OTC 7937 Transmission Oil Cooler Line  Disconnect Tool for GM
OTC GM Transmission Oil Cooler Line Disconnect 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.
