Very interesting approach on this piece, instead of changing the whole unit I just swapped thermostats. Probably saved an hour of work! The picture is the stock one which has a number 2 stamped on it. The one from the performance package has a 1, I assume this is how the temperature is signified.

Good luck!  Just for reference sake:

Hey Guys. Got the cooler in. I'll do a write up during the week. My only question is about the flow of the fluid as I have it in parallel with the in radiator cooler. The aux cooler is off the perpendicular leg of the T vs how the performance package has it where the cooler in the radiator is connected on the perpendicular leg of the T. Is there a huge difference in how it flows? I'm thinking it's fine. Fluid has to go up to flow through the stock cooler so it should be easier to go through the new aux cooler.

Anyone?

PM crash712us, he may have some insight into this question ...

The 160 degree thermostat with the aux trans cooler really drops the trans temps. During normal driving in light traffic, the temps hover around 150 -160 which is 30 - 40 cooler than before the install. It is a bit cool now in Chicago so I'll will have to wait about 5 months to test it out in the summer heat.

Sweet!  Based on reports from previous installs, I am sure you will be very happy with this upgrade during summertime/heavy traffic as well

Nice work, looking into doing this on my Flex as well as the oil cooler.

Is there a thermostat on the version that just runs through the stock radiator?

If so, can it be changed?

I believe stock also has a thermostat as referenced above but have no idea of the temps that are set for.

Yeah, I have not seen specs listed for the transmission TStat anywhere.  Will keep looking.

My transmission stays around 200 degrees but my coolant temp is around 180.

There must be a thermostat trying to keep the trans at 200.

This DIY says the thermostat can be changed in the bypass assembly.

Has anyone changed this without adding the external cooler?

It should be matched to what the water thermostat is, otherwise your just cooling it to heat it up again. From the research I have done, stable temperature is better than lower temperature that fluctuates. That said I would believe it's worth changing the trans thermostat if your water thermostat is 160.

If you just want to replace the thermostat in the bypass valve, you could be in luck!
