Review on 🛠️ Efficient OTC 7937 Tool for GM Transmission Oil Cooler Line Disconnect by Frank Bruton

Used on a 2003 GMC Sierra work truck. Transmission 4L60E. There is no physical way for a normal sized person to reach into the available space to disengage the clamp and pull on the transmission cooling lines from the transmission side. (Long pickaxes and holy patience might work from below, but oh my.) Press the tool partway against the part of the cord you can reach and slide it down the cord. I even did a few twists and a 90 degree twist and managed to keep the tool in line. Then make sure the clip is fully seated on the leash and using your hand or long curved needle nose pliers, squeeze it until the barbs are showing, twist and pull the leash.
