Hi Dave (Volvo From Heck).

I missed this before, but your point on the trans cooling lines is well taken. I took a look, and the cooling line bracket is indeed there on my car. Next time I have the car up on ramps, I'll take that off, and inspect the lines. The cushioning idea seems like a good one. I happen to have some old bicycle inner tube I think would be perfect for this. The bracket piece looks to be aluminum, so opening up the clamping area with a file to allow a turn of inner tube to fit in there should be easy.

In the future, I have aspirations of taking this car on some longer trips in the near future, and would hate to be disabled for something as silly and preventable as a worn-through line. Thanks for the tip.
