Hey David, the Derale transmission cooler part #D15200 that you referenced does not come with a thermostat or any install kit components but if you wanted a similar option that does have all of that you would want the part #D15500.
That's pretty hard to give an exact answer on but with the install of the Derale Electra-Cool Combo Engine and Transmission Cooler Assembly w/ Fan #D15200 you'd see the fluid stay right around 175 degrees in traffic on a hot day since the fan…

Radiator Fans with 12 Inch Diameter for confident cooling
The 12 inch diameter is a handy size for single upgrades or for pairing two in front of a radiator. Choose pusher or puller setups—some fans switch by reversing polarity, while others may need a shroud to pull effectively. Wiring to a relay, thermostat, or a manual switch is common, and if you run dual fans, plan for noise and power draw at idle.
Installation is generally straightforward. Plan how to run and hide the wiring for a clean look, and use a relay. Some mounting ties or keepers may not hold well, and install pads can break—have spares or alternate mounts on hand. After mounting, confirm the fan cycles on and off as expected.
Yes—reversing the power and ground leads will reverse the rotation. Some 12 inch fans are intended as pushers and may need a custom shroud to work effectively as pullers. Check the fan's shroud design and openings, and verify clearance before committing to a puller setup.
Not typically—these fans are not designed for pulsed voltage and may not sustain operation without a constant 12 volts. Use a relay-controlled thermostat for automatic operation or a manual switch for on-demand use. If speed control is needed, verify compatibility with the motor type before attempting PWM.
Any of those methods can work. A single-stage relay/thermostat can turn the fan on and off automatically, and a selectable manual switch lets you run it as needed. If you're running dual 12 inch fans, relays can switch between series (half speed) and parallel (high speed). Verify clean wiring routes and test on/off before finalizing.
They can help keep the engine much cooler in those conditions. Mounting two in front of the radiator improved airflow over the condenser and engine at idle and in the hot sun. Consider wiring them for half speed with the A/C on and switching to high speed when temps rise. Check for noise at idle and power draw on an idling engine.
