    What is the difference between a 1500 HD and a 2500?

    JOHN...Your truck may need a PCM reflash. My 01
    did the out of gear bump once in a while.
    A PCM refash fixed it...........

    I have read about this on this forum before........
  • Thanks for the info. Now Ijust have to find out what aPCM flash is?????

    Check to see if GM has a TSB on this issue - I know they did for the 1999 Silverado. I live in Houston and it does not get cold enough to cause the problem - but while in Colorado on a ski trip I had the door rattle problem. Months later I saw the TSB - but never bothered with getting it done.
  • geo9geo9 Posts: 739
    I am sure one of the guys will come up with the TSB # for ya. Like I posted it has been mentioned before.

    My 01 is gone now and don't have the paperwork........
  • Mine did the came thing so I took the door panel off and used a entire roll of two sided sticky foam padded tape on the inside of the door. Before I took it apart I tapped on it to see where the rattles and noise was coming from.
    so far this $3.00 fix has worked great.
  • Same problem with my 2004 Silverado but was all covered under warranty. Dealer said they have been having a problem with the fuel lines rusting on the inside and plugging up the injectors. They changed my fuel lines and injectors and everything is fine now.
  • I don't suppose you know where I could find that TSB? Do you know what the fix is for the windshield noise?
  • MY 1993 4X4 AUTO TRANS WILL SHIFT INTO REV, 1,2 BUT NOT 3 OR 4. I AM TOLD THIS IS A SAFETY FEATURE THAT ALLOWS YOU TO LIMP IT HOME. HOW DO I FIX THIS PROBLEM? :cry:

    This kind of sounds like what has happened to my 95 K3500 a couple of times. It's like the trans is stuck in 2nd gear. All I did was to disconnect the battery for 10 minutes or so, which clears the code out of the computer. Reconnect the battery & that cleared the problem. Not sure if this will fix your problem but it's an easy thing to try.
  • steve80,
    Do you know if there is a recall on this? Can you provide the dealership name that you went to so I can call and ask them about it? thanks, jason
  • I have not experienced this with a chevy but I had a similar problem on a Dodge with my ignition coil loosing contact at the plug. My truck would stall and start right back up, and it would also loose rpm at idle sometimes, but I never had the mushy brakes.

  • 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
  • got the truck last night. me and to buds put a new cab on it. had to use old wiring harness and dash. everything works except the fuel injector. engine runs with starting fluid. but no feulto injectors. any suggestions??????? :cry:
  • 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?

    thanks,

  • Jason,
    I`ll check with the dealer and get back to you .

    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.
  • 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.
  • Jason,
    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.

    I am in the wrong forum I think, but I'll try anyway. I'm Considering buying an '03 2500HD w/8.1 engine. I don't tow anything, but love the beefy look of the truck and the thought of the big motor. Am I stupid to buy an 8.1 for daily driving? I may get a boat in the near future, but that's it. I'm not real concerned about the MPG. If any of you have an 8.1, have you had any problems with the motor? I think the one I'm looking at is a Vortec.

    I, TOO, HAVE HAD THIS PROBLEM. STARTED WITH SPEEDO. THEY "REPAIRED" THE CLUSTER FOR $500+ AND NOW THE OIL PRESSURE AND FUEL GAUGES ARE READING HIGH. JUST TOOK IT BACK AND THEY REPLACED THE "CLUSTER" AGAIN AND IT HAS NOT CHANGED THE PROBLEM! DEALER TECH TELLS ME HE "CAN'T HELP ME".. THIS IN A 2003 WITH 109K MILES. CHEVY TECHS DON'T SEEM TO UNDERSTAND ELECTRONICS! ANYBODY HAD THIS PROBLEM AND GOTTEN IT SOLVED?
  • I don't have an answer but I do share your frustration. I bought a very gently used (32,000 miles) 2001 2500 HD Duramax with the Allison transmission, to help out a friend. It was like a car/truck for me, nice soft ride, quiet engine, strong enough to pull a trailer or haul a load of grain if I had to but not for heavy work. I did not work it hard, put on some highway miles and took care of it.
    In the past two weeks at about 54,000 miles I have put about $4,000 into the truck, and also had all the injectors replaced under warranty. The transmission valve repair came to $2100, and that is after the manifold gaskets failed.

    Just wrote a $44,000 check for a new Ford. It's my fourth Power Stroke, and I still haven't had to replace injectors even at 150,000 miles. I'm pretty down on Chevy right now.
    Duramax is handling the injector problem but Allison is not showing any interest in backing up their transmission. I've got a Top Kick and an International deuce-and-a-half, both with Allisons, and have had no problems, but this Chevy Allison sucks. :mad:
  • go to autozone and have them check for codes in the ebcm. Its probably code co265 If it is check the ground right under the driver door clean the undercoating off and remove the star washer off the ground strap. If that doesnt fix it then its going to need an EBCM. Its about 900 dollars takes 5 minutes to install and have to have a tech 2 to reprogram the tire size after instalation

    You're in the right place dschro. I have an 02 with 75K+ miles. Just finished its first tune-up. If you like the sensation of lots of power under your right foot and MPG is not an issue, then you'll love the 8.1L. Just make sure it isn't a victim of CSK as mine is; If it doesn't knock when first started after sitting overnight you should be fine. That would be the engine choice if I were replacing my truck today with a Chevy or GMC.

    I've been in vehicles with the noise you describe and it's always U-Joints. They seem to be the weakest link in the design, (but the easiest to fix). And the fact that you have a 6" lift makes them even more suspect; The greater the angle, the greater the stress. If you take the cap off a U-Joint and find longitudinal ridges on the inner race, that's what's producing the humming.

    freekydogg: If you can get a hold of a fuel pressure gauge and hook it up to the fitting on the fuel rail, it may help to diagnose the problem; With the key in the 'on' position, you should have 55-60 psi.

  • Just bought a new 2006 Silverado and you guys are scaring me. Is there anybody reading these posts who hasn't had problems with their Silverado? I did own a Chevy truck many moons ago and it wasn't all that good of a truck. I'm really not that much of a brand whore but I have a long memory. Chevy's are reasonably priced and we got a good deal. Thanks very much. Johnny
