Didn’t know if should be here or in trans. Section.

Working out the ATF plumbing. Have 5.9 service manual, not much help, nor is nearby Dodge dealer. The plumbing was disconnected from the engine and trans. What I was able to discern, there is a check valve on the male end of the short rubber hose(picture) that screws into the factory tubular water cooled heat exchanger along the starboard side of the engine, don’t think it matters which end it connects to. That rubber hose connects to the front, higher up fitting on the trans. with a short rubber hose, I have no clue what kind of fitting goes there?

Thus, the other fitting on the bottom of the round water cooled heat exchanger alongside the engine must go to the air cooled heat exchanger and then return to the aft, lower fitting on the trans?

Is there supposed to be another short section of rubber hose coming off the other fitting on the round water cooled heat exchanger alongside the engine or does a piece of steel tube attached directly?

What kind of fitting goes from the rubber hoses to steel line at the trans. Location? I’m not sure a hose clamp with a slip fit on a piece of .5” steel tube would do the job. Does anyone know how much line pressure a 47 develops?

I would appreciate any input any of you have. There is a place nearby, Tubes and Hoses, that’s has the correct hydraulic bender and can make up fittings.

The metal dodge cooler lines are notoriously terrible.

There isn't line pressure there.

Several outfits make a nice kit with good hose and pushlok fittings to replace the Dodge junk tubing. Those kits are a great value and work great.

I will have to have the lines made for my application(‘55 GMC) so I need to review the alternate fittings available.

Here is the diagram of the oil cooler setup if this can be of help. This is the setup for a 47RH from a 1995 Dodge. The 1997 had the 47RE transmission and its parts are different. As you can see the most of the parts are discontinued. If you need the parts that go into the transmission those are not part of the oil cooler. The connectors mounted in the transmission housing are quick connects and there have been 2 different ones and all are discontinued. The part numbers in order of sequence are 52028468 and 52028469.
