ATF cooler line leak

Hey all. Recently noticed one of the metal lines for the at cooler is leaking due to corrosion. Having a hard time finding the part number for metal hose because there are so many different options. Can I just cut the metal line out and throw in some unions and rubber hose? This is a 2017 trd off-road 76k odo.

 

you would do better to replace the whole metal lines because they are prob rusted thin on all of it

 

Yea I’m sure you’re right. The metal line is about 40 bucks at the dealer I believe. Just debating on eliminating the metal line completely using tranny cooler hose to prevent future problems

 

go oem ---- thats cheap and the easiest route
