Upgraded trans cooler from Fordparts

What's the difference between the one from Superior Solutions and this one?

6R80 Thermal Bypass Valve - Power By The Hour

The 6R80 Transmission has an internal Thermal Bypass that operates much like the thermostat in your cooling system Upon start up, the bypass is closed limiting fluid flow through the on board auxiliary transmission fluid coolers to help get the transmission up to temperature. Once it reaches its...

You got me. The Superior Solutions part is a machined unit with no moving parts. It allows full flow at startup. This is nice in a few ways on top of maximum cooling, the first one is you can check your fluid level at first startup because fluid is flowing to all parts. With the factory thermo, you aren't supposed to check until the until fully opens around 200 degrees. That will take a long time idling in your driveway.

The picture you are showing looks just like the factory unit I replaced. Maybe the one you've pictured has a lower opening temp?

I really am not sure either why they would look so much different, or what the difference between them is.

The more I look at the one in your link, the more it looks like the OEM replacement and nothing would change temperature-wise.

I read somewhere that the ECM limits torque until the trans reaches a certain temperature. So, if it never gets there with the thermostat mod it might drive a little different.

203 is pretty good. You have to remember the fluid circulates through the radiator first. This is done to get the fluid up to operating temp quicker, heat exchange occurs between the engine coolant in the radiator and the trans fluid. The bad part is as the radiator starts to heat soak under load it puts more heat into the trans fluid which is then extracted via the secondary trans cooler. Towing puts a lot of heat in the truck, its going somewhere, if the airflow can't take it all out it's going somewhere else.

Also, the OEM temp sensor is in the valve body, this location isn't a good indicator of return temps. If you want to know how much change your actually getting you would want a sensor mounted in the pan, or in the return path.

The valve body is in the pan. I just did mine, solenoid 4 TC went. Then me valvebody has 3 bad solenoids n fried my trans. Fun stuff
