Lifter tick caused by going down hill

[Joe Merchak]

I have a 2022 2500 with the 6.4L and 8 SPeed trans. I live on a large hill and for the most of it I am not on the throttle but the trans keep it in a low gear. This makes the engine rev high when cold and causes my lifter to make all kinds of noise. I been lately putting the trans in N and that allows the engine to idle and is smooth and no noise. The engine has 55psi of oil pressure when its happening but I guess it not in the right areas when the rpm go high. Is there any way to stop the transmission from holding the gear and keep the revs so high. I dont need engine breaking, its not that steep. It does not sound good so I can imagine what kind of damage its doing. It does not happen once the engine is up to temp, only cold.

That sounds more like manifold bolt issue then the Hemi Tick.

AmsOil Signature vs Penns Oil Platinum?

Alright, this weekend was vehicle weekend! Changed my wife's oil, cleaned and detailed her car. As a side note, i swaped her car to Royal Purple (they didnt have PUP) and its amazing how much quieter the engine is with good (decent) oil...as opposed to crap. Now on the the beast! the change is...

Yea i read all of them, I dont get a tick when started, I dont get a tick when I drive the road in front of my house thats flat. I only get it when going down hill, no throttle input and when the trans keep the motor over 2000 rpm. Remember, when its happening and I switch the trans to neutral, it immediately stops and the engine is smooth and no tick. I will record the sound the next time I go out with a cold motor.

Cold motor, could it be piston slap, instead of lifter noise?
