I installed a transmission cooler on my Grand Marquis a couple of weeks ago.
I used an engine oil cooler made by Long industries, sold under many different names. I had this cooler sitting around my shop for years, never used. I had to add a couple of pipe bushings and barb fittings to make it work, but I'd prefer it that way:
They make "transmission" coolers of the same dimensions, but those only come with a 5/16" barb fitting on the housing, and if you wanted something larger, you'd be out of luck.
The "engine oil" coolers do exactly the same thing, but you can put whatever fitting you want.

I plumbed the hoses on the return side of my transmission's existing cooling lines, because I'd heard that bypassing the factory transmission cooler can lead to problems.

The pictures are as follows:

1) Here is the cooler with the brass fittings installed, and the brackets bolted in place.
I used 1/8" bar-stock for the brackets, and bent them to shape with a hammer and vise.
On one corner I didn't use a bracket, but instead put a rubber bumper. You'll see why soon.

2) Here's another shot of the cooler and mounts at a different angle, with better lighting.

3) Here you can see why I used a rubber bumper instead of another bracket. It was close enough to the front that it wasn't really necessary, and I didn't want to drill more holes in the car.
As it was, I used an existing hole on the front fascia support beam for the other bottom mount.

4) Here is a side shot of the bottom mount. Once again, I used an existing hole to mount that tab to, thus saving some work, and getting a cleaner installation.

Next, here are some shots from the top, and the finished installation.

I used U-nuts from the hardware store to install the top mounting brackets to the upper radiator support, just as the factory would have.
I don't have faith in the long-term reliability of sheet metal screws on something as heavy as this.

Keep in mind that I had to drill two holes to do this.

Let me know if y'all have any questions about my setup.

Is it just me, or is that AC condenser fairly clogged with dirty or animal hair?

Nice install, I don't tow so I never installed one on this car, but on cars with the in tank of radiator cooler I install them every time.

I actually was told running an additional trans cooler along with the stock one can causcause problems, thus damaging the trans. I bypassed my stock cooler with an aftermarket. Been perfect ever since.

Since the site crashed a few years ago, I lost all of my photos.
Here's how I did my installation with a Long oil cooler.

Just follow the numbers in my above posts to see the pictures in the correct order, so that the captions match up.
If that still doesn't make sense, just ask, and I'll answer anything.
For the record, I've been driving this setup every day for years with no leaks, or any other sort of failure.
I 100% endorse it.

Here is how it all looks, behind that beautiful Mercury grille:

I had to replace my condenser right after I got my car due to the atf cooler portion. That stupid plastic bypass for warmup they used. Love all the aluminum then they just gotta put a weak link on the chain. I was surprised to hear my atf leak required a new condenser.

I see someone noticed the dust debris etc.. in the condenser. You can wash it out there's special cleaner and brushes for it. Depending on where you live it can go from ugly to severely limiting the abilities of the air conditioner. It's more common with outdoor home/business units but still happens to cars too. Be crappy to replace an entire system when the $80 condenser and a vacuum/recharge would've put you back in shape.

HA! There really isn't that much debris on the condenser; I guess it just looks worse in the picture.

One thing I want to mention after running this setup for a few years, is that where I put it happens to be right in front of the ambient air temperature sensor.
Thus, it causes the sensor to report unusually high temperatures to the EATC unit; in the summer, it regularly reports temperatures in the 120+ degree range.

This doesn't hurt anything, but I just thought I'd mention it.
