Expert Reply:

The Derale Series 7000 Tube-Fin Transmission Cooler Kit with Hose Barb Inlets - Class I - Standard, # D13101, is one of the transmission coolers recommended for your 2001 Ford Focus. There are three possible mounting points for transmission coolers. You have to determine the best place for it by checking each location.

Position A: Mount cooler between your vehicles grille and the AC condenser core for the greatest efficiency.

Position B: Mounting the cooler between the condenser and the radiator still allows for ample airflow, but cuts effectiveness by 25 percent. Installation of a larger cooler unit in this position may help make up for that loss.

Position C: Mounting the cooler between your engine and radiator considerably decreases the available airflow and causes the cooler to be 40 percent less efficient than if mounted in Position A. It is recommended that you purchase a larger cooler to make up for that loss if using in Position C.

I have included an FAQ on transmission coolers as well as an installation video on a similar vehicle.
