duramax

  1. Exterior
    My Duramax started to whine yesterday on my way home. I have a loss of power and the whine increases with my rpms. Any advice or help on what the problem could be? I am concerned its my turbo. I have a video showing the sound but I can't seem to attach it to the post.
  2. Transmission Shop
    I’ve been looking for a good core to rebuild to just swap into my truck and this guy a couple hours away from me claims he has an Allison 1000 6 speed from an 06 classic with only 130000 km on it. I’m not to good with identifying serial numbers or dates but here’s the picture of the tag. Any...

    Having a really sporadic and wild issue with my Duramax as of recently. The truck has 204k with pretty great maintenance. This issue has been pretty intermittent over the last 2500 miles or so. Below is a video of what is going on, this instance is about the worst it gets but when towing it is...
  4. Transmission Shop
    So I recently cracked the bell housing to my transmission and it lost all the oil. I’ve been looking around at good used transmissions (used because it is my work truck) and I’ve been told the plugs and other things change from year to year. I have an 06 LBZ with the Allison 1000 six speed. Am I...

  7. 01-04.5 LB7 Performance Parts Discussion
    Ok so it’s an old truck but it’s got 50k miles on it and it’s clean as hell. Like probably the cleanest I’ve had and that’s saying something. I’ve done a few small things but nothing like what I’ve done to my others. It’s a 2003, I’m gonna do my best to not go crazy with it but.......it’s hard...
  8. 01-04.5 LB7 Duramax Powertrain
    Hey all! I hope this is the correct place to post this but I’m having more issues with the truck. Got the transmission rebuilt and all was good for a few months until I crack the extension housing. Got it back from the shop over the winter and everything was good and back to normal except a tad...

Here’s what I know is done to it from a performance stand point: almost everything on replaced but too much to list Brand new 6.6 Jasper Duramax Motor (ARP studs) -Upgraded Crank Shaft -Built...
  10. General Discussion
    After 17 years and about 230k it’s looking like time for new fuel lines on my LLY (crew cab short box). Not seeing a lot of straight forward plug and play kits online. Lines to go.com has a few however I don’t see many reviews on their kits. Does anyone have any recommendations on fuel line kits...
  11. Maintenance
    So I have got a 08 Duramax and was pulling in to my house one day and the drivers rear brake completely locked up after I was on the brake. I put the rear end on jacks and cant spin the tire. So i replace the caliper, take it out on a test drive and still does it. Lift it up again and can spin...

  13. 911 Problems Forum
    I was working on our lly duramax today. I’m having issues with a rough idle among other things. It idles like crap and doesn’t rev past 1500. It has a little blue smoke, I pulled the plug on the ignition switch to try to figure out a range shift inhibited code, and it started to run fine, but it...
  14. 01-04.5 LB7 Duramax Powertrain
    Hello fellow dmax owners. I recently bought a 2002 Lb7 duramax with the zf6 transmission in it. While tearing into the motor I noticed that majority of the push rods were bent. I checked the cam gear pin and the crank and they are both in good shape. Could the valvetrain failing cause all the...

    Howdy, everyone. I'm really in a bind with a current electrical issue I am having and I need to try to fix it before the weekend when I tow my fifth wheel out of town. My truck has been making a clicking sound when I press the brake pedal (like a relay switch type of click, very audible) and...

    Good Afternoon, I hope you are all doing well. My stock emissions-intact 15.0 LML has been tucked in storage for a few years due to a significant winter advisory and the truck has been there ever since to save money. I have been pondering the aforementioned idea to begin daily driving the solid...
