    I was replacing my oil pan and exhaust system when I noticed that the top of the oil cooler lines (55037624AI, I think?) were rusted out and leaking. I think I bumped it a little bit because now it's leaking more than I'd prefer it to be and it leaks directly onto the exhaust. If I drive it around I'm gonna have a smoke show.
    Can you replace any of the steel portion using transmission lines or anything like that? Or will the heat from surrounding devices melt it? Is there any form of cheap affordable way I could replace these cooler lines? I'm looking at 450 Canadian Pesos and 5 day shipping unless I can find an alternative. The fittings that go into the transmission look like they're gonna be a bit of an issue too. I GREATLY appreciate any help possible. Thanks.

    Welcome @BlackHazard ... the rusted sections of the metal line could be cut off and replaced with transmission cooler hose and clamped with worm gear hose clamps. This could be a quick temporary or permanent repair as some sections of the metal lines terminate into transmission cooler hoses. Keep the transmission cooler hoses away from sharp edges or hot exhaust or rotating fans or pulleys etc.

    Thanks for the welcome :)

    I was worried that if the transmission hose gets too close to something overly hot I might have to worry about it melting? Or am I being overly concerned? I believe it was pretty close to the exhaust but I might be remembering wrong.

    If the hose too close to the hot exhaust pipes it would be a good be a good idea to just reroute the line. As the heat can dry out the flexible hose. As aggrex suggested a flexible transmission hose would work just fine, although not as a permanent solution. Even using two hose clamps on each end would give some added security. Aftermarket transmission lines should be available.
