Anyone have an issue when braking (not sure if its downshifting), there is a noticeable clunk that feels like someone bumped your rear bumper? I have just over 1500 mi on the truck and never had this issue till just recently. Happened 2x this week. It is in normal, 2H drive mode.
Any inputs would be great before I call the dealer.

I posted this in another forum as well just trying to get more info...

I wonder if its the slip yoke bump you are feeling. My 2014 had that issue and I pulled the driveshaft and greased the splines of the slip yoke and it totally went away. Maybe see if your dealer can do that for you?

my 5.0 with 10 speed gearbox does it intermittently when going from 7 to 6 or 6 to 5. it f*cking pisses me off a lot. my god damn transmission will go out as soon as the powertrain warranty ends knowing my luck..
