The best place is in the pan itself. That's where I have mine. You can have a fitting welded into the pan to except thermocouple.

As far as whether you really need one, I'd say don't wast your money for the level of bracket of racing your doing. Guys that do run them are heavy bracket racers that race allot of back to back rounds and will run in two different brackets on the same day. The greater percentage of bracket races don't use one. Only reason I have one is because my pan had the provisions for one, and the kids bought it for me as a christmas present.

Trans temp gauge sender in the pan

The fan relay temp sensors are usually of the dry bulb bulb type and usually get strapped to the cooler fins.
You adjust the fan temp controller to give you the desired trans temp on the gauge that is reading from the pan.

If you want the condtroller to sense the pan temp a second fitting for an immersion type sensor has to be added.

Hayden
B & M
Derale
and others make and market a variety of sensors controllers and pans.

Gach,
Having a trans temp gauge and AUX cooler w/ forced draft makes perfect sense on a street car that is seeiny double duty at the drag strip ,especially if a higher stall speed convertor is being used.
Getting stuck in traffic without the extra cooling and a a way to monitor it is a surefire way to burn a transmission up.

Even if you are a test'n tune racer the tendency for some is to hot lap the snot out the car when the competition rounds are not running.

Some of the comp & bracket cars in addition to on board coolers now use an auxiliary outboard pump and cooler that attaches to the cooling lines on the trans as soon as they get to the pits so a quick turnaround can be made.
