      A:

      Hi Ray, glad to serve you! This part is universal and not vehicle specific. This tool is specially designed to work in tight places. So simple to operate, you can do it with just one hand. After insertion into the quick-connect fitting on 1/2 inch diameter lines, a quarter turn of the tool quickly and easily releases the fitting on the transmission end of the transmission-to-radiator oil cooler line. It works on 2WD and 4WD pickups and vans with electronic shift overdrive automatic transmissions, 1991- newer 4L80E transmissions, and 1993-newer 4L60E transmissions.
