Recommended Transmission Cooler for 2005 Jeep Liberty

The Derale Transmission Cooler you referenced, # D13503 would be an excellent choice to protect the transmission of your 2005 Liberty. An aftermarket cooler will keep your transmission fluid in the optimal temperature range, below 200 degrees.

The optimal installation position would be directly behind the grille, in front of the radiator and A/C condenser. Because of the plate-fin design of the transmission cooler, plenty of air will be able to pass through it and reach the A/C condenser and radiator behind it. The cooler measures 11 inches wide by 8-3/4 inches tall by 7/8 of an inch thick, so you will need to ensure that there is sufficient space to install the cooler.

I have provided a link to an install video that you might find helpful. The video shows a different part number being installed on a different vehicle, but watching the video will give you a general idea of what the installation involves. I will also link you to some FAQ articles that contain more information about aftermarket transmission coolers.

If you are planning on really pushing your vehicle off-road at low speeds where getting sufficient airflow through the cooler might be a problem, you might be better off using a cooler with a fan, like part # D12742. The unit is 13-5/8 by 10-1/4 by 3-1/4 inch thick, so you would need enough space in your desired mounting location. You could simply install a switch like # D16740 so you could run the fan only when you need it.
