Does anyone else get a clunk from their transfer case when shifting or in reverse? My transfer case clunks pretty bad shifting into and out of park, and when feathering the throttle in reverse. I have a 2020 2500 4x4 LTZ with the Duramax

My 2015 and now my 2020 had/has an occasional clunk when coming to stop. Never had any issues with the drivetrain, so I did not worry about it. Clunk is identical between the 2 trucks, so I am thinking it has something to do with Allison or torque converter.

Maybe it's this...Part of me wants to laugh, but I guess it is possible. I will have to pay attention to my fuel gauge next time it happens.

Definitely not fluid sloshing around, it's metal. Heres a video of what I'm talking about

- Oil Consumption

  Third time. Some consumption is 'masked' by fuel dilution, soot formation, acid formation of blowby gasses. Oil consumed offset by degradation products produced. 2 to 8% How much is that of your sump volume? for Pepper that is 4 ounces to a pint of oil. Why is everyone aware that we check transmission fluids at operating temperatures due to thermal expansion and ignorant or at least dismissive about this issue for the engine oil? Ever allow a motor to drain at oil change for a period of 'overnight"? Measure on the dipstick every quarter hour for say 2 hours and educate yourself. Then let is sit overnight (cooler) and ask the expansion and dilution questions again. 😉
- Gas Prices

  $3.93 for 87 octane. $4.73 for 93 octane. $4.70ish for diesel. But a short drive can see prices swings as high as $5.30's still.

  Thanks for the reply. Im not sure what you mean by the hype Nate puts out. I dont really know much about either trans. I do hear more about the 10 speed transmission having issues but im sure it's only a small % of them that are manufactured. I have heard that the 10 keeps you in the power curve more with less Rpm drop. My stepfather has a 10 speed in his 1/2 ton and im not crazy about the way it shifts and he has started experiencing shudder at 100k.

  That's a good video @Atlas. On point and informative. Highlights the changes over the decades. Experience needs to be informed of pertinent changes to remain relevant. Nice find. Thanks!
