The item you selected, Derale Radiator Adapter Fitting, part # D13018, is the adapter fitting needed for a transmission cooler for your 1999 GMC Yukon. Part # D13018 comes with a quantity of 2 which you will need to install a transmission cooler on your vehicle.

A transmission cooler I would recommend for your vehicle is the Derale Transmission Cooler, part # D13504. The ideal place to mount a transmission cooler is behind the grill, but in front of the radiator or AC condenser as it will have the most cooling efficiency (see FAQ).

Installation of a transmission cooler on your vehicle is fairly simply. The Derale Transmission Cooler, part # D13018, installs in-line with the transmission fluid return line. First, you will want to find a place to mount it and use the included fasteners to attach through the cooler and to the mounting point. Then, you will measure and cut the hose and connect from the transmission to the cooler and measure and cut another length of hose from cooler to the transmission.

The transmission coolers, part # D13504 and part # D13018 come with directions for installation.
