For those of you living in the cooler states, this may seem a little extreme. My, as well as others I know, P/S systems have a difficult time in SoCal. The reservoir will actually overflow while wheeling due to the heat. I flush my fluid every few runs and it is always dark and burnt smelling.
I have installed a Hayden 1678 tranny cooler, which is pretty popular with the 4Runner/Taco crowd for tranny cooling. In addition to the cooler, I have mounted a pusher fan right in front of it. I have run the wires but still need to plumb and wire it. I will also mount an identical fan over the factory tranny cooler. Hopefully this will help combat the CA heat. My plan is to merely wire both fans to an on/off switch though 2 relays. I will turn them on as soon as I leave the pavement as I think that is a better (and simpler) plan than any type of temperature sensors.
Only time will tell whether this helps but I really hope that it does. I will post my findings as soon as I go wheeling again. Here are a couple pics of my progress so far:
