    Considering a DPF Delete: Is It Worth It in the Long Run?

    If you can get a reputable tuner that knows what they are doing, then YES it's a worthwhile endeavor. Modern emissions are a joke on diesels. Burn more fuel to be 'cleaner' and then use ammonia to clean it. You will see improved fuel economy, generally cooler running because you're not...

    Front Struts non-Magneride type

    The newer ones don't seem as robust as the 2007 to 2014 unfortunately, but failure at 49k is pretty crappy. In my experience, there isn't an aftermarket solution that rides as well as OEM, and cost wise it's a not much more

    How are your 10 speeds doing?

    I can say that I love my 8 speed. Its at 185k and has regular fluid services at about 40k intervals - mix of flushes and pan drops. No thermostat bypass and just OEM fluid. My 6 speed is great too, but I've massaged the shift speeds a little which makes it drive better without as much...

    2007 GMC Yukon Denali 6.2

    You could have a purge solenoid for the fuel system that is stuck open. This can a mimic a flooded engine situation. Replace with OEM only in my opinion. Check the throttle body for excessive carbon buildup as well. If you see a black ring around the plate, then brush its teeth with some carb...

    Any 200,000+ rigs here?

    That is impressive! Well done. I have 184k on the same drivetrain, but 450k is a whole new level. What transmission t-stat bypass kit did you use? I love the 8 speed and have found it to be quite durable with proactive fluid / filter changes.

    Coolant overheating 2019 Tahoe - SOLVED

    Can you check the actual temp with a hand held IR gun? Check the upper hose or metal that isn't shiny for a more accurate reading. How many miles? Has the coolant ever been changed? Has stop leak ever been added? A bypassing thermostat will increase the temperature over time and with high...

    What do these codes mean and how do I fix it?

    If it's intermittent or something like a gas cap that isn't right, then sure move ahead and clear them. If there's a repeat issue, it'll let you know. As @Doubeleive stated, these can be tricky, but he listed the most common failure points, both of which are easy to fix.

    2016 Yukon XL Transmission Failure

    I would go the GM Certa transmission route if I were you. 3 yr / 100k nationwide warranty. And, based off the use you seem to do with it, keep it serviced on the SEVERE schedule which is about every 40k or so. Keep the fluid thermostat bypassed for sure and maybe look into a external cooler as...

    Gas filter

    The filter is built into the sending unit and is quite robust. But, if you get a tank of dirty fuel like I did in MT, then you get the joy of replacing the sending unit. I made the trip home, but replaced it once back......it was gross, but really did it's job. The inlet side of the filter...

    Torque converter starting to quit?

    What's the color of the fluid? I'd advise a pan drop and filter change. That'll refresh approximately 40% of the fluid with trans cooler factored in (others can correct me if my math is off). Safest option since you don't know the history IMO.

    Few things I wonder about.

    It's not normally the RMS that fails, it's the rear engine housing cover gasket - the type of gasket that is permanently molded to the aluminum. It gets stiff with age and then allows some seepage due the high quantity/psi of oil that passes next to it.

    2020 Suburban RST

    Do yourself a favor and run 5w-30 full synthetic for best outcomes IMO. It's the recommended commercial oil in the 6.6L that isn't subject to CAFE gimmicks. I have the same motor and have run 5w-30 since it was new to me over 140k miles ago - doesn't burn a drop and never affected mpg in any...

    Transfer case won't shift

    Have you checked the tire condition on all 4 corners? Mismatched brands, excessive wear front vs. back etc can cause binding if on a hard surface without any wheel slippage available. The rolling circumference have to match/be very close. If they aren't, this can cause it to become 'stuck' in...

    Anti seize on spark plugs?

    This is SO true. My brother and I joke about this anytime we have to work with it. LOL

    Anti seize on spark plugs?

    Good information, never thought of using it on spark plugs. I've always used a light brush of oil off a fingertip on the threads and then use the same torque method as @OR VietVet .LOL I've never had a GM plug that wouldn't come out, but it's good reminder to always guage how they react when...
