GM Transmission Oil Cooler Line Disconnect Tool

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" dia. 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.

Works on 2WD and 4WD pickups and vans with electronic shift overdrive automatic transmissions: 1991- newer 4L80E transmissions, and 1993-newer 4L60E transmissions.
