Default Tranny Cooler is leaking

Hey guys,

Recently my tranny cooler has started leaking. I had it in the garage for a week, and before I put it away it wasn't leaking. I took it out a few days ago and it was running fine, but I noticed a spot on my driveway. The transmission cooler seems to be leaking a little bit. I have a pic, it looks quite dirty and gunked up. There's "sludge" around/in the cooler and you can see where the leak ran down my air-dam. I bought the car with the cooler so i don't really know how they work. I imagine I lost some fluid though, so should I add some or what?



Much appreciated guys

Any clue where it's leaking from? They work just like a radiator. I'd check the fittings first to make sure that they are not the culprit. The input/output fittings are the most likely place for something like that to leak. A lot of coolers use NPT or Nominal Pipe Thread. If your previous owner, like mine, was a dipshit, he might have used the wrong fitting to secure the hose / coolant line to the cooler. It's why I'll never buy another modded car.

Oh crap, sorry forgot the pic. I'll post it up top now
You can't see it in the pic, but the only thing I think? I saw, was a rubber hose going in to the left side (dark side of the pic, of course) and it had dirt and crap all over it too. I didn't see the output hose.

That is the most shade tree mechanic bullshit I have ever seen. And this is coming from somebody who's previous owner did the lt1 intake leak "fix" and left the hood up, engine exposed and it rained.

It looks like a rock hit it. The pic is kind of hard to see. Only way to really know is to take it off.

Oh, lol. Yeah whoever put it on used the backstraps and zip ties on the top. When I take the bolts out and cut the zip ties, I'm gonna need to take the hoses out right? Am I gonna lose a lot of fluid?
