Hi,

I have the factory heavy duty tow package, but is this a Tranny Cooler?

No, that is your air conditioner condenser. The stock trans cooler is in the radiator. Auxillary trans coolers are usually small (about 10x12).

I'm seeing what looks like two other lines going behind the condensor. Generally a factory installed auxillary trans. cooler is in between the radiator and condensor (at least this is what I was told). You may have this.

with the 2 extra lines there I would say yes. follow them back, they should tie in to the transmission lines

You can get a print out off all options that came with you truck when it was new by going to the dealer parts person with your vin and they can print a sheet out for you.

Here is a picture of where your trans cooler is. This pic is of a V10 engine. I would think the V8's would be the same.

The V-10 has an extra-thick radiator and the trans cooler is thus mounted as shown in above image.

Smaller motors have trans cooler between condensor and radiator. Look for two hard lines going in to that space from passenger side.

The V10's is mounted up front, the V8's cooler is between the A/C and radiator

Think it will help the tranny more if I put another aftermarket cooler on it?

A total of 3 coolers? Radiator cooler, auxillary cooler, and another auxillary cooler?

That may make the fluid too cool.

The stock trans cooler is located within your radiator. If you want to prolong the life of your transmission it would be a good investment to buy an Aux. cooler. They're not that expensive and will help your tranny tremendously. Silver_DodgeRam can help you out a lot with this since he has an Aux. cooler on his Ram. Here is a link in which Silver posted that may be helpful:

Click on the link about halfway down the page and you'll see his schematic of the Aux. Cooler installation. Hope this helps you out.

Auxiliary cooler, as above, should have been on all auto trans vehicle of every sort since first developed in late 1940's. Trans will live longest with fluid (measured at sump) at 150F. Add cooler downstream of radiator tank cooler, and then add an auxilary filter (such as MAGNEFINE). See www.emeringent.com. Very high quality piece, carries a FORD and TOYOTA part number for inhouse dealer trans rebuilds.

After that, change fluid annually/25,000 (completely, not just pan drop) and it ought to live with any reasonable towing, idling, etc that is hard on trans temp.
