Automatic Transmission - Trans cooler....

I ordered a pretty large trans cooler for my car, and plan on mounting it behind the intercooler. I have 2 12" fans on the intercooler that I want to trigger if the trans fluid starts to get too warm (as well as turn on under boost of 4psi or more)....but my question is : What is the appropriate trans temps for the fans to turn on/off?

Anyone know??

id say around 160-170 thats about where my trans temp stay

im going through the same thing, i will be mounting my trans-cooler with fan (dope style), and running 2 pusher fans but will be turned on upon start up.

i wouldnt mount fans on the intercooler
