I need to replace the end of my autotransmission cooling line. How would I flare the straight steel line to connect to this fitting? Or is there a better way to connect it without buying the $100 BMW line. Btw, this is the $10 piece that goes on the other end up the line. Exact same part except the original one is crimped to the steel line instead of this fitting.



For reference, this is what the other side of the fitting should look like.
