    2003 duramax 2500 HD 4 wheel drive Strange noise

    I made a seal driver tool by taking the seal to the hardware store and buying a plastic bushing fro PVC pipe that fit over the seal. this gave me the internal clearance to not damage the rubber hump sticking out the back. If there is no vertical play in the front driveshaft yolk where it...

    Code readers for 2024 L5P

    See if EFI will pull the data stream on the LM2. I have an Ultimate and had to call banks b/c certain things were not working. I was told the L5P in select trims uses different communication protocols with the rest of the truck hence why I could not see certain things.

    2018 L5P Engine Miss

    If the electrical architecture is similar to the LLY's, when one injector experiences an issue, the controller shuts down the entire set connected to that controller. More than likely as mentioned one of the injector connectors is the issue. I did not Ice Pick mine on the LLY, but instead used...

    LBZ Fan Clutch

    What part of the shroud is missing? It sounds by your first post that the section behind the fan (LBZ encapsulated the fan in the shroud) making it almost impossible to change the belt was removed. Post pictures as this will help determine which portion is missing. I did remove the section...

    LBZ Fan Clutch

    The 2886 reached full lock a bit sooner than the stock fan and was I believe a bit stronger locking. One of the biggest issues is cooling stack plugging. You would be amazed at how much crap gets stuck between the stacks that you think you washed out. It's a bit of a pain, but pull the top of...

    LBZ Fan Clutch

    I ran the 2886 on one of my trucks. Good fan, temps stayed in check. I believe Adam (malibu) ran the 2886 on his hot shot rig for a long time before going spool in the summer. He had good results, but when he was having summer heating temps and the fan clutch would not come on fast enough...

    Trans flush or something else?

    I'm going to guess if the slave cylinder is getting toasted you may have more issues than needing just a flush. You might want to investigate the throw out bearing and the clutch. Bad throw out bearing can generate a lot of heat. Slipping clutch (even a little) is pure heat generation. Those...

    Need some guidance

    Since you can only open the cap when hot, fill it to that line and let it rip. There is an internal overflow that will purge any excess into a separate tank and draw back when it's cold. Make note of the level of fluid when hot and cold, and if it falls below those (after a few cycles of...

    Need some guidance

    As long as the coolant is returning to the same level when cold and you are not having to add fluid past possibly the first or second time you get it up to temps on the road for more than just long enough to get it to temp, all is fine. If it's one of the newer style coolant tanks with the left...

    Noise from Subwoofer

    Correct Ron. Trying to isolate the issue to power supply or if it's some how traveling through the RCA. I've picked up noise in the RCA on short runs just by it getting shifted too close to power wires (I believe there were some other issues in power feed also) and being looped. The way you...

    Noise from Subwoofer

    I had a similar issue when I had the Velodyne. Adding https://www.crutchfield.com/S-8IJUifNA1Di/p_119MPSW200/Monster-Power-SW-200.html (no longer available but there is probably a substitute) killed the noise. You need to unplug the RCA feeding the subwoofer to determine if it's power feed or...

    Service Brake System message

    My LLY did that a few times along with service 4WD when new and under warranty. Dealer added a ground strap from the cab to the driver side cab mount and I have not seen the message since.

    2022 Allison fluid change?

    Would like information on how you disabled the T-stat in the VB. Is it complicated and did it require any "special"parts? Living in TX, the number of times a decade where the trans stat would be beneficial are countable on one hand starting with freezing temps this week.

    2022 Allison fluid change?

    I've read where the GM fluid is recommended b/c the aftermarket fluid is thicker and leads to issues.
