I have a 2003 Dodge Ram SLT and noticed that it was leaking transmission fluid. When I got underneath the truck, I noticed that this part was the source of the leak. It consists of two, side-by-side bent tubes (only one of them leaks) with two screws that screw in the front and the back of the transmission. I wanted to do a search on how to replace this part, but I don't even know the name of the part (is it a cooler line?). Was wondering if anyone can identify this part and perhaps point me out to a DIY to replace this part - that would be awesome.
Thanks guys!

 

Yes that would be the transmission cooler lines

 

Those are the lines that run from the transmission to the cooler up in the front of the truck.

 

Thanks to everyone for confirming that those are indeed transmission cooler lines. I tried calling a few parts stores for replacement transmission cooler lines for my 2003 SLT Dodge Ram, but no one seems to have them. Is it because that normally those lines are just repaired, rather than replaced? Does anyone know the best way to repair these lines? I heard about using copper union joints and hydraulic lines. Anyone know of a DIY link to help me repair those? Thanks!

 

this is a dealer only part buddy. welcome to Dodge Forum btw!

 

I'd like somebody to confirm this but the pressure in those lines cannot be that high. I would go to a hydraulic shop and get some hose that is resistant to Transmission Fluid and just cut the bad section of steel out with a tube cutter. Transmission fluid can turn rubber to mush so get the right stuff.

You'd have to flare those lines and put fittings on them to make that work correctly.

You're much better off replacing them with a hard line from the dealer.... but your truck your call.

 

+1 and fixed
