  1. Duramax Second Generation: 2004.5-2005 (LLY)
    It seems that a lot of ‘04.5-‘05 LLY Duramax trucks are having similar problems with the glow plug controller, so I wanted to post the problem and the solution for others who may be going through the frustration that I had to go through. Last summer, I was towing my camp trailer home with my...
  2. Duramax Third Generation: 2006-2007.5 (LBZ & LLY)
    New guy here lol. But working on an LLY and replacing FPR. How tight should screws be when I install it? I put the 3 new allen head screws in that came with the FPR. Forget the torx screws lol. I know what the torque spec is in lbs-inch but i cant get my 1/4" torque wrench in and just want a...
  3. Duramax Second Generation: 2004.5-2005 (LLY)
    So I’m pretty sure my ecm is fried, what are the best ways to go about getting my truck back up and running or is it a lost cause, definitely little worried!
  4. Introductions & New Trucks
    Hi, I'm Jesse, new to Diesels, just picked an 05 lly Duramax 4x4. I'm excited to play with this a little. I have owned many Tundras. All of them lifted, 1 of them supercharged. My Duramax is a shortbed extended cab. The 6" lift got here today, and a set of 20×12 fuel wheels with 35s as well...
  5. Allison Aftermarket
    I'm about at my whits end with my built trans. Had it built in March of 2022 and ever since I've been chasing a leak from the bellhousing area. Shop that built it had been great about trying to fix it under the warranty but it still leaks. They resealed the whole trans the last time they had the...
  6. Duramax Second Generation: 2004.5-2005 (LLY)
    I have a 2005 Chevey 2500 4x4 lly. With 320k I have an rpm jump when in idle about every 10 sec. Guessing that’s the fpr. Haven’t fixed that yet. Something new that has been happening is sometimes when I amon the interstate I can’t go over 65 mph. Then when I accelerate it lurges like the turbo...
  7. Duramax Second Generation: 2004.5-2005 (LLY)
    new to this form and duramax’s lol but i recently bought one in tractor mode and have been going through all the ice picking and replacing pig tails and checking the ficm bracket by the alternator and a couple other spots i’ve seen through these forums but the weird part about it is i have no...
  8. Who sells [fill in the blank]?
    My remote is getting pretty worn out and is probably 1-2 hard-floor drops from being done. Where can I get a replacement? Maybe just the outer case replacement even. For a 2005 LLY if that matters.
  9. Wheels & Tires
    What is the max tire size that will fit on a 2005 leveled 3/4 ton? Just trying to get my truck to look tougher. Thanks guys
  10. Duramax Second Generation: 2004.5-2005 (LLY)
    Short story version: Truck sat for two weeks while I waited on parts and time to swap out steering gearbox, pitman arm, and tie rods. That all went fine. Went to take it to the shop today and it stalled out, found that it lost prime. Got it running again and got another 2-3 miles before it...

  12. Allison OEM
    I’ve dug through the forums I can’t find anyone that is or has had the same symptoms. My truck will pull a trans code of u0100 lost communication with ecm/pcm “a” when I start it up. Then as I drive it will throw more codes. I have checked wires checked connectors. I have read it could be a nsbu...

    Hey guys i have a 05 duramax after the truck warms up it clings when you shift from park to reverse, reverse to drive. Also it makes a noise almost like a baseball card in a bike tire in first and 2nd only especially when downshifting 3rd on makes no noise. I parked it one day got back in it and...
  14. Duramax Second Generation: 2004.5-2005 (LLY)
    So I learned the hard way on the road that my LLY runs hot when towing in the heat. I already have a k&n intake that I’m not wild about (plan was to upgrade it to a different filter). Can I run an improved turbo mouthpiece with the K&N intake or would I need to swap that out to make it work?
  15. Duramax Second Generation: 2004.5-2005 (LLY)

  16. Duramax Second Generation: 2004.5-2005 (LLY)
    So long story short I bought an 05 2500 with a screwed motor and bought an 04.5 LLY that was out of a C5500, swapped all necessary items and opted to stick with the 2500s injectors (new reman), wiring harness and other modules to ensure there wouldn’t be any issues. Now trying to get it to fire...
