I am installing a tranny cooler on my 03 GT. The bottom line on the car is the one I am taking off to hook the cooler in series. The only trouble is that I freaking turn and turn the bolt and it dosent want to come out. I have about 3/4 in of the thread exposed and it keeps turning out the coupling that it screws into hasn't moved and inch. Does this thing come out or what? Any advice would be greatly appreciated.
