What is "Heavy Duty Transmission Cooling"

[Pitch1]

2013 !500 Ram express 5.7.
Sticker claims heavy duty oil cooling and heavy duty transmission cooling.
What exactly is the transmission cooling ? Is it just an normal in the radiator cooler,an eternal cooler like an aftermarket would be or both or something else altogether?

Engine and transmission HD fluid coolers are an external unit plumbed to the engine or transmission.
