factory transmission cooler

I just bought a 2018 NV2500 cargo high roof with a V-8 with the towing package. (bought it on the internet and have not picked it up yet) My question is does it have a transmission cooler?

On paper, it has two.  One integrated into the radiator, and a second, stand alone cooler controlled by a bypass valve for high temp situations.

Has a great big one.  Don't need to add or change anything.

 

The bypass valve in the cooler is actually for cold temps.  It bypasses most of the fluid when cold and only when warm does the bypass close and actually flow through the cooler.  Nissan has been running these for decades.  Useful to get the transmission up to temp in cold climates.
