Transmission cooler line

**bakery07** · 08-13-2016

Which line is the feed and return for trans cooler line? I've searched but didn't have much luck. I need to replace a line that is leaking.

Is the line leaking at a crimp or at the connection to the trans/radiator? My GXP started leaking at the trans on one line and the radiator on another shortly after I bought it. A little research on here led me to remove the line and replace the o-rings at each end. That solved the problem. It has been leak free for years since.

Looks like its at thre crimp or near. Line was pretty nasty with corrosion

They are a dealer part that's where I got mine or a junkyard if you can find one.

^ You can get the trans lines aftermarket. The first one on the list is dorman and it says it is the lower hose. the second one on the list is the upper I believe. it has the longer length after the bend. These are 04 up results.
