Hey there. I am doing an engine swap and while I have it all disassembled I have a question. I was reading a long post a while ago with strong and varied opinions about transmission coolers. My jeep has one from the previous owner. At least I don’t think it’s stock. So the question is, should I just hook it up like it was, or should I get rid of it? I occasionally get out but it’s mostly a daily.

I added some lines for the transmission lines. I’m more sure of the flow direction but I’m sure someone here does

 

That looks factory. I'd leave it.

 

Here is a different angle.

 

Keep it. (It does look factory)..

 

Mine has one just like that. I did have an issue when one of the lines failed and left me stranded but that was easily fixed and hasn't re-occured.

 

That's a factory cooler, upgrade to a bigger one.

 

That IS an oem cooler

 

Sounds good. Thanks y’all.
