Has anyone replaced the coolant lines that feed the transmission oil warmer on one of these trucks? Have one on the lot that a hose clamp from an adjacent hose rubbed through the aluminum line. I only had a chance to breifly search Alldata and so far have not seen a procedure for the lines themselves.

It looks like the cowl and or upper intake may have to be removed to access the upper end of the lines. May also have to lower the transmission some to gain enough room to remove install.

If anyone has any experience changing them any info is greatly appreciated.

There is a procedure outlined in the repair manual.

Figured I just missed it, since I didnt get a lot of research time the day I diagnosed it. Thanks

Do this from 100% memory;but seeing how Durango and Grand Cherokee were never meant to come apart ;maybe 2019 did away with the double firewall if youre lucky … The E Clips can come out with a pick on the fitting I think kept a steak knife around for those . I believe tubing goes from LH side over the top of the trans and in held into place with bell stud nuts …. It then run up the RH side…

Well, too many lines and not enough room to see very well. Turns out the line that is rubbed through goes to the rear heater core and not the transmission fluid warmer. Thanks for all the replies.

Well the boss ordered lines yesterday, and they are available separately. So not knowing which of the 2 lines we needed he told them to order both. So the lines get delivered today and they sent 2 of the same line instead of one of each. And of course I need the one they didnt send.

Sorry for the delay in posting a resolution. As I mentioned it ended up being one of the coolant lines to the rear heater core that was leaking. Sourced a new line from the local Dodge dealer and the truck is back on the road. Thanks for all the help.
