To install the Derale Transmission Cooler, # D12904, on your 2008 Honda Pilot, you would take the long fasteners provided to mount the cooler. The most efficient place to mount the cooler is between the grille and the AC condenser.

The included fasteners look like wire ties and go through the cooler and the component it is mounted to. On the other side, you will place a spacer and then the button lock to hold it in place. The last part of installation is to make the connections with the hoses.

You would connect the hoses in line with your current factory system. The path of the fluid needs to be from the transmission to the factory cooler, then to the Derale cooler, then back to the transmission.

I have included an FAQ article on transmission coolers as well as a video installation below.
