    Lift Pump and Sump Install Issues

    Ok I installed my new FASS 150 lift pump in the LLY and put in a sinister diesel sump kit at the same time. I followed the directions on both as well as a couple videos I watched. Everything went together nice and I let it sit over night with a full tank to ensure no leaks. Started it up and...

    Right on fellas. Just trying to get as much info as possible before deciding which route to take.

    Limped the Trans on the LLY

    Another question Are all year 5 speeds compatible? Meaning would an 03 LB7 Allison work on my LLY? I know the 6 speeds aren’t due to computer programming etc from what I read. I’m looking at possibly buying one from a salvage yard and rebuilding that if I can get one cheap.

    Limped the Trans on the LLY

    No I’m def not looking to skimp. If I tackle this it’s going to be a do it once and done I was just shocked at the price differences.

    Limped the Trans on the LLY

    Thanks all. Looks like kit prices can be all over the place. Some for $1200 and some coat more than an average rebuilt by a shop. I guess different components really come into play. Anyone know if there is any specialty tools and/or electronics I would need to tackle this?

    I tend to cross the line from time to time as confirmation where it was haha.

    Limped the Trans on the LLY

    I’d call it an issue not a problem just yet haha. So you’re saying it’s not your average DIY type project then.

    Limped the Trans on the LLY

    Well it happened. I have been running the level 4 performance tune on the CTS2 on my 05 lly and was running a dump trailer, not too heavy maybe 3k lbs or so and getting on the freeway it slipped and went to 4th gear only limp mode. I erased the code and put it on 3 the towing tune instead...

    Thanks. I originally wanted a short bed but I didn’t want a big payment and the diesel market is crazy right now, at least in CA especially for LBZ thus my LLY haha, so I settled on the long bed. It’s a bit of a bitch in tight parking lots but I gotta say I like it now. Feels even more like a...

    Gotcha, thanks. Def not worth that much to me to see accurate boost. Little disappointing but as long as the truck is running right and there isn’t a boost issue I’m fine with not knowing exact psi I guess.

    The kit I got with the egt probe is the expandable kit so I think that’s half of what you listed then but still, really need to think if it’s worth it at that price. Whole lotta other ways to spend that money haha

    Thanks. Yea I have the egt probe already. Dam so there’s no way to “unlock” the stock sensor to read passed 22 then? That edge probe is probably another $130 like the egt which is high enough to really question its worth haha

    So does the sensor limit the boost to 22 or only reads up to 22? Either way how would I fix that?

    Thanks. I currently have it on the performance setting, number 4. It has 5 total; stock, economy, towing, performance and extreme. So pretty much 3 and 4 would be the only two I use but I have tried towing yet and don’t want try extreme ad I know it will only do damage so I keep it in 4 which I...

    Just recently bought my first diesel, 2005 Chevy long bed 2500 LLy. Truck has about 140k miles on it and was stock when I got it. Over the past couple weeks I’ve put on 4” straight pipe exhaust, 3” MBRP down pipe, S&B knockoff turbo inlet mouthpiece, egr blocker plate with fingers stick, pcv...
