    04 6.0 to lb7 swap problem class 2 data

    After having issues with locking multiple LB7 ECM's, I have gone to removing the ECM's and using a bench harness for all LB7 ECM flashing. I got tired of having to send the ECM's back to SoCal, and have NEVER had an issue with a bench flash. I got my bench harness from...

    05 extended cab seat question

    Which seat position are you talking about the fronts or the rears? I would bet the fronts from the CC would fit in the EC. The rears will not. I have not tried this, but I have both a CCLB and an ECSB, both with captains chairs and the front seats seem identical.

    Buying an LB7?

    The replacement injectors are because the originals failed from factory. At this mileage your are right at or just beyond the point miles wise for needing new ones. I agree its too much $$ without the injectors already replaced. FYI, when buying ANY used lb7 I ask to see the receipts when...

    Generator talk

    I know everyone thinks bigger is better, but if you do not have the load, correct size is best. 10kw may be too much and the engine will loaf if not fully loaded. Add up the loads and consider diversity. Will the hot water heater, stove, and dryer all be on at the same time? If not, you may...

    Anti seize

    Be careful of the copper based anti-seize on aluminum components. I had an aluminum wheel crack from a wheel stud hole on an old 8 lug Suburban. That whole set of wheels had corrosion pitting on the aluminum coming from the holes. I had liberally used some copper based anti-seize (SS-30) on...

    Ignition Cylinder/worn key

    If the new key does not work, you can get a new cylinder from GM. The dealerships don't like to do it, but the cylinders come with pins which will reset the core to your original VIN. I had to do this when my truck was broke into last year and the column was trashed. From memory, it cost...

    Allison 5sp: Erratic shifting issue

    Is the truck on an incline when this happens? May be an issue with the park pawl inside the tranny.

    Truck takes forever to warm up

    It has all been said previously. My LB7's NEVER warmed up (and produced heat) without the high idle and the winter front on both the bumper and grill.

    Lb7 turbo upgrade ??s

    I have gone with S366's in both my LB7's. The first was an HTT 366 with the SS exhaust side and waste gate. The second is the one listed in the signature for Emma which has no waste gate. Both were run on stock CP3's to start and lift pump setups similar to yours. I liked both of the setups...

    Heater hoses at heater core with twins

    I had a custom blanket made by Levi for the triple hot pipes, and put heat shield on the heater hoses.

    LBZ: Oil leak, but what part?

    Trans rear cover to t-case gasket?

    Thermostat thought...

    What about adding an electric pusher fan for the trans cooler? Force the trans cooler to work. I have had similar problems in AK, where I can get high trans temps at idle or in traffic but NEVER get the fan clutch to engage because of lower ambient air temps (that problem was solved by getting...

    Quiet 4" exhaust

    I have had 2-4" systems, the first was a Banks on an 03, the second was a Diamond Eye on an 04 LB7, both were downpipe back. I'm not sure how that would work with emissions deletes on the LLY. Regardless of the emissions stuff, the Banks is a really nice quiet system. There is a premium, but...

    LB7: Electrical issues

    As is stated above, it could be a wire rub, but you may have 2 issues. The "...door ajar", and dome light issue may be a bad body control module. It cost me a lot of $$ one time to get the dome light to go off....

    Aftermarket exhaust system

    Fill out your signature. If you have a Federal Emissions LB7, not a Cali truck, you cant find the exhaust system you are looking for because you don't have a cat. I have run muffler systems on both my trucks, and like not having the excess noise or drone, just my 2 cents...
