Hi Mcafee,

Where did the line break off exactly? Did you break the radiator?

I had a transmission line fitting snap once near the radiator
in my 740 and there was plenty of room to splice new steel tubing
in for just the cost of a short hunk of steel tubing some and some
junction fittings. I reused the original fitting to the radiator and
had plenty of room to work the flare tool.
There was no need to buy an expensive tranny coolant line from Volvo,
and I avoided the adventure under the car.

Next time you need to break radiator fittings give them a long soak in
Mystery Oil, overnight or longer for good luck.
