I don't really like seeing my transmission temperature at 205 degrees on long trips.
Has anyone upgraded the stock cooler?
What did you use?
Haven't seen anyone do it on a Flex before. And not on 2013+ vehicles. But here are the HOW TO's we have to use te 2013+ SHO PP equipment:

Have you changed out the trans fluid at all since you bought the Flex? You can try upgrading the fluid to a better spec'd aftermarket brand. Shorter change intervals like 30,000 miles also would help significantly. If I am not mistaken, there is still a thermostatic device that controls when the trans fluid goes into the cooler. Maybe there is a lower temp aftermarket replacement? Do you have a colder TStat installed? With the tune, that should help cooling AND transmission systems.
And the old standby: are you sure the fins on the radiator/condenser are as clean as can be?

Why don't u like to see it at 205?...Just like oil the fluid doesn't even offer full protection until warmed up to operating temps...too cold is just as bad too hot.
There are a lot of old reliable transmissions out there that operated at 300...remember the dip sticks saying trans fluid can be 350?
Operating temp for these temps is between 175F & 200F IIRC from the owner's manual.

Do they spell it out that specifically in the manual?
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 180°F-200°F (82°C-93°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
This is from the 2013 SHO manual for the 6F50/6F55 transmissions. So yeah, I am inclined to go no higher than that spec.
Ok...then 205 sounds right on target...we are conditioned to believe that cooler is better but I don't think people are aware of drawbacks of over cooled fluids....I don't really want to get into it but at 205 I would have 0 concerns
Aiming for the middle of the N.O.T. range is a good idea, in this case 190F. The life of transmission fluid does not decrease linearly with increasing temperature. Hence the "normal" vs "severe" duty recommendations for maintenance intervals in the OM.
I replaced the trans fluid a few thousand miles ago with Motorcraft LV.
The temps remained the same.
I would like to see 190 on a normal basis.
Thermostat was changed to a 180 6 months ago.
You should call ford and tell them how stupid they are. I'm sure u can tell them the countless amount experiments and results u have found proving why 205 is so detrimental and the magic number of 190 that u have come up with is the much better idea lol
205 is frigid compared to the temps I saw with repeated 1/4 runs on the 2013.
My 2011 SHO runs 180 all day long. New ford fluid and Lubeguard auto transmission fluid protectant. Great stuff

Well now you guys have just pissed me off....I don't even know what my tranny temp is and now I'm curious so thanks for making me have to go out and log something else.

Now see, if you ran torque or dash command like I've suggested, you could just make a new gauge in about 1/2 second and have it handled.
I can tell you that PP with amsoil runs much cooler than non pp without.
Maybe I'll get some motivation one of these days and see how hot she gets at the track...
Like so...
Looks nice....Why can't we have that on our GPS screens?.....I don't have one of those fancy tablets and I'd hate to look at that on my phone

Because in Ford's infinite wisdom the equipped our 45k tech flagships with
composite video inputs.
Well I'm not a computer guy at all...We have Bluetooth...Can't you do a type of wireless or dongle or something from the OBD II port ...I'd run the composite cables to the screen if I could see all those gauges.

The problem is you need a Lockpick device to watch composite while driving.

Sweet!
So I just took the BBG out for a flogging to watch the trans temps....
Highest temp was 196 and this was a fairly extensive flogging....far worse that dragstrip days with the 2013 non pp that saw temps over 220
As soon as the flogging subsided temps dropped very quickly to the low 170's for normal cruising.
This is a 2015 pp that had a drain and fill with Amsoil at 150 miles.
YMMV
So there.
170 sounds good.
Is the cooler different in the SHO compared to the Flex?
FoMoCo has the 2015 Performance Package, his 2013 did not. The Flex has the same componentry as the non-Performance Package SHO.
How do the differences look (for 2010-12 anyway)? See the attachment in bpd's post here:

I suppose you could keep some cold ones in there, FoMoCo! ;)
Does Ford offer the aux trans cooler for the Flex?
You have a tranny cooler in your radiator. But it sounds like no matter what anyone tells you, you are going to want it to be cooler....Honestly, as long as you aren't exceeding the designed specifications, which it sounds like you are not, then I wouldn't worry about it.
You said you were about 205 at the highest...Well that's what your coolant is give or take so that makes complete sense. It sounds like you are right were ford wanted it...You plan on road racing that brick?
I agree that a high of 205 is not anything to panic about and would just do drain and fills every 30k miles or so.
For reference,the tranny cooler is actually the top section of the a/c condenser in front of the radiator on Flex, Taurus, Explorer, Edge, and their Lincoln counterparts.
Ford's specs are designed for vehicles that are unmodified. The more stress you put on the engine/powertrain, the more revisions you should expect to those specs. 205F for the trans fluid may be nothing to worry about IF that consists of a few spikes here & there (such as going WOT, being stuck in slowmoving traffic occasionally, etc) and temps generally stay in the 180-190F range otherwise. Since there is no cooling of the PTU in most instances, the less the heat transfer from the trans, the better, an indirect benefit. Obviously Ford knows the benefits (they don't tell us all their secrets ;) ), otherwise why would the PP exist? They have top-notch engineers. But what engineers can design and what they are allowed to design are hardly ever the same thing in a corporate context.
As far as coolant temps, ask Torrie why he recommends the 170F TStat for "hot" tunes, or LME why they recommend the even colder 160F TStat. Ask them what they see for normal cruising temps vs spikes.
We WANT the additive packages in the fluids to last as long as possible, no matter the interval we choose to R&R. The SAE specs used by mfr's seems like the USDA RDA for food. Minimum required to survive. But if you are an athlete, that RDA is nowhere near what you require to "survive". On top of that, you are going to pad your chances of survival by making sure your body is stocked as well as possible.

Just my 2 cents my 13 PP never goes over 95C (203 ish) even after repeated track runs around town it's always around 75C to 80C (175 ish) PTU is usually 10 degrees cooler than that other than at the track which is on par with trans temp.

True for me in winter, but not in PHX summers with ambients over the road approaching 130.
If I didn't have the aux transmission cooler in my other cars they would not have lasted so long.
It is amazing how quickly a quarter mile pass will heat up the fluid.

Lol your winter is my summer up here. We had a heat wave for the last 2 weeks and temps were only 40C (like 105F) with the humidity lol!

Does anyone know the part number for the lower temp transmission thermostat they run in the police interceptors?

I imagine its the same as the 13+ PP
Does anyone have a VIN to share with me that has the PP package with the factory trans cooler?
Here's one, culled from the great cesspool called EBay: 1FAHP2KT3FG205979. Or try this: 1FAHP2KT4DG177137
I will visit the dealer to see if they have different part numbers and what is available.
I doubt there are different ones...either you have a cooler or you don't but the stat for each would be the same

Correct.
Check my "How-To" for the part number.

Id say it's similar and super easy...was the aux cooler even available on the 10-12?
No, it was not available for the '10-'12 model years. At all. Didn't matter if it was PP equipped, or not.
I was the 1st to have retrofitted it, and the benefits therein are outlined in my "How-To".
Sent from my SM-N920V using Tapatalk
The PP retrofit is the cleanest route, but I remember the old days when we would slap on a B&M stacked plate cooler for under $100, definitely not $300+ in parts.
I increased the tcc lockup rate and reduced or eliminated desired slip, and saw trans fluid reductions of 10F up to 30F during our hottest summer days.
