I still run it, because if you mix it with green it will turn to sludge, so I run it as a just in case, but I flush it yearly.

 

39k on my 5.3
175k on my 3800


My transmission went at about 150,000 miles. No real warning signs, it just stopped shifting into overdrive and started to whine.

 

alright thanks guys

 

After flushing it, I would recommend avoiding Dex Cool and going with the regular green coolant. Prestone or Peak should be fine. Make sure you use the full strength version and of course mix it 50/50...water and coolant. Make sure you get all the bubbles out of it so you don't experience overheating. That is the hardest part of the job.

 

3800 with almost 87,000
The only "problems" I've had with mine is my 'speed sensor' went bad (the car would be off, key not in the ignition and the speedometer would still say around 50 or so), that got fixed. Another thing is when I turn my highs on all my lights, including my dash lights, shut off and the only thing I'm left to see with while drivin down wooded back roads, is my fogs... SUCKS! And the last thing is my sunroof, at times, decides it doesn't want to close so I have to hit the button a million and one times for it to close! And I had to change my battery in September of '09

 

i got that problem with my mirrors, anyone know what thats all about i just have to keep hitting the button

 

the relay is going bad for the mirrors wht02monte. oh bambi88 change your relay for it as well. it is usually one of three things 1. switch. 2.relay. 3.motor going bad. its usually the first two that goes first and they are the easyest and cheaper to replace. than replacing the motor

 

oh i have 69k on my monte there were three things that were happened to mine 1. some one stole my 17 stock aloys had to get the steel rims i still hope its temporary. 2. id the coilpack went on mine. 3. the maf went bad and i got the ss monte carlo maf

 

3400 just rolled 60k

 

are you talking about the lights or the sunroof? Ive taken it to a shop for both of these to be fixed, they said they fixed it but they didnt touch anything.
