#41 of 422 Re: 04-05 Transmission Problems? [57chevrolet] by imadad2 May 24, 2005 (11:48 am)
Replying to: 57chevrolet (May 09, 2005 1:04 pm) I own a 2004 LS EXT. No problems at all. I only have 10K on my SUV, so it makes me wonder what will happen in three or four years. I also read that the tranny issues were resolved after the 2003 model year. We will see. Make sure you drive the Trailblazer you are wanting to buy in high speeds. Wind noise may not suite your tastes. A lot of people complain about it here.

I heard a funny noise, then it was like I put the truck in neutral and was reving the engine." In all the years that I worked at a parts store and worked on poeple's cars, I have never even heard of a bad water pump causing the car to do this. When water pumps go bad, they leak coolant all over the ground, or the bearings will go bad and they will leak coolant, squeal bad, then sieze up.   As far as the other transmission problems, if you get things repaired when problems are first noticed, you generally don't need the whole transmission to be replaced. On the newer electronically controlled transmissions, the shifting is controlled via solenoids, which have generated numerous TSBs and changes over time. Also, what makes most of the transmissions go is lack of fluid pressure holding the clutches engaged. The solenoids and other parts of the valve body are responsible for this.   My own problems revolve around an S-10 that has a bad launch shudder and a shudder at times in other gears. I have found out from a TSB that a bad ground could be the problem, and from buying a transmission book, found out that there are literally 100 changes that GM has made to the same transmission in 6 or 7 years. I have also found out that most of these problems are cause by lack of fluid pressure.   If you get a transmission fixed or replaced, make sure that they are updating it with the latest fixes and that they have checked all applicable TSBs from GM. Also, as was my experience just yesterday, there are only a handful of service people who will take the time to help you and speak to you. The rest think you are dumb and don't want to waste their time. (I have several letters going to dealership GMs)
#43 of 422 Re: 03 TrailBlazer Transmission Replaced [bpurvis] by 2002envoyslt May 30, 2005 (11:06 pm)
Replying to: bpurvis (May 23, 2005 2:53 pm) I own a 2002 Envoy 4x2, automatic trans w/ 44K miles. Need some expert advice. I was driving this weekend and had some issues. On one occasion, I stepped on the gas to accelerate but only the RPM went high-there was no acceleration. I then tried again, and it began to accelerate. But from that moment on, I notice the vehicle is having problems shifting from 1st to 2nd and the biggest problem…I have no reverse. I checked some forums and noticed that other people have some similar problems, but I didn’t see any solutions. I tried adding 1 quart of transmission fluid since it was a bit low, but that didn’t work. I noticed some people had parts replaced...can you tell me the parts, costs and if there were warranties? Any help would be greatly appreciated, thank you!   Replies to this message: jgrisham (Jun 16, 2005 3:14 pm) 2002envoyslt (Jun 16, 2005 4:33 pm)

Replying to: skmaher (May 18, 2005 4:22 pm) I purchased a 2003 Trailblazer and have just reached 80,000, and now my transmission has gone out. Yes, I am interested in filing a class action lawsuit. Replies to this message: 2002envoyslt (May 31, 2005 1:39 pm) raustin (Jun 16, 2005 4:12 pm)
#46 of 422 2002 Envoy Transmission problems by 2002envoyslt May 31, 2005 (1:39 pm)
Replying to: achevy (May 31, 2005 11:25 am) I had a previous post and just got word from the dealer that he can A) replace the tranny with a certified tranny warranty w/ 3yrs, 100,000mi ($3200) B) tear into the tranny find out the problem and try to fix it (approx. minimum of $2100, if more than $3200 he'll put in the certified tranny and charge for tearing the first tranny, approx $4300) Is there anyone out there with an option C that can make this problem a little less expensive? Please help...
#47 of 422 GMC Yukon Transmission Failure by mandrake4565 Jun 02, 2005 (6:14 pm)
To any one with a similar problen I would like to her from you. I own a 2002 Yukon, It has 44k miles on it and no extended warrenty. I do all of the maintence on it myself and I am very meticulous with it. I t has never towed anything other than my 35 lb mountain bike or been off road other than a non paved parking lot. I experienced a complete transmission failure while driving approximatly 70 mph on the highway. It sounded as if the tranny exploded. The tranny basically blew up 4th gear and took out the rest of them with it. I had it towed to the dealer, they told me that it would cost $2,500 to rebuild it and $3,100 for a remanufactured one with a 3 yr 50k mile warrenty. I find it funny that the remanufactured tranny carries a better warrenty than the original. After arguing about the tranny blowing at 44k miles with customer service they offered to pay for half of the rebuild $1,250 only after tearing down the tranny to see if I did anything to cause the failure. They found that I wasn't at fault. I still didn't think it was fair so I bitched some more and they said that I would only have to pay for a $500 deductable to fix it. I find it funny that in April that they recalled some 2004 full size suv's and pickups due to a faulty pump that may prevent lubrication from reaching overdrive meaning 4th gear gearset bearings. It is just making me angry that I even had to pay $500 for the same problem.
#48 of 422 2002 TB Transmission problems by kwinters Jun 02, 2005 (8:02 pm)
I too had transmission problems on my TB. I had just turned onto a residential street, started to accelerate and the loud screaming sound started. I pulled over immediately. My husband then drove it gently to the dealership (thinking it had to be a recall issue!). Mine has 51k, never towed anything, 95% highway driving so it shouldn't have gone out. It was the Sun Shell Spline. The dealership assumed that was the problem when we took it in, but wanted to charge us $455 just to pull the transmission to be sure. We took it to a local car repair shop and saved some money. However, when I got it back, it would "kick" into 2nd and 3rd gear, so the solenoids had to be replaced. After $1300 it's now running smoothly. Just got it back today, so not real comfortable with it, ESPECIALLY after reading these posts. They definately need to reimburse us for these problems! Good luck!! Replies to this message: gmboy (Jul 23, 2005 10:43 pm) 4x4dman (Jul 03, 2007 2:19 pm)
#49 of 422 2003 GMC Envoy Trans. Failure by henson3 Jun 03, 2005 (5:32 am)
Just like a lot of you have experienced, my Envoy which has 61,000 miles, just blew the transmission. Had been experiencing a clunking noise when coming to a stop and also when accelerating. Thought it might be universal joints but quickly found out it was the tranny when my wife couldn't get it into reverse and it would only go forward. Took it to a nationally known transmission shop which told me the sun gear was gone and that the rebuild would run me around $2,300. I don't know that much about trannys but after reading everyone elses problems it appears that they are being honest in their evaluation. I love the envoy but am considering going back to an Outback. They are smaller but one thing is sure the Japanese usually don't build junk. Thanks GM you've made me a believer.
#50 of 422 My rear end is starting to shake!!!! by ndmike88 Jun 03, 2005 (8:46 am)
Backing out of my parking spot the other day, I noticed that when I put the TB in reverse the back end was shaking slightly. Almost felt like 2 flat tires. Put it in drive and the shaking stopped. Did the same thing this morning leaving work....Is my transmission starting to go? It's an '03 LS with 19,100 miles. Never abused, or had anything towed. ??
