    6l80 flares, thunks cold upshifts

    I’ve read thru the 6l80 threads but haven’t seen anything exactly like what I’m seeing with my 2009 Yukon Denali XL. The truck has just under 164k miles. 1. When cold and under light throttle or if I have to lift throttle slightly just before a 1-2 or 2-3 up shift, the transmission will shift...

    Considering a 5.3 to 8.1L CI Vortec 8100 L18 swap for a 2007 Yukon XL 1500 SLT

    Hi Everyone, I'm currently considering swapping out my 5.3L V8 which has an ever-existing oil leak off the back of it to either a 6.2 Vortec or even possibly a bigger engine like the L18 8.1 Vortec engine. There's a business that "remanufactures" the engine (found here ) and it seems like it...

    Resale value - Will we see a disaster?

    As we see these overly inflated prices on used cars and even new cars where dealer ask for thousands over MSRP I'm seriously wondering what it does mean for the resale value and appreciation down the road. What do you guys think? 1. Which Trim Level (or even what specific features) will help...

    Another 6.2 for 5.3 swap going on.

    My 5.3 suddenly started blowing large clouds of blue smoke on startup. After a mere 220k miles I think it's done. I walked into the cloud to smell and I think it's got a tinge of coolant too. Whether it's getting coolant into the cylinders or not fixing the cylinder heads is enough expense...

    Better startup with higher ethanol

    2011 Yukon Denali L94 6.2 Flex Fuel 160k miles... I had some stumbling on a dead cold start up after filling the tank a while back. Cleaned the throttle body and it ran better for a bit, I think it just brought up the idle till it recalibrated. Then I ran a tank of ethanol free premium and...

    2008 Escalade intermittent crank no start

    This has been going on for a couple of months now... if we drive it for 1-4 hours intermittently it will turn the engine off when coming to a stop. It doesn’t sputter, it just dies and will not restart until about 1-1.5 hours have passed. It will always restart after that period of time. And I...

    6.2 Hesitation

    Hey guys, I've got an 09 Yukon Denali that seems to have a slight hesitation/putter every once in a while when leaving a stop sign or a slow roll from idle. It almost feels like there might be a brief misfire but no codes are thrown. Engine temperature doesn't seem to be a factor since it...

    Service Battery Charging System

    So, My 2009 Yukon Denali throws the "service battery charging system" message on a daily basis. The little red battery light comes on as well and stays on for varying times. The message seems to only come on while the truck is idling or moving at slow speeds (like when I drive down my muddy...
