Review on OTC 6579 Transmission Line Disconnect by Richard Cunningham

Surprisingly it worked when the metal version didn't work. I wish the large outer ring that your fingers press on covered the entire circumference so you could apply more even pressure in tight situations, but it works, or at least it worked for me on the 2012 Mustang with automatic transmission. One of the quick disconnects had a factory defect where the hose was crimped which eventually developed into a rupture and leakage onto the transmission oil cooler hose near the radiator.
