Has anyone upgraded their trans cooler?

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
 
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:

SHO Performance Package

$1,300

Enhance the performance of your SHO with the available SHO Performance Package. It features:

• Upgraded performance brake pads
• Sport-calibrated electric power-assisted steering (EPAS)
• Higher-rated springs, tuned shocks, stiffer stabilizer bars and rear suspension to provide a more connected feel between the driver and the road
• Standard AdvanceTrac® electronic stability control (ESC) features a “Track Mode/True Off” setting that delivers a more spirited driving experience
• 3.16 final drive ratio for off-the-line acceleration
• 20” machined and painted wheels with performance summer tires*
• New larger front and rear brake rotors
• Upgraded cooling pack
• Tire mobility kit (in lieu of spare tire)
• Alcantara® suede-wrapped steering wheel

*Ford does not recommend using summer tires when temperatures drop to approximately 40°F or below (depending on tire wear and environmental conditions) or in snow/ice conditions. If the vehicle must be driven in these conditions, Ford recommends using all-season or snow tires.
 
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!
