Has anyone installed a Raptor transmission cooler?

[Brian_B]

I’ve seen 230° on the coolant and 245° on the transmission a few times and that’s a bit high for my liking even knowing that’s within operating range. It’s not really that the coolant is putting heat into the ATF, it’s that the transmission is putting heat into the coolant. Why add heat when it’s not needed.

I think you lost me here.

Heat from the transmission fluid is dumped into already hot coolant temps through the heat exchanger. I am going to separate the system so coolant remains cooling for engine components only once operating temperature is reached.

Ok gotcha, I was thinking what was the point of the cooler at all if you didn't want to dump the heat someplace. But what you say here makes sense.

Visual reference below for what I’m talking about.

Thank you
Ford’s approach is odd. Think they might have had a simpler design. They are using two coolers one water, one air. I think you need the know what rating the trans thermostat is to flow to air cooler…

I would still look at your radiator thermostat.

I have a manual, but friends… Tks

Yes the fluid to fluid “cooler” behaves more like a warmer on the Raptor. Once transmission fluid reaches operating temp the fluid is allowed through the air to oil cooler directly. This creates the benefit of accelerating the warm up of transmission fluid temps from cold so that the transmission can operate efficiently sooner. And then when it gets warm enough the fluid is allowed to eliminate its heat much more efficiently through the air to oil cooler versus compounding its heat with hot engine coolant.

@TrailDamage Fully understand.. been a ford guy my whole life and ford has used the heat exchange for a long time.

It sucks and hard sometimes to get around …

Edited TrailDamage l like your knowledge, research, thorough process.. hats off to you

@TrailDamage here are good people. Good product. But I don’t like it go below 180* unless you are going to retune the ECM

But here is a ford cross reference

I appreciate this. I don’t plan on changing the engine coolant thermostat at this time. I believe coolant temps can be controlled once I take the transmission heat out of the equation. This is my first EcoBoost I’ve done this on though so results are to be determined. It’s been a significant benefit to my F-150 with a 5.0 and Whipple so far and I’m hoping for similar results. I forgot to mention I’ll be doing a PPE transmission pan which does aid in some heat shedding as well. I have one on my F-150 and in the winter it actually takes forever to reach transmission operating temps because the aluminum transfers the heat so well.

It includes a thermostat pictured here that opens the flow path to the grille mounted air to oil cooler when temps are warm enough.

Hey TrailDamage. I know you are On top of your project.. I am doing research for friend and going w/ your Braptor cooler.

If you find/ figure out the thermostat temperature rating would like to know…

But found this.. fyi

Anyone looked into or done an install of the transmission cooler on the Raptor? I like the idea of separating the coolant from the transmission fluid as much as possible. I know the fluid to fluid heat exchanger works decent but once things get hot they’re not getting cooler that way, the radiator simply is over capacity at that point.

Here's an option on our website!

I haven’t done too much digging into the set point but I believe it’s around 180-190° that it becomes fully open
