You are in the Chevrolet Suburban & Tahoe
What is this discussion about?
Chevrolet Tahoe, SUV
Jan 12, 2007 (9:00 pm)
Does anyone know where the microphone for the OnStar telephone is located? I own a 2004 Tahoe Z71. They are probably all located in the same place no matter what year the Tahoe is.
Also I can't seem to get an answer from any auto parts store about the Transfer Case or the type of fluid to use in it. My manual says to use Auto Trac II and even gives a part number. Auto Zone, Pep Boys, Wal-Mart and Kragons, none of them carry Auto Trac II on their shelves and their computers don't give any information for the Transfer Case, etc. This is unbelievable. Does anyone know if Auto Trac II is the same type of fluid as your Transmission uses? My Transmission is supposed to use Dextron III. I might just have to go to the dealer and pay and arm & a leg for transfer case fluid it sounds like.
One last question? As mentioned above my Transmission uses Dexron III according to the manual. I've been advised by my brother in-law who's been a Mechanic for over 25 years at a Chevy Dealer that you have to use the right transmission fluid. He said that now a day’s there are several sensors in your transmission and they know if the type of fluid you put in it is wrong and could mess up your transmission if you use the wrong type. He said that just because it say's Dexron III doesn't mean that it's the right transmission fluid for your transmission. I bought some Mobile 1 synthetic transmission fluid at Auto Zone today. It say's on the back of the bottle that it's for Dexron III. It also say's that it is for Dexron II, Dexron and several other types along with being able to use in Ford, Chryslers, and several other makes. Does this sound right? Can one type of Transmission fluid be used as if it where several different types of fluid on several different makes of vehicles?
2004 Chevy Tahoe Z71:
1. OnStar Microphone?
2. Transfer Case fluid?
3. Transmission fluid?

fuel gauge was just hitting the red. I have gone well into the red many times before, then the light comes on. I have gone another 20 miles with the light on. Dont know why this time it was so off. Weird.

My 2007 Tahoe fuel lite didn't come on once but has since so not sure what happened. The range on the DIC is usually pretty accurate.

Did you ever get an answer to your question?
The reason I ask is because my 2004 Tahoe Z71 right side day running light also does not come on. I haven't taken it out to see if it is blown or not yet. I did take off the headlight assemble since it is only held on by the 2 pins. I attempted to pull the day running light assemble out, but couldn't get it to come out and I didn't want to break the plastic by forcing it out. So I've put it off for a day when I have more time to take it off with out breaking anything and when it's a little warmer outside.
Is this a common problem with this particular light? If so then maybe it should be recalled. Also if it causes something in the electrical system to screw up starting your Tahoe then I will just leave it as it is. Let me now if you figured out if your engine troubles are related to the light bulb replacement.
Anyone else out there that has also had this particular light that has stopped functioning pleases posts messages and let us know. If it is a problem with more than just 2 Tahoe's then something must be wrong and should be recalled.
#6146 of 6471 Heater Stopped Working
Jan 15, 2007 (3:53 pm)
I just had my Transmission fluid and filter changed. After about 40 miles on the road my heater started blowing cold air? I turned it of and on several times and it still just blew cold air. The outside temperature was about 39 degrees and the engine temperature gauge was reading it's normal temp of around 200 degrees.
I went into Wal-Mart and came out a couple of hours later. On the way home I turned on the heater and it is now working fine. I have driven it a couple more times since and the heater is still working as normal.
I was wondering if this could have happened because I had the mechanic put in Full Synthetic transmission fluid instead of just straight Dexron III and the transmission sensors were effected?
I've never heard of this before, but seems strange how it happened right after the transmission fluid was changed.
What ever the cause was, I pray that it doesn't happen again, at least not in the winter when the outside temp is running between 10 & 40 degrees.
Has this happen to anyone else, where their heater started blowing cold air for known reason?

Hey! on the right side, there is a rubber mat next to the radiator. Run your hand down it and it will have a access port in it. My hand barely fit in it. you can pull the bulb fixture out that way. The wire it too short to pull the whole thing out so you will have to use one hand to hold the base and pull the bulb out at the same time. It can be done, just have to have strong dexterous fingers.
#6148 of 6471 2004 Tahoe Z71 Information

If anyone is interested,
The microphone for the OnStar system is located on your rear view mirror.
The Transfer Case will only take Auto Trac II. This is only sold by a Chevy dealer. I asked the dealer several times if it was the same type of fluid as Dexron III, Gear Oil, or was it a special weighted fluid? I was again advised that you could not put anything else besides Auto Trac II into your Tahoe’s Transfer Case. This is not to good for us that like to shop around and get the best prices, etc.
Just a reminder for those of you who did not see my post on the spark plugs. Don't wait until you have 100,000 miles to change them. I had 51,300 when I pulled mine and changed them out. They were all very brown. The dealer uses Delco Plugs. I bought some E3 plugs that work a lot better and are less expensive than the Delco Plugs.

Newsflash: brown spark plugs (insulator) are indicative of an engine that is running with the correct fuel/air ratio.
What are you basing your statement on that the E3 plugs work a lot better?
#6150 of 6471 95 2dr 4x4 Problem. Please Help!
Jan 20, 2007 (2:04 pm)
My 4x4 has worked for the most part since I bought it. It was working just lately, and as I drove it, the front axle light in front of the lever flickered and turned off. My lever was still engaged in 4hi. From noticing, my 4wd doesn't work anymore. I can shift it into 4hi or 4low, but my front axle light will not illuminate. Even when I pull forward a little or backward. And I've tried driving around a little and then shifting it in and it still doesn't work. What do I need to replace? (I've already checked the fuse)

I tried and can't even get my hand down far enough to reach the area you suggested. Thanks for the info. I'll see if I can find someone who can do it for me.
Did you ever find out what the problem was with your Tahoe not starting?
