#998 of 1497 Humming Noise at 65mph
Jan 08, 2006 (5:57 pm)
I have a 2004 chevy silverado 1500 crew and whenever I am driving between 65-70mph I get a loud humming noise and vibrating noise. Its not a high pitched noise it more like a roaring humming noise. I have 45,000 miles on the truck and it just starting doing this at about 43,000 miles. It sounds like it might be the rear end or the transmission, but I don't know. I also have a 6" lift kit and 33" tires on the truck so that might be causing some additional stress. If anyone knows anything please let me know. Thanks

#1000 of 1497 2000 1500LS tranny slipping
Jan 08, 2006 (10:02 pm)
the tranny on my 2000 5.3L 1500LS seems like it's slipping or stuttering when it should be down shifting, like when I'm going up a hill. It's not making any wierd noises, it just stutters until I bring up the rpms and it downshifts. The tranny works great any other time. Any ideas on things to check?

Go to Carquest and get a roll of thin black double sided tape. Clean under the rubber strips on both sides of the windshield. Install the double sided tape on the underside of the rubber strip and press it down on the windshield.
The TSB may say to use silicone, but the double sided tape works just as good and is easier to remove if you ever need a new windshield installed.

I'm trying to get Chevy to pay to replace my inst cluster. GM customer service and my local Chevy service manager tell me its the only Silverado they've heard of with this problem. Started when it was still under warranty but it would only do it sometimes and not when I had it in the shop, so they wouldn't fix it then. Now tach is pegged on 6000+ and speedo reads low all the time. Dealer charged me $79 to tell me the speedo doesn't work! Wish I'd bought a Tundra!

I have an '03 1500 Ext 2wd in the shop now for speedo pegging. GM says $105.00 to open the dash up and verify speedo cluster is bad. I already know this!!! Truck will be tied up for 4 days because outside repair shop is backlogged. I originally opened the dash trim and fished a small wire between trip meter reset hole and cluster and moved speedo needle back to zero, but that did'nt last. Seems it only happened when it was wet outside. Thought maybe a loose wire harness to trans, but dealer says the cluster is bad.
#1005 of 1497 Over Heated? ATX when towing?
Jan 09, 2006 (5:59 pm)
OK I am new here so be kind, I am also a computer geek, not a mechanic so be extra kind!
First of all I made a mistake when I bought my truck and didn't get the 8 cyl engine, now for many reasons I am stuck with my 6 for at least another year.
When I bought the truck I had a trailer that was supposed to weigh 3900 Lbs, well within the 5100Lbs towing capacity of my truck. One day I weighed it and found it actually weighed 5600 Lbs with a regular load. I have since traded in that trailer and bought one that I have weighed at 4200 Lbs loaded.
Now, when I am towing long distance after about 1 hr I start to have problems maintaining 65 Mph, the towing Speed limit in Fl. If I get behind someone doing 60 and I pull out to pass and I give it too much gas, it down shifts, which I expect, but at 65-67 it sounds like the engine is going to come out of the hood at 4500RPM, I then let off the gas to get it to drop a gear after I have passed and it won't up shift, I have to take my foot all of the way off the gas and then at about 60 it will shift. Now I have lost all of my momentum and the guy I just passed is cursing me.
I also have this problem on over passes if I am around 65 and I give it a little gas to maintain speed.
I am not so worried about the down shift as I am about not being able to get it back in the regular gear.
Some have told me it is my transmission overheating and that a transmission cooler will solve the problem. Others have scared me and told me I have already cooked it.
It is still under War. 27,000 miles on it.
I know that this truck will never take me over a mountain but what can I do to help it in Florida.
Also I have noticed that I have a ton of power when it is cold and as soon as it heats up it seems to dog even without the trailer.
BTW I have a trip planned for this weekend so any thing I can do before then would be great!
Sorry for the long post, I hope all of the info helps
Thanks for any info you can get me.

Im assuming you replaced all the fluids and checked the engine to make sure it was getting compression. Then i would change the fuel filter and check the fuel pump. Should be pretty easy to figure out, but usually time consuming. Let us know how it goes.

Checked with the dealer yesterday and was told it was not a recall , but they were told to check for the fuel line problem by GM. Hope this helps.
