Any One Have Factory Gm Info Access?

[comp]

THOUGHT i'd do this post to help all of us when we need to contact somone with a specialty, mine is JACK OF ALL MASTER OF NUN!
jump in it can be like a directory

[-Josh-]

i can help out in that area, i have the ability to get all kinds of GM access info about....well just about anything technical.

[comp]

thats one in the mix,

[Hypsi87]

I know a little about turbo buicks, and if I don't know it I have plenty of books that do

[comp]

allright #2 i'll be getting ahold of you about a turbo idea after
i do a little more homework, i'll probably kill my own idea with a little more studying

Does anybody know what a code P1811 in a 2000 Buick Century means

[comp]

i don't have but someone will may take a while for all to check in

[-Josh-]

I'll get back with you on that one in a few hours, going to see the movie butterfly affect...

Apparently, after doing some research... I learned that in the model years 1999-2000 some of the 3.4, 3.5, and 3.8 ltre engines had erractic shifting, and this would set one of two codes a P0748 or a P1811. Problems that could be causing this are:

1.Sediment inside the pressure control solenoid (PCS), causing a binding in the PCS valve.

2.Sediment in the valve body, causing the torque signal regulator valve to stick.

3.Incorrect transaxle oil level.

Any of these conditions affects line pressure in the transmission. So that's your most probable cause.

I just registered after seeing what goes on here, nice site!
The main reason I visited was to see what was being said about "our" product, which is the 3800 V6 {naturally aspirated & supercharged} that we build at Flint's V-6 Engine Plant, but will always be known to me as "The Buick" as that's what it was called when I hired in.

I've been a departmental quality chairperson for over ten years now and have been involved in building engines on the line and troubleshooting quality issues, which can sometimes get interesting.

To be honest, I could'nt fix one if my life depended on it, except in our repair bay, just know how to build them and in the factory we have all the "goodies" to make that happen in the easiest manner possible with many tools made up by our skilled trades.
Our current line speed is 190 engines per hour.

Any production related questions and I may be able to help but I think that I'll have to watch myself as I have access to what's called GM Confidential information, which we are not to share.

I get around the whole factory and have to work closely with the case, crank & front cover departments to resolve issues that deal with these three components. In our dept, we install the front cover dowel pins, rear seal carrier plate, rear lip seal, front cover w/water pump, flywheel, crank sensor, oil pressure switch, rear dowel pins {trans}, stone shield {crank sensor shield}, hamonic balancer / dampolater, oil suction pipe, oil pan, oil level sensor & oil filter in that order.

After these parts are installed, we run the engine through our Short Block Leak Test where the oil cavity is then checked for leaks using air, which has to maintain a certain cc leak rate for a specified time period to pass. The parameters for this leak test differ for the two different oil pans we install, one a stamped metal {black pan} & the other cast, which is made of "white metal" and is called a structural oil pan.
Our Short Block Leak Test, has, and continues to find, defects that the "naked eye" never could even if you knew they were there.
Today it caught over 10 cases with defective mills at the front cover face, some days things go great and we find nothing, but that all depends on the parts we receive from our machine floor.
One of the defective cases found today was barely out of spec., and I mean barely, when it was Ziessed after "tear-down."

Later!

Now that's a guy who can be helpful, what's better than getting info from GM itself.

[comp]

yep thats why i started this one, i hoped we can get several with access
so just a few aren't over-loaded and burnout

[Flatrater]

I'm a GM dealer tech if you guys haven't noticed! I have acess to the service manuals from 1998 and up and service bulentins from 1980 to present..

You can usually see me here everyday as time permits.

I know how that is I work at caterpillar's proving grounds. alot of CAT confendential stuff going on there.

Comp, I want to thank you for posting this thread. It really got me to thinking about everything I've learned while working at "The Buick" for almost 30 years.

Back when we were "rolling out" the Series II & OBD II changes I was one of two selected to represent our department, not because I'm highly educated, because I'm not, but for my practical knowledge about our engines and the manufacturing concerns that engineers all to often leave out of the equasion. Sure it looks good on paper, but can you build over 1,000 of them in a 8 hour shift? The engineers never used to think about this, but all that has changed and we're consulted far more often than we used to be.
Your thread now has me thinking more about the engines we build instead of just going to work & taking care of business on a day to day basis.
Today, because of this, I decided to dig through the mountian of "stuff" that I've saved from the trash at work and found something very interesting that I even forgot that I had. It's a publication put out by Buick Motor Division explaining, in detail, how to build our engines.
When I say build our engines, I mean BUILD THEM!
It was printed in 1985, so is somewhat dated, but it shows in great detail how to build V-6's for the following applications:
USAC Turbocharged Indy
Trans Am Racing
Normally Aspirated Drag Racing
Turbocharged Drag Racing
Turbocharged Road Racing and Normally Aspirated Circle Track

It even mentions how to build a V-12 out of two V-6's!

Some of these engines are rated for over 700 hp!!

I also came across a Factory Build Book from the 80's, which was given to me by an engineer, dealing specifically with Turbo's and the interchangeability of parts between the 3.8 & 3.0, something I didn't know. Please keep in mind that Factory Build Books, of which I have over 20 years worth right up through 2004, are geared to our use and we already know how to put them together. We use them more as a quick reference when running a code that "the other shift" usually runs so we may need to look up what parts are required for that specific engine code. They are basically diagrams showing how the parts relate to each other with part numbers and are listed by departments so may not be of much help to the fellow working at "Joe's Garage."

Thanks once again for sparking my interest........................

Jack
