Re: Stuck Transmission line at Radiator. HELP
two weekends ago when I did the engine swap from my 67 to my 66 pretty much everyline was frozen like you describe.
I'd spray it with some PB blaster or your favorite penetrating oil let it sit.
Then very very carefully and I cannot stress the carefully part. use a pair of vice grips to clamp the line part and use a line wrench to turn the nut. Watch the line to see if it continues to turn with the nut or if it breaks free.
if you clamp it too hard you'll squash the line and if you twist too hard before it loosens you'll twist the line. I'd say use that as a last resort.
