    2008 L76 6.0L engine swap

    Thank you for all your responses. The present setup is OEM for a 2008 Yukon 1500 SLT 2WD, i.e., the L76 6.0L and the M70/4L70-E. I have installed a Range AFM disable OBD port device that cuts out the AFM. You've collectively answered my question re: the trans - stick with the 4L70-E. Re: the...

    2008 L76 6.0L engine swap

    Correct earlier mistake: LY9 should be L96/"G"/6.0.

    2008 L76 6.0L engine swap

    Thank you for your response, Marky. What I'm looking for is total 1-to-1. Not just block fit, but wiring harness, ECM, TCM, etc., e.g., just the lazy man's drop-in. Which of the following non-AFM/DOD 6.0 or 6.2. engines will fit 1-to-1 everything: "K"/LY6/6.0 2007-10 "G"/LY9/6.0 2010-17...

    2008 L76 6.0L engine swap

    Which engines are a 1-to-1 swap for the 2008 L76 6.0L engine? Which transmissions are a 1-to-1 swap for the 2WD 4L70-E? Time to start thinking about a reman or crate engine without AFM/DOD and trans and would like a 6.2L with a beefier trans. If not a 6.2, another 6.0.

    2007 Yukon Suspension Modification

    The general consensus over the last few years is to keep the Z55 AutoRide system. Many have converted to standard shocks/struts only to switch back. I went with Arnott SK-2954 in the front (non-AutoRide); the kit has an electrical device included that "fools" the computer, eliminating the...

    Battery Replacement a Professional Job?!

    An additional long-winded "word" on batteries. I conducted extensive research when setting up the electrical system on my boat (dead batteries out on Lake Huron = very bad). Ignore any marine references that are NA to autos. Short Summary: Learn the basic/critical facts about batteries and...

    How can you afford the cost of a new SUV?

    Just throwing it out there. For $50 an hour and out-of-pocket expenses, I'll check out any vehicle you find on Craigslist or another website (e.g., AutoTrader) within 150 miles of Tucson, Arizona (includes Phoenix; driving time/distance @ $25 an hour/25 cents a mile). Includes complete...

    How to Reset Transmission Control Module?

    How can you afford the cost of a new SUV?

    By way of example only, last year I sold my 2001 Ford F250 Platinum Edition (Lariat) 7.3L diesel after owning it for 17 years, which I bought in Houston, TX with 114K miles on it. I bought it for $21K and sold it for $18K (267K miles). Yes, I had spent a bit keeping it up, but I could and did...

    6.0 Engine and Transmission Emergenct

    I agree re: wiggling the wires. If I was as young as I was when I first started working on cars 65 years ago and could still get up and into the engine compartment, I would have tried it myself. The symptoms and codes screamed numerous electrical issue possibilities, not mechanical hard part...

    6.0 Engine and Transmission Emergenct

    Correction: P0174 (System Too Lean Bank 2); may have been cured by new upstream O2 sensor, right bank.

    6.0 Engine and Transmission Emergenct

    And now, the end of the story. Remember the oil pressure sensor pigtail wire that was frayed and fixed by the independent shop tech without having to R&R the oil pressure sensor switch? The hard shifting that required the TCM to go into the relearn mode? Those two issues were quickly followed by...

    6.0 Engine and Transmission Emergenct

    Problems resolved. It was apparently a coincidence that the transmission (hard shifting) and zero oil pressure problems occurred simultaneously. Or the electrons revolted and enlisted the PCM to highjack the TCM. The oil problem was the harness/pigtail, not the oil pressure sensor/switch. The...

    6.0 Engine and Transmission Emergenct

    2008 Yukon 1500 XL SLT with 6.0L & 4L70-E trans; approximately 155K miles; everything re: engine and trans working great. Parked vehicle for about 45 minutes. Came out, started up, check engine warning symbol. All instruments OK except oil pressure - not registering any oil pressure. No smoke...
