  1. 07.5-10 LMM Performance Parts Discussion
    I have a 08 lmm and it has an emission compliant tune and an s&b intake. I have the dreaded p0101 code and reduced engine power. I’ve had the maf replaced and the Iat sensor I have cleaned the filter but for the life of me can’t get this code to stay away for good and it’s so random just drove...

  3. Transmission Shop
    07.5 lmm allison 1000. New solenoids all around, new wiring harness, new nsbu, new tcm, new pressure manifold. Get it all back together, reverse and 3rd only with “trim solenoid a” as the code that wont dissapear. Fluid was dirty, new fluid. Any ideas? Plugged up valve body? PFA
  4. Duramax Engine Swaps
    I’ve seen a few posts on here about swapping a duramax into a gas truck; and everyone saying it’s not worth it unless you have a complete donor truck. I have a free LMM donor truck that is complete minus a ball joint and a few body panels. I have a 2005 2500hd with 6.0L, I want to swap the LMM...
  5. Introductions
    Hey guys, My name is Mychal and I’m from AB Canada. I’m not new to the diesel/duramax life but I am new to the forum. Currently have a 2009 CCSB 2500 LTZ, and my last truck was a ‘13 f150 and before that an ‘08 6.4 power stroke. Also have a 2001 ford lightning sitting in the garage that I’ve...
  6. General Discussion
    So my lml engine has blowby and I have a good lmm spare engine with no use for it. My question is can I take the heads off my lml and bolt them to the lmm shortblock? I know the injectors are different, so using the lml heads would allow me to keep the lml injectors then I wouldn’t have to deal...
  7. Towing & Hauling
    Currently have an 09 LMM that I pull a trailer with 5k-9k everyday. I am looking for recommendations for the best tuner for efficiency and longevity. Most people seem to push efi live but who still pushes out good tunes for it.
  8. 2007.5 + (GMT 900) Non Powertrain New Body Style
    I would like to upgrade my factory Bose 6 disc Non-Nav radio to one with a full size screen to use for backup camera and with bluetooth for connecting my phone and retain the steering wheel controls like factory. I don't necessarily need the Navigation since phones do this so well anymore. What...
  9. Gauges, Electronics and Wiring.
    I have a 2008 Silverado 2500HD Crew Cab (LMM) with ~145k miles. Truck is all stock with 2 batteries and 2 alternators and I’ve had zero issues prior to this. I HAD a parasitic drain on the batteries that would periodically draw the batteries down, but never low enough to affect starting...

  11. Maintenance
    Hello, so I have about 200k on my LMM duramax and it’s deleted and what not. I have never had a lift pump on it and I just bought an airdog but have yet to install it. I was just thinking, is it really worth it to have a lift pump especially this late in the life of the truck? I want the truck...
  12. Build Threads
    I had a family friend give me a LMM Motor that he was going to build for a project until he had some trouble and needed to get rid of some thing. It is an LMM Block he didnt give me much detail where it came from out of what year of a truck or anything like that. I have a project blazer that in...
  13. Towing & Hauling
    Okay I mentioned in another discussion I started which I think was in the wrong category about my towing issues. I have a 2008 LMM deleted on 33s and it is tuned but I don’t like hot rodding it or anything like that. I just want my truck to be reliable. I was towing my side by side which the...
  14. 07.5-10 LMM Duramax Powertrain
    I have a 07.5 Silverado 2500 LMM. It seems lately the truck will randomly get stuck in gear or hard shift. Restarting the truck sometimes resolves the issue. Sometimes it works perfectly fine and there is no issue, it usually happens at least once if you drive it for more than 45 minutes at a...

  17. 07.5-10 LMM Duramax Powertrain
    So to start off yesterday evening I went go to fill up my truck at the gas station about a mile down the road. I came back and noticed while it was idling I saw some blue smoke coming out so I checked underneath the truck and saw a small puddle coming then got on the ground to see there was oil...
  18. 07.5-10 LMM Duramax Powertrain
    I’ve had my truck a while now, it’s an 08 Sierra, I’ve replaced calipers and pads all the way around and front brake hoses, but I’m not getting any brake pressure up front, the rears are kind of on and off with their pressure but they stop the truck, but barely ANY pressure up front
  19. EFI Live
    Hey everyone, I'm new to the forums, and relatively new to Desiel tuning. For better or worse, I bought a pre-built/tuned 2008 Sierra 2500 a couple years ago with 150k miles. It's been a good truck overall, BUT I've had a few issues with it I'm trying to sort out. First, a little background of...
