#419 of 498 2002 Chevy Trailblazer Tranny Problem by timb2

Nov 21, 2009 (6:16 pm)

I have an 02 Trailblazer with 160k miles. For the past year when I step on the gas from park or being stopped it goes well up til 25 to 30 mph, then it does not seem to shift into second gear until the rpms get up to about 3500 to 4000, The past month it has not wanted to shift at all into 2nd gear
My mechanic said there are shifting solenoids that may be bad The tranny shop said 1800 dollars and I will rebuild it
I just replaced the spark plugs and the problem has seemed to have gone away where it wont shift into 2nd gear at all and back to the first situation
My question is what is going on with the transmission
Two local dealers of G M Vehicles say the transmission is verry tough and they have not heard of this happening any Ideas???

I have a 2004 TB Ext and just got a call from my friendly neighborhood mechanic who said my front differential is fried and will cost $2000 to replace. I have not owned an american car for many years and now I know why. I have a Toyota Sienna with the same amount of miles, it's a 1999, and have never had anything more than routine maintenance. Anyway, thanks for the posts on this topic, at least I know I'm not alone. Could someone who knows clarify the relationship between a fan clutch problem and this front differential problem? Is there a relationship? My mechanic told me several months ago that my check engine light being on was caused by the fan clutch and not to worry about it as it is expensive and doesn't really effect much except maybe the gas mileage slightly. WHat do you think??

I take it it's 4wd since your referring to the front differential. There's no relationship between the fan clutch and the front differential. What happened to the differential to make become "fried"? Was all the lubricant gone?

I was wondering if you resolved this issue and what did you have to do? I am having the same problem with my transmission on my 03 TB. I had the fluid and filter changed about 5k miles ago and the problem just showed up where it wants to fluctuate rpms from 2k to 1.8k and will not hold steay. Thanks

I never did resolve it. I've put another 4k miles on since my last post and it hasn't gotten any better or worse. I made the trip from NY to FL with no problems. The issue seems to not be apparent over 70mph. I did talk to a tranny shop for a bit about it and it sounds like it is more of an annoyance than a real problem. Eventually it sounds like it should be rebuilt, but he didn't think it was going to leave me stranded. Your's sounds to me like the same thing.

#425 of 498 Tanny slips when warm 2004 trailblazer by mrjmarco

What would cause my transmission not to slip when its cold, but once warmed up it completely slips and want drive in any gear. If I pull over and let it cool off it will drive a little bit again and then completely not go into gear.

#426 of 498 Tranny Lines Rusting by tb4me

Hi all been a long time since I posted. Happy Holidays!!!
 
228,500 miles on the original tranny--just let loose 2 days before x-mas--ouch!!!
 
I wanted to let you guys know to start checking the trans cooler lines as mine have rusted out--yesterday. What a mess!! caught is soon enough not to fry the new trans. It's an ongoing problem that GM fails to recognize yet. Go to the NHTS website and you will find complaints galore on this issue. I'm having new lines installed now.
 
Still truckin--02 TB LT.

Trust me, GM would not have done anything for you. I did everything they told me to do regarding my transmission - same thing...sun gear...mine had only 57,000 miles on it. I took it to a GM dealer/garage and pretty much jumped through hoops for them. They put me off for over 3 weeks saying that they had to have somebody go check out the car, blah blah blah, and they ended up denying my claim because of the age of the car - it was a 2002, and the mileage. I fought with them because all of the transmission guys we spoke to (even the ones at the dealership) said it's practically unheard of to have an '02 with only 57,000 miles on it to have transmission problems. GM pretty much told me "tough luck" and that was that. Then, I got a call from GM about 2 weeks after I had already had my car fixed, and they told me that they couldn't be more sorry about the way I had been treated and that they were going to try and "help me out". Long story short, they kept me hanging for another 3 weeks and came back with the same decision that because of the age and mileage, they would do nothing for me. Why did they bother calling me and initiating this all over again if they couldn't find a "better" reason? So aggravating. Bottom line...dump GM and buy foreign.
