Transmission Question, Where can I get one?
So I am replacing all of the TOC hoses on my Super Duty Transmission Oil Cooler, does anyone have any ideas where I might find the HOT line that goes from the transmission to the heat exchanger and has the access for the overdrive sensor.
I need one to install one of the temperature senders.
This is the line that I am looking for, it is the FRONT line and the one on the top,
A-518 transmission is shown and this is what I need, I have an A-727
There are no 1st Gen parts here in Southern California
Thanks
Jim

I will be pulling my 727 and replacing it with a 5 speed in my 12V Crew Cab this winter.
I will have lines left over from my swap then.
PM me if you like.

Ya know, anything you get from a salvage will be 20 year old rubber.
I'd bet you could get one custom made, if you could come up with a sketch of what you need.

I replaced mine last year with one from rock auto for $24. It fit great, has the sensor port and the ends where formed fine. I read on here that someone had one from there and the ends didn't look very good but the one I received look just like the original with great crimps, no leaks or issues so far. great price too.

oh and what are those diagrams from, is that factory or aftermarket directions? My D350 has the under bed cooler and has the same ridiculous looking splice with the the flow doing a 180 to go to the cooler. the cooler looks like the factory option I just couldn't believe how they plumbed it in.
Is this how all the factory installed coolers are plumbed?

Yea...Rock auto has the one w/ sensor port.
Also the "push lock" barbed hydraulic line works excellent. It's cheap and once it's pushed together (no crimping required), you are not getting it apart even if you hang from it. No clamps needed, will not rust, even the ends are brass and very flexible. It's rated to 300 psi and 300 degrees.

That ridiculous looking splice with the the flow doing a 180 is a thermal bypass and is installed to protect your transmission in cold weather and works on fluid viscosity, when the air temperature is above freezing (cannot tell you the exact temperatures) the warm oil will flow through the cooler in a normal manner but as the temps get lower the oil gets thicker and takes the path of less resistance, though the bypass and back to the transmission.
I believe it was added to the original package through a TSB.

Are you sure about the temperature rating on the Push Lok hose
"push lock" barbed hydraulic line, which hose are you referring to?
Push-Lok Plus Multipurpose Hose - 801 257°F
Push-Lok Plus High Temperature Multipurpose Hose - 836 302°F
I think most people underestimate the heat generated by a transmission, today when I replaced all of the TOC hoses on my under bed cooler I found I have several harnesses that have melted along with the insulation on the wires inside that I need to repair where the loom was bundled along with the cooler hoses, it would be like a harness lying against the exhaust pipe, surprised the heck out of me.

I am not following you on the thermal bypass, thought the fluid went through the system regardless of temperature as it will be warmed at the coolant heat exchanger at the engine when its cold?
What are you using for a line from those compression fittings to the cooler?
I was going to replace my lines with hydraulic hoses with JIC fittings, I'm curious now what they actually called for from the factory? I dont think either of my autos have the correct type of lines on them.
And to confirm the rock auto line I have is steel as well.

These coolers are not factory installed, rather they were a dealer installed part. Somewhere on DTR Jim Lane reprinted the Mopar installation instructions showing where the lines were cut, and hose routing. The steel line is cut pointing toward the trans, then the hose loops 180* toward the frame then to the cooler.
