I have a 2014 T&C with leaking transmission oil cooler lines. As a hobby, this year I started doing a lot of my own auto repairs, so I was thinking of replacing the lines myself. Surprisingly the lines are very accessible and it doesn't look like there's too much to the job. Having never done it though, I wanted to ask those that have... Is there anything specific to watch out for on this job? (Short of replacing any lost fluid) Do these lines need to be bled or anything after replacing them? Or does it not matter if air enters the system? Thanks in advance for any feedback!
