Where did you find the capacities for the trans, I looked all through my owners book and the supplement for the Diesel and did not find it. Just curious ?
Thanks,
Bob
You might be confusing the Owner's Manual with the Shop Manual. I bought the five volume Shop Manual when I bought my truck. In checking the Owner's Manual I couldn't find it there either. If you get hold of a S.M. it's in two places: Under "Maintenance and Lubrication", Page 0-39, and "Automatic Transmission - Allison", Page 7-676.
You sound like a kindred spirit on maintenance. But I have to confess falling down on the job lately (time). Still, I seldom ever go 4K between oil changes. Thanks for the info.

BTY- In case you're interested, here's the source for the Shop Manual for your truck. You sound like a prime candidate. Worth every penny.

When you put the truck in reverse while the car is running or not, the starter engages. Anyone aware of this problem or the solution? Maybe the neutral safety wiring @ the trans shift linkage? Any feedback would be helpful.
Thanks,
Bob
would have no problem purchasing it, could you give me the actual part numbers from the manuals. The site you sent me to does not explain whether ic contains all the diesel and Allison information, or do I need both of these:
2003 Chevrolet Silverado GMC Sierra and Denali Alternate Fuel Supplement
Price: $30.00 In Stock
(English, Paper, GMT03CK8AF)
Qty
2003 Chevrolet Silverado GMC Sierra And Sierra Denali Service Manual
Price: $135.00 In Stock
(English, Paper, GMT03CK8PU)
Thanks,
Bob
Good luck - let us know what it turns out to be OK?

The number on my book is, GMT/02-CK8PU-1 for a 2002 truck, looking very much like your second listing is the right choice. I don't think the Alternative Fuel Supplement has anything to do with diesel. My manuals have extensive material on diesel and Allison. Shipping took about a week to California. Good luck and let us know how it turns out.
-David
Since you had quite the same problem, did you find a solution or the cause of this problem.
Thank you!
It might be worth it to buy a Haynes manual to help you with diagnostic testing
so you don't waste money buying parts you don't really need.
No trouble codes eh?

I have replaced the battery and alternator, to no avail (I hate throwing parts at a problem).
Initially believed I had a bad hood light, so I disconnected it and then the truck would not start till I hooked it up again.
So I guess my question is, do I have a bad ground thats causing all these problems? And if so, how in the world do I find it?
thanks

Does your truck have the VYU plow prep. option?
If so GM has quick connect and ready to tap install connectors in all
of its full size pickups............
Go to http://www.gmupfitter.com publications-pg.27 for
full wiring schematics, pics. etc...................
NOTE: GM uses pos. ground on the power door locks ONLY !
The module is used for remote starter applications because of
this...........
Unless its a Western/Fisher plow........They use a module in the truckside
wiring circuit that controls the lights. It is also neg. ground.
They used to use a 6 fuse set up.
A aftermarket plow light brand should wire right in tho.................
Shoot me your e-mail.....I can direct you to someone who can help.
No I do not have the VYU option.
I had a 94 GMC and I wired after market plow lights to it. I had a toggle switch to switch from plow lights to truck lights. After I got my new truck I was talking with a plow dealer and he told me that if I don't have a plow light wiring module and if I tap into the lights that it will screw up the computer, day time running lights and the truck will not run correctly. Oh yes he has one and will sell it to me for a meer $350.00. I have a wiring diagram and I do not have a problem with tapping into the light wiring as long as I know that it will not mess up the truck.

P.S. Krylon 'Fusion' is available in multiple colors, I used black!
switch to operate the plow lights..................
I don't see why you couldn't wire the plow lights thru a seperate switch.
Check out http://www.letstalksnow.com/forums The plowguys over there
can help ya out......................
thanks for the help.
brake module. Did you check the brake light switch (on steering
column) and fuses?
Note there is a company that was posted around here that sells
remanufactured ABS units for a reasonable price. It was posted
on one of the 'Rado/GMC threads here..........Will look and post
when I find it.
The local dealership mechanics just scratch their heads and have yet to come up with any kind of solution.
Thanks for the reply. Foch.

Any info. will be greatly appreciated.
I hope this helps.
" Notice: When adding coolant, use Dex-Cool coolant. If silicated coolant is added to the system, premature engine, heater core, or radiator corrosion may result. In addition, the engine coolant will require change sooner - at 50,000 km (30,000 mi) or 24 months."
I can't tell you what is meant by "silicated". Regardless, I doubt if your facing imminent failure. Personally though, I wouldn't be comfortable with it.

I am also having them fix another strange problem with this truck.When truck was about 2 weeks old,I pulled into driveway and when I closed the door I heard something hit the ground.It looked like a louvered 4x10 plastic filter.I took it back to dealer and inquired what exactly fell off my truck.Supposedly this baffle,or whatever you want to call it stops your windows from shattering if you close the doors too quickly.They ordered a new one and supposedly changed it.Every time we had a good downpour here I would have water laying in back of cab on side where this "baffle" fell out.I don't think they ever replaced it because it,because accroding to the dealer the bed had to be removed.Anyway they are going to fix this problem as well.
I've also had the tailgate adjusted 3x's,finally getting it right after the third time.For the money,GMC is not the Professional Grade it claims to be.I've had trucks for almost 20 years and after this is fixed,I'm trading it in and buying either a Toyota or Nissan.I know people like to keep buying American,but I've finally had it.They are built like crap,and don't hold their value.Just look at the interior of a GMC and then go look at a rice burner,there is a big difference in quality.
After a little over 2 years with this truck,i've lost my confidence in it.The engine seems great 5.3,but the rest of the truck will fall apart around the engine. :lemon:
