    Transmission fluid flush/change at 160,000 miles

    Looking at a 2009 Tahoe LTZ. Has 162,000 miles. Maintenance has been kept up with as far as oil changes and things. In great shape! Transmission fluid has not been changed. I’ve read where some say at this high mileage don’t do it but some say you still should. Should i walk away on this...

    2011 Tahoe Z71 with 129,000 miles. Buy or no??

    Looking at a 2011 Z71 with 129,000 miles. High miles for its age but seems to be taken care of based on the Carfax. Reg oil changes, transmission fluid changed, etc... they are asking $16,987. Also noticed on the backup camera there were no direction lines. Basically no lines to guide you...

    whistling/Humming sound at 40mph, only during acceleration

    No clunk, just a whine. Doesn't do it in neutral only when I reach around 40mph during acceleration. If i let off of the pedal it stops, but then when I press on the gas again it starts. Its literally just during acceleration after reaching 35-40mph

    whistling/Humming sound at 40mph, only during acceleration

    I have an 03 z71 and i get a humming/whistling sound when I get to around 40mph. Only hear it as I accelerate. If I take my foot off the gas the noise goes away, then comes back as I accelerate. I've done some research and some say it could be the carrier bearing, or a pinion bearing...

    Heat and Air problem...

    Thank you for the reply!!!! When I have the AC on it blows cold, very cold. Just cuts in and out so I have to turn off the power, wait a few min and turn it back on. So if I'm correct in what your saying, I need to replace the control unit?

    Heat and Air problem...

    Also would the refrigerant cause the heat to do the same thing? Cut in and out?

    Heat and Air problem...

    So the low refrigerant can make it cut on and off? Were you able to add refrigerant yourself?

    Heat and Air problem...

    I have a 2003 z71. My problem exists with both air conditioning and heat. I hope I can explain it to where it makes sense.... As i'm driving the heat/air (depending on winter or summer) will be fine, then it just cuts off. Still blows a little but not at the setting its set on. If I turn it...

    2003 Z71 air conditioning problem

    Air blows cold. However, as I'm driving the air will basically stop blowing through the vents at a normal speed. It will barely blow. I can turn it off for about 2-3 minutes then turn it back on and it will blow like it should. Blower has been replaced, but still cutting in and out randomly...

    buzzing sound in gauge cluster...

    Have an 03 Tahoe and am hearing a kind of loud buzzing noise that I think is coming from the gauges. Looked into it and some say could be the stepper motors. All my gauges work, but the noise is annoying as hell! Should I take to the Chevy dealership to get it looked at?

    Spill/leak after fluid change???

    Had all fluids changed: Transmission fluid, transfer case fluid, and differentials. Took it home last night and had a transmission fluid spill/leak down my driveway. If a new gasket was put on, does it take time for that to set in??? It was fine before I had the fluids changed

    Just bought 2003 Z71 w/145,000 miles. Fluid change question...

    Bought a 2003 Z71 Tahoe. I don't know if the transmission fluid, transfer case fluid, differential fluids, etc have been changed or replaced. Should I go ahead and do this since it has 145,000 miles on it? Also do any of you recommend just going to a Valvoline to have this done?? Thank you
