Just wondering what they looked like. I was crawling around on the ground under my truck today greasing the zerks. I'm pretty sure I do not have one.

 

Here you go, it is on the driver’s side between the back of the cab and the fuel fill pipe.



I have a leak in mine so I am going to have to find a replacement,
Most of the transmission coolers that I have found only have 3/8” inlet and outlets but I have found some here that look like they might be able to fit the existing housing with some modifications.

I have a Rapid Cool heavy duty engine oil cooler that is rated for 450 HP and I was thinking about adapting it to fit the housing but I need to find out how many BTU it is rated for, it has ½” NPT Inlet and Outlet fittings,

I also have an Allison oil cooler off a hydraulic unit that I could use but it is a but large.

If you have the room, they have some good units with a fan that you could mount under your bed.

I am thinking of getting one of these coolers:

Summit has it for about $200, and its complete with the thermostat. Most of the fan/cooler combos in this price range don't include the thermostat.

BC847 did an install of a fan cooler. Check the sticky it is in there I believe. Jim,was your cooler a dealer option or did you install it. I like the looks of the coolers you posted very heavy duty. I wonder if a fan were added if that would help cool more or would their size be sufficient.

 

I saw one mounted on a Hino cab over that looked great. It was mounted on the drivers side in the front wheel well. The whole package was about 18" X 18" with 3/8 lines, about an 8" fan and was well protected. I have not tried to find out more about it but it would work great as an under be mount.

It came on the truck as an option, there is a fan above the cooler and it is controlled by a thermostatic switch but when I was going through Baker, Ca and it was 128* outside and it was not on I decided to control it with a switch.
It sounds like a vacuum cleaner when it runs.

 

that is the same way i have mine hooked up. With the fan on i won't see temps above 150 when towing.

 

Here's a few pics of my setup. I am using A B&M unit that has 1/2 ports.. I am having issues with the temperature though, fan is supposed to kick on at 175*.. And the guage has read 200 and hasn;t engaged.. So, I don't know, think the guage is crazy, or I might put the guage before it goes to the heat exchanger..

And the heater hose was just temporary. I have replaced it with good hose now..

 

From dodge is was called the "super cooling package"

 

Was thinking the same thing Jim! Hydraulic coolers are generally made to handle a bunch of flow (like our tranny's pump) and are usually a bit cheaper than "tranny coolers" of the same size...

Was looking at a huge cooler in the JY a couple months ago that was roughly twice the size of our under-bed units, with 3/4" fittings. Unfortunately, like you mentioned, I wanted to check the rating and couldn't find a plate on it anywhere...

 

I like the custom grille you made to protect the cooler, is it supported anywhere other than the frame rail?

What is the cylindrical part next to the transmission? Is it just a chamber for the temp sender?
