    new head gaskets, now runs rough and smokes

    If you can get a video that might help us figure it out. Where about in Idaho are you? I am in the Treasure Valley and might be able to come look in person with my scan tools if you are in that general area. I tend to agree that it is unlikely an injector went out, unless they were...

    Classic Prices-WTH???

    So basically all the 6-speed conversions use the same GM operating system, known in EFILive as DF6. I think it is always OS 15196784, but there might be others. DuramaxTuner uses transmission segment 15196778, PCMPerformance uses segment 99062821, I forget what Suncoast uses, but they all work...

    Classic Prices-WTH???

    If you do get a LB7 or LLY, you can do the 6-speed conversion yourself. I have 3 converted transmissions: a Suncoast, a Duramax Tuner, and a DIY setup. IMO there is no reason to get the Suncoast kit. It's locked, and they won't adjust tuning for you. The Duramax Tuner kit uses a LML valve...

    Is this Normal?

    I think Mr. Jack Stand Racer said something like that, but it isn't true for the LB7 ECM at least. I have a log of my brother's LB7 breaking traction and picking up RPM at IIRC over 2500 RPM/sec. So quick it spun the balancer (sheared the pin). Neither the ECM or TCM did anything to attempt to...

    Another '03 LB7

    I keep going back and forth on that. The SAC00 and SAC45 cost basically the same, and the 45s leave some potential to turn it up down the road vs the SAC00. It would be easy to leave it stock tuning, but I don't mind writing tunes. I already wrote one for my brother's truck which has SAC45s...

    Look what I found in the glove box!

    Another '03 LB7

    It looks like the Knapheide KSS was similar, but didn't match the body as well and was a bit taller. Can't find their old catalogs, maybe this was a different model? But I suspect it was a competing brand. I had no idea they made a short bed version. I've only ever seen 3 in real life...

    Another '03 LB7

    Picked up a 2003 GMC Sierra 2500HD CCLB LB7 4x4 with a utility bed on it. I have always liked this style of utility bed where it matches the body lines instead of just being a big square box. It needs injectors BADLY, so I towed it back to the farm: The body is a bit rough, and it needs some...

    Allison 6 spd shifts into gear and drops back out.

    Dang rodents! I had to fix a couple wires on mine a while back. Even if they don't look like they can touch/short, it seems things just get glitchy.

    06 LBZ Slipping Out of Gear

    Well, at least you've gotten to the bottom of it now. Thanks for posting the photos, everyone loves a bit of carnage!

    06 LBZ Slipping Out of Gear

    Yes, something is broken on the driver's side. This is the point I'd personally throw in the towel and have an axle shop deal with it, but if you're ambitious you can pull the driver's side axle shaft out and see what you find. If you do, take photos! Sent from my FlashScan V2 using Tapatalk

    It could also be the output yolk. The problem is definitely behind the transmission. Sent from my FlashScan V2 using Tapatalk

    What did you do at work today?

    Looks like a nice setup! We have a farm on the Snake river. When you come back to Idaho, boat on up and we'll feed you all the homemade desserts you can handle. Sent from my FlashScan V2 using Tapatalk

    06 LBZ Slipping Out of Gear

    Since the speedometer jumped up with RPM, that sure sounds like the transmission and transfer case are working, since the speed sensor is on the transfer case tailshaft. I'd personally start looking for the problem rearward of that speed sensor. Could be the output shaft splines, driveshaft...

    its time...

    I personally think you could skip the pushrods, especially on a budget. I am running the SoCal beehive valve springs, have spun the motor as high as 4,800 RPM, and am using the stock 350,000 mile LB7 pushrods. I have over 50,000 miles on the built motor so far, and they are just fine. Maybe I...

    LML Steering play 11-1 Gearbox wore out?

    Your 325/60R20 tires are a smidge bigger than what I run (35x12.5), and I am lucky to get 50k miles out of a steering setup. Large tires are hell on the GM steering system. For what it is worth, I put a RedHead steering box in about 50k miles ago and it is completely trash now. Swapping it out...

    Outside temp

    The mirrors do fail, especially now that they are pushing 20 years old. You can grab replacements on eBay or at the junkyard, and should be back in business.
