Yes you do need to replace the hard lines, but you can temporarily patch it until the correct hard lines show up (dealer item, it took mine about a week to get there).

Order the hard line, the washers for the banjo fittings on the transmission, and a set of new grommets for those little brackets (it's very cheap, the whole thing should be less than $100). In the mean time you can cut out the damaged section of tubing (tubing cutter) and insert a short section of hose with a couple of clamps. I did that for a couple of weeks without any problems.

I know it's a giant hack, but it should hold together for a while if you need to use the car while waiting for the parts. However, I was more relaxed once I fixed mine correctly.
