One of the two lines is leaking. Are either lines under pressure when the vehicle is off? I found a video to replace these at and it looks pretty simple. Any caveats doing this repair?

Should I stick with the Mopar part or the Dorman 624284? Dorman has a limited lifetime warranty, Mopar is 24 months.

Mini-rant: Unbelievable that a 7-year old vehicle with 100k miles has this issue. I run my cars until they die, 20+ years, 300+k miles, but this is the first time I've ever had transmission cooler lines leak.

 

I just replaced them they were pretty easy but I did not have the one e clip in correctly and the line popped out at 70 mph transmission fluid everywhere. I fixed that went to fill ot up with fluid and can find out how much it will hold. I have 11 quarts in so far but don't know how much it will take to fill it up ? Any one have an answer for that all I am seeing is 10 quarts but I have 11 in and its not touching the dip stick yet

 

You must have the engine running to measure the transmission fluid.
