You probably have an answer to this, but I own a 2000 1500 w/5.3. All I do when I change the filter is to loosen the fittings and let the pressure bleed off, then R & R the filter.

Dave,
   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 ?

abs light by leggett
Sep 28, 2005 (9:30 pm)
99 GMC Sierra- On initial start up, I get a red brake light and ABS light on instrument panel. Brakes appear to be working normally and can reset the lights by cycling the ignition switch w/ engine running. The dealer offered to repair for 1,000 dols- i declined and was able to determine the fault code from the scan tool was 0265 -"EBCM relay circuit open." Does this really require the replacement of the entire electro-hydraulic control unit- since i have found i cant just replace the EBCM? Or is there another fix i can attempt since it's a "relay circuit open"? What kind of job is it to replace the EHCU if i have to go that route? T

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.

fuel filter by jlopez
Sep 30, 2005 (9:57 pm)
How do I replace the fuel filter in my 2001 GMC Sierra Z71 pickup with a 5.3 liter engine. I can't seem to find where the fuel filter is and I am wondering what tools I will need. The owner's manuel has not mention as to where the fuel filter is and how to change it.

the fuel filter is right under the drivers side door. it is tucked up inside the frame. all you need for tools is a 15mm or 17mm wrench i think its been a month or so since i changed mine. its easier to see if you look from the passenger side first under the door and look across to the drivers side. its in the frame. good luck

2002 GMC DuraMax w/ Allison by gmboy1

Problem:
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.

David,
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

Thats a nasty little deal right there. I would check the wiring harness that comes up the steering column for a short between the two circuits or between the starter wire and the shift linkage. I've had vehicles in the past with tilt steering that would get a wiring problem. Usually they were high mileage vehicles that did that. I'm surprised to see an '02 with that problem. Hope this helps. If I had a manual I could tell you the color wires, but I ain't got one. Sorry.
 Good luck - let us know what it turns out to be OK?

Bob;
      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.
