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 :thumb:
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!

Just an fyi, the transmission cooler (not aux) is actually part of the ac condenser radiator. It is the top ~4 inches so it has nothing to do with coolant. That makes me fairly confident that there is no noticable difference between having the straight portion of the Tee going to stock radiator vs aux or vice versa.

This is true of the 10-12 SHO's. If i'm not mistaken the 13+ cars do route the transmission fluid through the actual radiator rather than AC condenser. Just wanted to clarify.
I have a 13 SHO so I do think you may be mistaken.

whoops glanced right past that. i know radiator part #s are different between gen 4.1/4.2 because of an additional cooling system that runs through them. possibly PTU or oil cooler though.

Would also like to add that since I'm driving with the bumper off, i was able to verify which cooler was doing most of the work. Even though my aux cooler is on the branch of the tee, it was very hot to the touch, the cooler that is part of the AC condenser was basically cold.

FWIW i first changed the by-pass thermostat and months later added the aux cooler and have noticed virtually no temp drops since. seems to keep it from heating up as fast as it did before The cooler but still reaches the same peak temps.

I am glad you tried the bypass TStat and it worked out for you!

it helped. however i was hoping adding the aux cooler would keep the trans temps below 200* most days of the year and it's close but usually runs in the upper 190s and it's not that hot here yet. ideally i'd like to stick around 180ish. going to replace fluid with amsoil at some point and go from there.

Are you running Motorcraft in there right now?

Yes. 32k Oem fluid as of now so it's due for a change soon.

Based on my looking at trans temps, I can never get past 150 on the 30 minute drive to work. Highway heats it up more than city driving from what I have seen. 200 is pretty much the higher end of normal operating temp.

yeah i'm not sure why my results are seemingly different from what others with the aux cooler report. by no means does having 200* trans temps make me nervous or anything(before the t stat i saw 215-220) but 180ish is my preference.

Could it be an issue with the altitude you are at? Air density does drop 10% when "mile high". Maybe Yuma County (though still way above sea level) would be a different story?

That crossed my mind briefly but not sure how one would logically conclude that lower air density/altitude would cause fluid temps to rise(Then again i'm no physicist). I'm sure there could be some science to it but i've never experienced that in any previous platforms at the same altitude and if there were some correlation i would think it would be somewhat of a known fact in the automotive performance community up here.
Sho bro your altitude always makes me think about stuff...I remember seeing water boil at room temperature in a vacuum....higher pressure increases boiling point right?...so does your car in lower barometric pressure make it easier for temps to rise?
And i have your log i just dont want to hastily throw a revision at you...i have to think about things more with altitude...i also found out the barometric pressure sensor is part of the ecu..pretty cool
Try making the switch to Amsoil sooner than later. I have *heard* that it can keep transmissions running up to 20F cooler. I say make the switch, knowing that bpd has the same mods on his SHO basically, but uses the Motorcraft fluid on an annual swapout regimen with no issues. I am sure he can offer more insight.
Any chance these pictures could be refreshed? I have seen the post by @bpd1151 (https://www.ecoboostperformanceforum.com/index.php?action=profile;u=152) and @SHOdded (https://www.ecoboostperformanceforum.com/index.php?action=profile;u=60) / @SkookumFord (https://www.ecoboostperformanceforum.com/index.php?action=profile;u=161). I was hoping to see where @polskifacet (https://www.ecoboostperformanceforum.com/index.php?action=profile;u=1885) placed the stainless T. Also curious as to if it would be beneficial to run the Transmission fluid cooler outlet tube - Auxiliary transmission fluid cooler OTA - Transmission fluid cooler - Transmission fluid cooler inlet tube. This would keep the hottest fluid away from the condensor allowing it to work better.
@Ta2dResqr (https://www.ecoboostperformanceforum.com/index.php?action=profile;u=6260) if you want, you can tag other users to get their attention :) just use the @ symbol. IE.. @polskifacet (https://www.ecoboostperformanceforum.com/index.php?action=profile;u=1885)
Ill see what I can do

Does anyone have links to these members posts of transmission cooler setups? I can't seem to find them maybe I just don't know how thanks.
My SHO never had ACC.....
But here is my "How-To" on my install itself.
FWIW.....

I believe there was one write up at least from a member who had ACC, and I believe they essentially just moved the radar for the ACC itself.
