Aisin Cool Down

1148 Views 6 Replies 4 Participants Last post by  BrianF
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.

No difference as far as I know. Most new autos should constantly be pumping and circulating ATF and though the cooler if the thermocouple is open.

The brother in law has a 1995 Jeep YJ with the 3 speed auto. It will not circulate ATF though the coolant circuit unless it is in drive, which is a funny little thing.
