Hi,
I`m trying to find a new transmission oil cooler lines for my 2007 4.0 R/T W5A580 (722.6).
When I searching by VIN (1D8GU58657W721917) its appears only parts no. 55037865AH or 55037841AK but it does`t fit. I think those part fits to 42RLE but I have W5A580.
Please help!

Do you need lines between transmission and thermostat valve? If yes, then go to the local hydralic shop and let then make better/custom hoses with banjo fittings.

Welcome to the forum @ Sim0n. When you have a chance, head over to the Newbie Section (<click this) and say "Hi".
Tell us a little about yourself and your ride.
That way we can welcome you all proper like.

55037865AH Sales code (DGJ) is what I found for the 2007 4.0 NAG1(aka W5A580). Verified thru our vendors web site.
These are the long lines that go from trany to the cooler. Not the short ones coming from the side of the cooler to the rear.

Guys!
Thanks for yours numbers - I have to verify that parts.

Few days ago I trusted an ebay and bought that:
39071


But is does`t fit to my NAG1 :confused:

Numbers 55037840AG and 55037865AH looks like this above. Look at the shape.



But here is another shape 55037840AG - probably it`s what I`m looking for:


What do you think?
On Monday I will disassemble it from the car and show it here.

The problem is all the parts catalogs I have(07-11) all have just 1 Pic and that is of the 42RLE hoses.
But they do have the different parts #s for each rig/trany. 4.0~NAG1, 2.8~NAG 1 and 3.7~42REL.

if you order the cooler lines from a Mopar vendor using your chassis number, you are guaranteed to get the correct parts, or take your chances from the internet sellers
but i see some sellers saying there cooler lines fit all variations of the Nitro which is not true, as ScarO says alot of the time the parts image is not correct.
