I’ll see if I can find the H/EX on my truck but if you look it is given to separate part numbers (Heater hoses)I'm not sure why they would exclude this feature for one year, and then pick it up again the following year, especially since it's an integral part of their EPA qualification package. But I did check and the Mopar site lists the heat exchanger for 2016 as well: https://www.wholesalemopar.com/v-2016-ram-1500--big-horn--5-7l-v8-gas/cooling--transmission-heater

If they were separate unassociated parts they would have different names and diagram listings (#4)
My understanding is the three-way heater valve was faulty and on recall and they didn’t have a replacement at the time.
The three-way valve was the source of the heat exchangers convection, correct ?
The heat exchanger part number shown in the diagram is only after 02/12/2019, other heat exchangers linked are for 6 speed transmissions.
Other opinions have complaints regarding the heat exchanger because the transmission generates heat on its own and because of its EPA designation.

It could be just my misunderstanding that instead of not having a heat exchanger that I do not have a three-way valve present.
