Aisin Cool Down

I'm wondering what is the best way to cool down the Aisin transmission?

1. Idle in Park,
2. Idle in Neutral.
3. High speed idle.

The reason I ask is that yesterday I had to backup the trailer quite a bit and saw the Aisin trans temp at 195 when I was done. I wondered what I should do to get the trans temp down. I thought should I just turn it off or is there a better way?

We have a 2015 Ram 3500 Cummins/Aisin SRW.

High idle. 195 isn't hot, don't worry about it until 210-220.

Do you think it should be in Park or Neutral? Or does it make any difference?

No difference.
