Howdy gang. Just did a search on TSBs on here and didnt really find what I was looking for.

 

Where do I find TSBs for our trucks? I have a squeel coming from my '06 8100 and have read on here that their is a TSB on that.

 

I want to see what all is out there in case I have furthur issues with the truck. The squeel is driving me nuts and want to get it taken care of.

 

If a truck is still under warranty and I show them the TSB on the idler, will they fix it?

 

Thanks guys/girls.

 

Go Patriots!

Alldata is one provider of TSBs, but its a for-pay service. For safety recalls you can find them at the website for National Highway Traffic Safety Administration. Not sure where you can find complete TSBs, for free. Many of them that I have seen are just headlines and then you have to pay for the body of the TSB.

 

If you wave a TSB at a dealer along with your complaint, I suspect the odds are better it'll get fixed. Just like the dealer, a private individual can misdiagnose a problem and think a particular TSB matches the symptons when, in fact, it is a different problem.

Hey cheekster, you might want to check into the pully wheel on the alternator, I think. I have the 6l in my '05 2500 HD and it squealed like a pig. I took it in a few times and fought with my dealer a few times over it. Then I read up on it and found out that GM outsourced their Alternators to some Asian Co. (surprise) with less than stellar QC. Supposedly they fastened the pulley to the Alt. by some cheap-ass method and the flange gets sloppy on it, therefore creating the squealing. There is a TSB on that also as the tech finally found it and repaired it without a problem since. And yes it is VERY nerveracking.

Don't quote me on any of this as I am not a motorhead and it happened over a year ago, but the general problem is correct. I am almost certain it was the Alt pulley, but could have been something else. I know for sure that they changed out my idler wheel once and that definetely was not the problem. Let us know what you come up with.

I squirted the idler with some WD-40 on the front and rear of it and the squeel went away, only to come back the next morning. So, it isnt coming from the alternator pulley, belt is new (5500 miles on truck). I get some time off next week, I will swing by the dealership and see what I can get done.

 

Thanks all.

 

Later

Just FYI, the dealer changed my serpentine belt also and the squeal went away for a little bit and then came back about 2 months later and after taking it back to the dealer(50mi rd trip) and getting quite agitated over them not being able to find the problem, they finally discovered the TSB on the pulley. I also did all the WD-40 tricks and the belt dressing sprays and what-not and they all helped temporarily, but in the end that bad crimp on the pulley wheel was the only thing that stopped it. Now maybe this will help and maybe it won't. I cannot be certain we have the same problem, but at least have them check into it. Just trying to save you a few trips back and forth that cost me some fuel $$.

 

Let me tell you that mine actually started out as more of a "chirp-chirp-chirp" sound at idle and not a full blown squeal. It ended up getting gradually worse and was very noticeable when driving, obviuosly from the higher RPM's. I guess all the chirps ran together to make a squeal. I really noticed it when it got warmer and my windows were down and I could hear it echoeing off buildings and parked cars. I didn't notice it when it was cold out because my windows were up/radio on, but my co-workers mentioned it to me a few times. As I said before, keep us posted on how you make out.

I have exactly the same issue on my '01 8.1L. Had the idler replaced about 2 yrs ago and the squeal went away for about a month. Lived with it untii it got really bad and went to the dealer, they said the belt was bad and replaced it, lasted about a month and the squeak was back.

 

What's the fix on the alternator pulley? New alternator?

Burbman, I think they have a"fix" for your pulley. As I stated earleir, I am not 100% sure it was the alt, but it was definetely a bad pulley. It was described to me that since it was outsourced to a foriegn supplier they put a "flare" in the metal to hold the pulley on instead of a nut or keyway and it gradually weakens and creates the squeal. I thought I posted on here about it when it happened. I will have to do a search and see if i can find it from when it was all fresh in my mind.

Howdy gang. Here is an update to the TSBs.

 

I havent found a specific TSB for the squeeky pulley on the 8100 motors. I spent about an hour today at the NHTSA site looking up various TSBs. Unfortunately, there are not alot offered for 2006. There were over 248 available for the 2005 models.

 

The two that I found are:

1. Service bulletin # 3436. Accessory drive belt noise on cold starts. Reposition power steering pump pulley. This one does not specify which motor.

 

2. Service bulletin # 0509610018. Accessory drive belt chirp, squeal or squeak type noise at cold idle.

 

Gonna take my truck in next week and see if I can make that squeak go away,.

Cheekster, any luck? I had mine in last week and they couldn't find the bulletins you reference above.

Burbman, havent taken it in yet. Plan on tomorrow to discuss the pulley/idler squeek and my passenger rearview mirror crack.

 

I got those two TSBs from the NHTSA website. I only looked at 2005-2006 model years. I would assume the furthur back you go in years, the more luck you will find with TSBs.

 

I ll keep all posted what happens tomorrow.

 

Later all

You can subscribe to AlldataDIY.com for your specific vehicle to get access to the TSBs and other repair info for about $25 per year or $45 for three years.

 

The only issue I have with AlldataDIY is that it takes them some time, 3 to 6 months or more, to update the vehicle specific TSBs. However, they indicated that you can email them and they will check to see if any TSBs have been received, but not yet posted to their DIY site.

 

I subscribed for 3 years for both my GMC trucks. The average cost of $12.50 per year per vehicle seems reasonable to me to avoid dependency on my local stealer.

My insurance company (Progressive) gives me TSB access via a relationship with Edmunds. You can always check your insurance company's website to see what features your premiums are paying for.

      primary drive belt tensioner

      I bought belts and pulleys for my '20 L5P at Rock Auto a couple years ago. I have used them for many years, and almost always save significant money, especially when I buy maintenance stuff ahead of time.   They carry many OEM parts, which is all I use unless an aftermarket is shown to be same/superior, or if it is an insignificant part or unavailable OEM part anywhere else. RA is usually lower priced, often by a bunch, but parts are sometimes unavailable or out of stock, and I do shop around and sometimes find better prices at other sites.   Be aware that you pay shipping, and if you buy multiple items and they are coming from different warehouses, the shipping can kill the advantage. Planning ahead is best if possible.   If you have a transmission service in the near future, check out their OEM (AC Delco ULV) fluid, usually MUCH less than anywhere else.

      10L1000 anyone with High Mileage ? I hate Damocles....

      By Deadwood · Posted

      New member here, very long time occasional guest. Saw this thread, thought it would be a good time to contribute someting. It is only my experience and not a claim that everyone will have the same.   I bought my '20 3500 L5P new and have put 99.9% (literally) of it's current ~400k miles on it myself, with over 50% of that towing loads between 4k to 15k, and to me this truck has been nothing short of amazing. For the first 235k I had zero issues, and from there until 321k I replaced a NOx sensor, two failing glow plugs, and three of the notorious injector connectors. I believe this truck is in part, a testament to good luck, but also good care and following a decent maintenance schedule (I also keep meticulous records.) As a result, it looks as good as a well cared for 70k rig, up and down, inside and out.   At some point before that 321k mile mark I began to get a little spooked about the 10L1000, especially the valve body. Word of mouth about potential issues prompted me to jump on the net to sift through all the noise and determine what all the fuss was about. I routinely take long trips, coast-to-coast and points in between, so roadside breakdowns can be '...a thousand miles from nowhere' and a bit of a challenge, and though I had no issues, my guard was up and activated.   And then I stumbled across a chance to salvage some parts off a new 2025 that had been wrecked in transport. I grabbed a few wear items (alternator, pulleys, etc.) and on a whim asked what the ten speeder would cost me. It was cheap...really cheap. I knew some changes had been made in the '24+ version 10L and were supposedly not compatible, but I called service/parts at my local Chevy dealer and asked why and they didn't know. A call to a well known aftermarket transmission outfit revealed it was very likely it would be fine, but to them not 100% sure.   Because it was cheap (really cheap) and I was spooked, I took the chance. Had it installed by a local shop and it worked like a champ, shifted just like the original. At it's first service at 37k, I had the shop put in a Next Gen valve body kit, which after some initial hiccups and rough shifts, smoothed out though with somewhat firmer shifting.   All that said, I have a very serious concern about my newer transmission as just two weeks ago it suddenly began to exhibit a strong reluctance to engage forward or reverse. It was a bit past due anyway so I took it in for service. The reason it was sticking was due to 'glitter' in the fluid clogging the filter...not good folks, often indicates a converter giving out. We ended up going ahead with the new filter and fluid, first to see if it would move and shift, and then if so buy me a little time. It did, and I've driven it over a thousand miles and it is shifting smooth, no noises or slipping. Regardless, it looks like a third gearbox is in my future so I can resume taking long trips with some confidence. In the very short term, my curiosity will have me examining the fluid to check how much glitter has reappeared.   An earlier poster had alleged, in the context of 10L100 failures, that it is another example of how we seasoned citizens somehow descend into hysteria, lose control of our senses, and react irrationally after brief encounters with the idiocy of the internet infosphere. Let me say (and I have used and abused said internet since it's infancy) there is no segment of the populace that has a corner on over-reaction to digital garbage. Just as my offering of experience in this arena is purely anecdotal and should not be considered gospel or all-encompassing, I believe it is still worthwhile information to consider, along with other relevant anecdotal experiences about things like complex transmissions, especially when balanced with other sources.   So to answer the original question, yes I got high miles out of my first 10L, trouble free for 321,000. Now I really wonder how much longer it would have went. Did I 'overreact' to the internet ghouls by replacing a 'good' one with a 'bad' one? Maybe. Who knows, the thing might have taken a puke a 100 miles later. So I'll just fix it again, then move on and start thinking about all the other stuff that will eventually wear out. It still has the original brakes (they're at ~60%), original injectors/pump, turbo, water pump, etc....pretty much original everything. Knock on wood.

      6 Speed vs 8 Speed

      At peak temperature.  They get to cool down and warm up more, especially those with the external cooler.  I have three GMT900s and one of them has over 225K on its original transmission.  Fluid gets changed about every 36K miles, all of it.     It's not the bean counters, it was the government.  They had to meet CAFE standards and other government requirements.   To get around that, we tune them and modify them to our liking.
