Oil lines that runs into the radiator, what is it for?
 

While replacing the radiator, I had to remove 2 oil lines that run into the radiator. Both on the passenger side of the radiator. What are these lines for? Messed the lower one up and need to replace it.

On my 6MT, they are tranny cooler lines.

I have a TIP, same thing?

Yes.

They are your Tip trans lines. The trans is cooled through the radiator
 

If you messed one up, get it replaced before you drive it. If you've pinched the line you could restrict the flow of fluid to the trans.
