Got my Tru-Cool 47391 transmission cooler installed. Took the truck for a drive and the temps never got above 135* on my Aeroforce Interceptor. The same drive prior to changing the cooler showed the temps around 150*. That is with the ambiant temperature at about 90*.
I like the placement behind the bumper as well. It moves it out about 2.5" from the intercooler. It also free's up a lot of surface area in front of the intercooler that the old cooler occupied. Not only did it move the cooler down, but it also shortened the amount of hose from the radiator cooler to the aux cooler, and back to the hard lines. It also reduced the distance the transmission pump has to pump the fluid up into the old cooler. The inlet and outlet of this cooler is about 3/4" lower than the inlet and out let of the radiator cooler.
This is the old cooler behind the grill.
The install is pretty straight forward.
Remove the bumper and set it on a firm surface so you can drill 4 holes.
Center the cooler on the bumper and mark the holes to be drilled.
For the fittings to make the 90*, get yourself a pair of the Edelmann 822660 from your local auto parts store. It requires special fittings since the cooler is a 3/8" inverted flare fitting on both ends. I got mine from O'Reilly (thanks to Tom S. for helping me source the proper fitting). These have a 3/8" hose fitting on them, but the 5/16" rubber hose will flex enough to fit over them. It is a tight fit. I plan on upgrading to 3/8" Super Duty transmission lines in the near future.
Installed. The fittings are about 1/16" above the lowest part of the bumper. That should be enough to protect them.
