Transmission Cooler Addition-------

Yesterday I loaded a bunch of scrap metal in my truck. In doing so, I also removed the plastic tanks off of my F150's old radiator. This pic shows the trans cooler that goes through the radiator. It is much smaller than I had expected. Mine has the bigger radiator in it as well.

It doesn't need to be big... Heat transfers quite readily between two fluids rather than from a fluid to air. The problem is the fluid it needs to transfer the heat to is already at 195° so it's little wonder why these transmissions tend to run too hot and fail often.

×3, an external auxiliary cooler can only be good for it.


Edit:
too slow lol

Doesn't the coolant go out through the thermostat housing, through the radiator and back in through the lower hose?

The stock RBV wet tranny coolers are on the side with the lower hose so after the coolant has gone through the radiator it should be as cool as it is going to get before it goes back into the engine.

No idea how much cooler it would be than the t-stat temp but it should be quite a bit cooler.

I understand what you guys are saying about water cooling the fluid quicker. I was still surprised it was as small as it was. My power steering cooler on my Mustang has as much tube as this does. Ford also put an external cooler on my truck after the radiator, so it'll be fine. Just expected more is all.

You're right (I didn't think of it that way) though it also means the coolant going back into the engine will be hotter which makes the thermostat open wider and the cooling system's capacity can be maxed out easier.
