Please note the sizes. Download speeds should be good. On my 10Mbps cable, I was getting full 1.2MB/sec download speed.

Here are additional individual manuals that were previously available on another site. The site has since gone offline but I saved all of these manuals, which are now available here. From what I can tell, these are separate sections from the main large manual above.

Thanks for sharing!

DL now, what manual is this?

it looks extremely extensive... is this the GM service manual?

I got a warning saying I needed to register this or the other.


My pleasure. It was someone at TV that shared them and I just made it easier by hosting them since file sharing sites are crap. And since I don't really use my site for anything (really, there's nothing there so don't even bother), figured it could be put to good use. They seem to be some sort of factory manuals or third party but they're legit. Only thing I could see in there was "Courtesy of General Motors". Thanks GM!

Nothing to register. You should just get a prompt for the login and password. If any problems, just send me a PM.

PS: I don't know why, the links at the OS don't work anymore :tongue:
:goodpost: This will be a handy resource for nooblets as well as veterans who didn't get em the last time around. :biggrin:
Oh sweet *downloading*

have multipal copys of each, one of each lap top, and one on my pc. Thanks!
Why not just use dropbox so you can easily access it from any place?
If anyone is having speed issues to download the TB 02-05 Manuals (since it is 870MB), you can use JDownloader to get it. I was using chrome to download it and the first 10-15 sec I would get about 2.0MB/s then it would throttle down to about 25Kb/s and then get stuck and stop downloading. Not sure why, I tired it with IE as well and got the same problem.

When I used JDownloader it took a while but I got the whole file. Thanks again OP! :smile:

You don't need to specifically use JDownloader, I would assume any kind of download helper would work, I just prefer JDownloader.
Can these be posted on a resources section of GMTNation? I am not too keen about downloading from a private site and the other link provided in another thread is routed through a tracking website.


Umm this is a privately owned site... What would be the difference? One of our members has posted it and hosting it, you only have to download it once. IMHO

I have 45Mbps fibre at work.
These came in at the full 4.5MB/sec. Loving it!
Great post!

As you saw, these are pretty hefty and could be troublesome for the forum to host and hard on its bandwidth. I own the site and primarily use it for email since the site is basically just a shell, never having the time to actually build it. It's an unlimited storage and bandwidth account. So far, with all these downloads, my webhost has not said anything so I assume it does not bother them. It's just a normal HTTP download with a login and password to prevent anybody else from just posting a direct link and I don't collect any info. I don't know what other thread or download you're talking about but if it's the ones on the OS, then I can't say anything about those but I recommend downloading them from here. Nothing to do with not liking the OS or anything, you have nothing to worry about here :thumbsup:

I download the 02 file, but buggered if I can open them. I used Winzip, then Adobe 9.4 and it says that it is unsupported or damaged. Any ideas? Maybe my Adobe is too old...but so is this PC, so I can't upgrade to the new version yet.

I downloaded the file and no problem here. I just used the native Windows 7 ZIP functionality to extract it and opened each PDF, no issues. I also used WinRAR to test the archive and it found no errors. Maybe try the following:
- Use WinRAR to extract the ZIP file
- Re-download it. It could have been corrupted during the download. It happens.
- Maybe try another PDF viewer.

How old are we talking about here? If it runs WinXP, it should be able to run Adobe PDF viewer.

Older than's a step up from a stone and chisel! :rotfl:

I'll play around with it and see what I can do.

Hey Moose thanks a bunch for making this available, I do all my own work on my TB and this sure makes alot of stuff much less time consuming.
For most of them, they list TrailBlazer, Envoy and Bravada. For pretty much anything mechanical, they would work for all GMT360/370 (TrailBlazer, Envoy, 9-7x, Bravada, Rainier, XUV, & Ascender) as they are interchangeable. One thing that was listed only for the TB was the wiring. Maybe another thing that could be a bit different is interior trim and exterior lighting. Even then, some of these would still work. Wiring would be the same for everything except the lights and instrument panel.
