    2014 5.3 LMG to 2008 6.0 LY6 - Will the LMG tune be able to start the LY6?

    Or, will I need to swap the LMG injectors into the LY6 intake manifold/fuel rail? Can the ECU correct for the displacement difference?

    Budget rebuild items?

    If I were to eventually find a 6.0 LY6 to swap in, what would be the smart, but budget-conscious items/parts to plan on replacing? Assume its a higher-mileage, but fully running engine. I have no experience doing this, and have been doing some reading instead of working today. Half the camps...

    There's a 2008 6.0L from a 2500 available for $800 near me...

    And as much as I want it, I have no place to store it and rebuild it. Or, swap it out with my 5.3.... sadpandaface.jif

    2014 6L80 question

    @BlackBearPerf Hi, is it possible to program the engine/transmission to keep the torque converter fully locked when the transmission shifter is in Manual Mode? (maybe not in 1st or 2nd gear... IDK) I'm running into some scenarios where I'm coasting to the bottom of a long steep hill with a...

    2014 2-speed transfer case - faint whine when in AUTO or 4Hi

    Finally got some snow the other day and noticed that when I twisted the transfer case selector into AUTO or 4HI I could hear a faint whine after a few seconds. It occurred on a flat dry road at ~40mph and would go away as soon as I twisted it back into 2WD. IIRC, the front differential and...

    Front hub assembly bit the dust.

    Driving home from some xmas lights Sunday night I felt/heard some intermittent weirdness from the front driver's wheel area. Fiance could hear it too, and I figured the hub assembly was going bad. For reference my truck passed its yearly inspection in mid-October, and they did replace the front...

    Need to pull off the upper trim panel to fix some chipped paint. Does anyone have the plan of attack? I did just buy some trim tools to help.

    3rd row seat question.

    I found some matching black Yukon Denali 3rd row seats on Faceballs Marketplace for $100 locally (well... an hour closer than anywhere else), and the seller says that they don't open up if they are removed from the vehicle. Is that on purpose for ease of carrying outside the vehicle, and will...

    Range of cost for rear main seal job at a shop?

    I'm at a little under 170k miles, and "think" I'm getting the inevitable rear main seal leak. It's more of a seap, but there's a definite leak. How much of my piggy bank should I plan on breaking open for something like this on a 4x4? I'm currently watching a few videos to see if it's...

    Aluminum radiator woes - fresh problem

    Fix one problem, five pop up.... while trying to trace a new noise under the hood during startup: I noticed a fresh and very evident coolant leak coming out of the end-tank to core weld. And also the other is spraying more out via the cooling fan...

    Water Pump - 2014 Yukon 5.3 4x4

    Looking at replacing my water pump since I should have done that when I swapped out the radiator last summer, and also replace the plastic heater core T's in my never-ending quest to find out why I'm slowly losing coolant (little bit in the warm months, a lot in the winter... probably* the...

    Brake rotor minimum thickness?

    Where would I find the specs for minimum rotor thickness (Front/rear)? My pads are getting low up front (rears still look fine), but I figured I don't need new rotors this time. I found this info in the 2000-2006 section when searching for the GMT900 info, but I'm not sure if this applies...

    How much voltage goes to the rear defogger/defroster?

    My icey rear window didnt defrost today, and it's been bugging me for a while. I just checked the fuse (30A good) and relay (goes clicky-clack when I hit the button), and the fuse is seeing over 12v on both sides. The metal terminals on the defroster glass are in good shape, no corrosion or...

    Rear wiper arm fell off....

    Lots of snow yesterday, and on my way home from the mountain I tried to remove a bit of the snow buildup. Clicking the switch to run the rear wiper and I heard a faint crack. I just figured that.... who knows. When I stopped at a gas station to wipe off the snow I saw the entire arm dangling...

    Quick AT pan gasket question - Reusable?

    Getting my truck undercoated Saturday at a friend's house (he's a tech by trade, and bought the shop's undercoating equipment to do it on his own), and he said I could do the AT fluid and filter on his home lift prior to the undercoating. Is the transmisison pan gasket reusable? It's not...

    Looking for short 3" exhaust turndown tip

    I'm looking for something like this style, but more like 4-6" in length. For reference, this picture shows a turndown 12" in length. Otherwise I'm going to buy this and modify it to be shorter. I'd rather take the pre-made/lazy route if possible. The goal is to have the tip of the exhaust...

    3" catback exhaust upgrade. Surface treatment questions.

    I bought a 3" catback consisting of T409 pipes & muffler. I also live in NH, where they dump salt & spray/pre-treat the roads with brine. It kills cars new and old. I assume that the exhaust will last at least 5 years, which is probably as long as I'd reasonably expect this Yukon to last me...

    Is there a gasket between the catalytic converter and flex-pipe?

    Buying a new cat-back, and when adding some parts to my cart I see there's a weird ball & socket type joint between the cat and flex-pipe. Is there a gasket that fits in there?

    DVD/CD stuck inside headunit, won't eject, lots of clicking.

    2014 Yukon SLT w/Bose nav screen, single disc slot CD/DVD player. Every function was working 100%. No known issues. All that being said, I went to eject a DVD yesterday, and I can see it peek out a few millimeters with 20 or so loud clicks, before being sucked back into the abyss. The disc...
