I did have the filter changed at the time it was flushed. Can a tranny shop diagnose this with any confidence? I really don't think the tranny is slipping. It shifts firm in all gears. I don't want them to tell me it needs a rebuild if it really doesn't. What kind of repair bill can I expect?

you can take it to any mechanic with a diagnostic computer and it will give them a code. take that code and call dealership and ask what that code means. if it refers to fan clutch, you don't need trans rebuilt. most diagnostics cost about 30-50 bucks. good luck.

Well I had it hooked up to the computer and there were no codes, so I didn't figure it was the fan clutch, but I ordered one and put it in anyway. It really wasn't too bad to change. Unfortunately, but not surprisingly, it didn't change anything. I guess I'll have to take it to a tranny shop. I'm running out of time here before I take it on vacation. I like to put a few miles on a vehicle locally, before I take it on a trip to make sure everything is functioning properly. Do you think if the tranny needs repair, I can be confident that it will work properly and not leave me stranded? The shop I plan on taking it too seems pretty reputable.

I will take my truck to the trans shop and get the flush. I hope that works. They need to have a recall on these trans, if there are so many people having problems.

2002 Chevy Trailblazer Tranny Problem by timb2

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??
