003 model year and later, general motors made the sun shell out of a "more heat resistant material" which will "hopefully" prevent the problem from recurring. In my opinion, this is equivalent to general motors admitting that the original trans in our vehicle was of substandard quality right from the manufacturer. This problem has eroded away any confidence we have in gm and do not feel safe driving this vehicle for fear of the problem recurring in a much more dangerous situation that could lead to a loss of control and possible a major accident.
Sharp turn steering locks up. Passenger seat belt gets tighter and tighter doesn't release pressure. 4 wheel drive not working . Tapping sound in engine. The only thing the dealer has done is replace power steering pump and within 5 miles it was not working again.
2002 chevy trailblazer ls 2wd 4.2l has 79,200 miles on it driving in town, parked in a parking spot to drop wife off. Put truck in reverse to back out of parking spot. Hear a loud "pop" and now I have no reverse, no overdrive. Car goes to 6000 RPM before shifting intot he next gear. Take truck to dealer, cost is 1800 to fix the transmission, I call gm customer assistance, tell me there is nothing they can do for me. Sun shell gear is one of the parts that need to be replaced
My wife was driving her 2002 chevrolet trailblazer when the transmission catastrophically failed. The vehicle was towed to a dealer, and the diagnosis was "sun shell spline failure" in the transmission
When accelerating the SUV seems to stall and needs a while to pick up and this causes many noises to come out of the engine. This has happened since I bought the truck in 2002. Took the truck in many times and the dealership said its normal, but my sister purchased a 2005 trailblazer and when driving that the transmission is and sound excellent, unlike mine that souds like a semi taking off.
My trailblazer has 56,000 miles and the transmission has went out with no sign that it was going out not even a warning light inside the truck or a noise when driving or starting the vehicle.
My vehicle is a 2002 chevrolet trail blazer of which I purchased new. Since day one the vehicle has been plagued with a multitude of problems. It has had an engine replacement, clutch fan ($620.00), tail lights, HVAC controls $(200), exhaust manifold, recall items and now finally a transmission failure where the sun shell/gear let go costing me ($1858.03). Fast forward to today just 3 months after the transmission was "completely overhauled), the valve body id failing where the dealer has told me that "is not part of the 12 month, 12,000 warranty on the transmission."

Transmission failture
1. My car broke down on my way to work, approximately 27 miles into the trip. I turned onto a side street, and when I started accelerating, a loud screeching sound started as I entered 2nd gear. I immediately pulled over. 2. My husband gently drove it to the dealer and they assumed it was the sun shell spline. However, in order to find out, they wanted to charge me $455 to pull the transmission. We decided against it, fearing the high cost of repair and took it to a local mechanic. 3. Mechanic replaced the sun shell spline, pressure control solenoid and manifold pressure switch. Cost = $1,222.66 + $84.00 diagnostic at dealer. We have the sun shell spline. Repairs were completed on june 2nd. Then, on june 5, the condensor on the A/C went out. Took it to the dealer because chevy stated that was the only way they could help me (no help on the transmission). Cost to repair = $261.34.
Vehicle jumps into 4lo and 4hi at random. Dealership reprogrammed something, and problem continued. Dealer now guessing at problem. When the 4lo engages vehicle acts like brakes lock up.
'02 trailblazer-I bought the vehicle used at 30k. Every once in awhile when pulling it out of the garage the 4x4 selection lights would go out and the red "n" would flash. When I put the vehicle in neutral the red "n" would go out and the 2wd light would come on. At approx. 40k miles it did it one day when I was pulling out of the garage. Later that day I was just exiting the interstate and heard a loud grinding noise coming from the transfer case/transmission. The noise changed pitch with my speed. When I pulled over to the shoulder I put the vehicle in park and shut off the engine. When I took my foot off of the brake the vehicle started to roll down a hill. I re-applied the brake, started the vehicle and switched it from 2wd to 4wd then back to 2wd. The vehicle then was able to move and I took it directly to the dealership. After they looked at it the next day they said "could not duplicate the problem." they also said that the flashing "n" was not normal and to bring it in if it did it again. After looking at this site I am very concerned for my family's safety in this vehicle. I spoke with chevrolet customer service on 5/3/05 on this and another issue and was told that my vehicle VIN was not part of the list of those affected by this problem and that it would only be added if the dealership saw the problem.
Transmissions went out weeks after hearing sounds underneath the car, and hearing a loud poping sound. I had all of the recall problem, plus problems with my heating and cooling system controls going out on the high setting, problems with embrassasing squeaking noises coming from underneath the car. What really hurt me so bad is that the place where my husband and I work we build parts for general motors every day and worked there fo 22 years trusting that the first car that we bought brand new would be a gm product that I would be at least heard from the company and having them be concerend enough to help pay for my repairs or something, I only had the car for 2 and a half years.
Noises coming from underneath the SUV ,check engine light constantly came on and one night I was going around 55 MPH my 15 yr old daughter,we heard a loud pop it sound like we had hit something in the road so I stop to see what it was, we saw nothing but the squeaking sound from under the SUV got louder some day later jumped in the car started the car and there was that loud sound again only this time the SUV would not move in reverse I could hear some spinning like noise so I took it to a shop and I was told that the transmission was striped out in reverse, and that some shaft had broken or something, the mechanic also told me that he had several people come in with the same problem the same model trailblazer 2002 what hurt me so bad is this was my first brand new car, I only had it for two years, and if I every buy another car it want be from gm, I also had problems with my tailgate lamps ,windshield wipers,steering column.
We bought a new 2002 trailblazer. Never used the four wheel drive until it had 39,000 miles on it. At that time, found out we would need to replace a transmission module. This was replace about three months ago.*ak my wife was driving the truck down the interstate in two wheel drive. Without warning, she felt the vehicle lose power and slow down. She glanced down at the electronic switch indicator for drive condition. The indicator light was flickering between four wheel hi and four wheel lo. If there had been other traffic around, it could have been a serious accident since she slowed down under 40 MPH during this ordeal. I was driving the vehicle and was stopped waiting to make a left hand turn. The drive indicator, without warning, started to switch between two wheel drive, four wheel drive hi and four wheel drive low. I didn't move. After about 5 seconds, the lights stopped flashing and the two wheel drive indicator lamp was on. I proceeded to make the turn. The dealer (glenway chevrolet, cincinnati, oh) finds nothing wrong with the vehicle. Their suggestion: we start to replace parts, at our cost.
Fan clutch: took vehicle to the dealer because the vehicle was making a very loud clinking noise, which is coming from the front end of the vehicle. Consumer took vehicle in three times to dealer for this. Problem. Dealer stated that the clutch assembly fan failed.
2002 chevrolet trailblazer had problems with the transfer case control module.*mr the light on the switch did light signifying whether 2wd, 4wdh or 4wdl was operating. The transfer case did not switch out of 2wd into any other operating modes.
Shifted vehicle into reverse and heard loud bang. While backing heard grinding and scraping noise. Shifted into drive(forward gear). Hear grinding noise in drive. Taken to mechanic. Diagnosed with broken planetary gears. Parts available for inspection.
The vehicle locks itself into 4-wheel low, which caused the vehicle to go from 45 miles to 25 miles in a matter of seconds. There was no warning. Consumer has taken the vehicle into the dealer 10 times already. Consumer has had 2 accidents with the vehicle due to the vehicle dropping into 4-wheel low. Also, the air bag did not deploy. Consumer was injured.
Purchased vehicle 6 months ago from a dealer. It had 54,ooo miles on it and it now has around 60,000 miles.my hisband noticed that the transmission was not shifting properly at times, we mentioned it to dealer and they said that nothing was wrong with the transmission on our way back from town one day and before the day was over and we could get back home we had lost all but 1st and 2nd gears, took to our mechanic and transmission has to be replaced on this vehicle with only 60,ooo miles on it. Of course the warranty had expired, and now we are stuck with repairing a vehicle that should have been taken care of before this.
