    LBZ: LBZ Oil Pressure Problems

    Well, It's been a long time since I have been active here but it's about that time again. I recently traded my 2003 CCSB 1500HD Silverado for a 2006 ext cab Silverado LBZ that likes to take out turbos. So far I have plumbed in a mechanical guage and verify it is low oil pressure causing the...

    LB7: C0201 and Erratic Shifting

    Hello, I have an 03 LB7 DRW that is throwing codes C0201, and all 4 wheel speed sensors (C0035, C0040, and C0055 i believe). My flashscan pulls these codes from the EBCM, The ABS light is not illuminating and does work, the speedometer has no issues either. I have tried cleaning ground 110 and...

    LLY: Trasfer case stuck in 4 Low

    So i went to drag an immobile truck out of my driveway, had to press the button twice to get it to engage. I only drove maybe 20 feet, and now it won't disengage. No basic codes or 4x4 messages, and I don't hear the shift motor. The button just flashes and goes back to 4 Low, no matter which one...

    Allison 5sp: P0711 and P0872

    Hey guys, I have a stock high-mile 5 speed, and am finally running into an issue with it. About 2 weeks ago, my CEL came on with a P0711, and the transmission temp guage on the cluster stopped working, however you can still read proper trans temperature from the ODB2 port, and nothing else...

    Question: 2007 LBZ van engine?

    I am looking at a 2007 van engine that has a washed cylinder wall, the guy wants $800 for it complete with turbo and injectors. I wanted to build a LBZ for my truck, can a washed cylinder usually be salvaged by boring? Also is there any major differences between the van and truck motor?

    Allison 6sp: A50 TCM in LBZ?

    I have a friend who has accidentally fried his TCM by touching a booster cable to the housing, and he purchased a new one at the local dealership. He was told it did not need a flash. The truck is a 2006 and throws ABS/Brake lights, has no gear indicator, speedometer, and will not shift from 1st...

    Found this in my fuel tank?

    I have had a fuel sump kicking around for a bit that I am just getting around to installing due to barely any rail pressure at cranking or under throttle, and I figured I may have a plugged/cracked pickup. So I drop the tank and everything checks out except this little thing lying at the bottom...

    Replacing Rear differential yoke

    Looks like I'm doing a rebuild of my driveline, a bad u-joint thrashed my rear yoke, and took out my transfer case with it :mad:. I have the old yoke off and the new one sitting there, but I am wondering how to torque it on there. I'v heard of using an inch pound torque wrench to measure...

    LLY: P1093/Surging Idle

    I had started loosing prime to the CP3 a few weeks ago, having to prime it manually before it would start. There were times down the highway where it would set P1093 and limp, and when cleared, it would instantly pop back up for about 5 minutes, it also seemed a little low on power. My idle CFR...

    Leaky Transfer Case Output Seal

    So after replacing my toast transfer case with a used one and filled it with 2.5L of 5w30 mobil1, I have noticed the rear output seal leaking. The seal was replaced, and the output shaft bearings do not seem to have any play in them, but still this leak persists, and it is not pump rub. The yoke...

    LBZ: Good tire/rim combo for stock truck

    My father has a 2007 classic crewcab, and is wanting to upgrade the rims and tires. He doesn't want to have to screw around with anything, that includes leveling kits, cranking the torsion bars, shaving plastic, having them really wide, or sticking out so far they throw mud up the sides:o. Wheel...

    Transfer Case Information?

    So my 263XHD finally crapped it's pants, started to clunk shifting on the fly which progressed to a grinding then even louder bang, I assume this is because my rear seal was leaking and I was lucky to have 3/4 of a liter left when it first happened. I'm guessing shift forks/pads, maybe even...

    So after getting home with a new fuel filter and changing it, I go to prime the filter and after 5 solid minutes of pumping, nothing.

    Random loss of prime

    I have a problem that I thought had went away, but it's back. After my head gasket job, there was two times where after I let it sit overnight, that the injectors lost prime.

    Question: Flywheel Housing

    I'm just about to pull my engine out and need to put in on my stand, is it necessary to remove the rear crankshaft seal on an LLY to remove the flywheel housing? Or is the housing strong enough to attach the stand to?
