I know that my truck has 2 stock tranny coolers, one at the bottom of the radiator and one up by the AC pump. Is it the one up by the pump that is replaced/upgraded. Could some one explain a little about recommended tranny coolers upgrades.
humm, i dont recall one by the AC pump, most upgrade the one at the bottom of the radiator.
--my buddy just added the tru-cool from i think dieselsite, he said it dropped his tranny temp about 30 deg.---thats a huge difference whey your talking 180 deg. to 150 while towing.

I have a 6.0 cooler. In the 2001 (it may be 01, possibly 02) and newer trucks, they have a second aux. cooler in the radiator. I believe the 6.0 cooler i have has to work extra hard to wick away the extra 200* heat of the coolant when my transmission is only running 140*.

The second cooler is out in front of the radiator, not at the AC pump. The easiest upgrade is to add a 3rd cooler by putting it out in front of the radiator up higher than the one that is there, then reconnecting the tubing so that it is in series with the one below it. That is easiest to do, and adds a whole lot of extra cooling rather than substituting a bigger cooler for the one that is already there. The big Trucool, without the built-in automatic bypass is easy to install and adds more than enough extra cooling.
You need to get underneath and inspect the routing of the tranny oil line coming from the front of the tranny to the coolers. Then identify the line going to the existing cooler in front of the radiator and the line coming back from it and returning to the tranny. It is the line coming back you need to cut into. Then connect a new line to the cut line coming from the existing cooler and run it back in front of the radiator to the new cooler, and another new line from the outlet of the new cooler to the cut line running back to the tranny. This puts all the coolers in series; first the radiator cooler, then the old oil-to-air cooler in front of the radiator, then the new oil-to-air cooler in front of the radiator. Along the way you need to figure out how to get the grill off to mount the new cooler and connect the lines. Thats it. I did it, then verified I still had more than the minimum oil flow rate specified by Ford. Be sure that the lines are protected from rubbing on anything due to vibration. I now have plenty of cooling to tow my big 5th wheel in hot weather.

If I'm not mistaken, the cooler at the bottom of the radiator is the power steering cooler. Is it small, approximately 4" x 10" in size? If so, that's power steering. Follow the lines and you should see where they go.
The only tranny cooler is directly in front of the radiator, behind the A/C condenser. What is this one you speak of by the compressor? In the engine bay? Like others suggested, the 6.0 cooler works well.
Oh, and Kris, the thru-radiator cooling started mid year of the 2000 model...I've got it on my truck.

Oops!
Doug, I didn't notice you have a 99. There is no auxiliary cooler in the bottom tank of your radiator, as there is in my 02. Sorry. You only have the single oil-to-air cooler in front of the radiator. You should still add a new oil-to-air cooler in series with that one. Be sure you check to see you have adequate oil flow according to the Ford spec, which I don't know the value of for your truck.
