Need to replace my factory trans fluid cooler. It's the one mounted up by the radiator.
Any suggestions on what to buy to replace it?
The factory one seems to be a little small for my purpose. I mostly use the truck for snow plowing and hauling firewood.

 

The cooler that is really taking heat out of the transmission when plowing and hauling is the heat exchanger on the side of the block under the turbo.

I do have several of the factory coolers behind the grille I could sell you, if you like. Or it would be pretty easy to figure out a way to mount a bigger cooler which you could get from Summit Racing or the like.

 

Thanks for the reply Oliver. What do you want for a factory cooler?

 

Fixed the leak, a hose clamp was loose.

 

Those are the best fixes!

I experienced a recent DOH! moment when my Jeep CRD was leaking coolant near the turbo. I feared it was the oil cooler and upon digging in realized it was above that, around the headgasket so I had a panic attack (I had just replaced that about 10K ago). Digging in further I discovered the thermostat housing was loose. Turned out my mechanic (me) had forgotten to torque it down upon reassembly. Made a hard fix way easy but also a moment to reflect on checking everything and not rushing through...

 

Glad yours turned out to be a simple fix as well.

 

joints defect maybe ?
