E67 fan 2 control by trans temp?

[pontiacjeff]

Hi, I have 2 electric fans on my LS4 swapped Montana all wheel drive. Actually, three. Two small fans mounted diagonally opposed on the radiator and a third fan mounted on the trans cooler behind the front bumper and ducted to the front of the car. I want to turn theTrans fan on by trans fluid temp. Independent of the engine cooling fan. The engine cooling fans are on fan one and the trans cooling fan is on fan too. Is it possible to do this somehow? Does it need to have a new code written? Sorry for the typos. Using voice text while driving and tuning! LOL Don't tell the cops.

easiest way is to prob get a stand alone adjustable temp switch to trigger it

I know, but I hate adding a bunch of "stuff" if it can be done with the hardware and software already installed.
