I'm talk one failed on my 2016 longhorn and on 08 megacab. They started to put them on to get fluid up to temperature for fuel efficiency. At least what I was told.
All my old Mopars I've removed the thermostat and bypass them. cuz it's a failure point of their Transmissions, the bypass gets stuck shut and does not run the fluid to the cooler, but this new style I don't know how or if there's a bypass for them
