Trans Cooler Install

Thank you for the photos Scott, helps out a bunch to show what you did.
AWD or RWD? What size stall? I'm doing a stall and other work this fall and have the brake duct kit now and need to know if I need to plan bigger.

you can one and done it with a trucool 40k. But you could also run a secondary cooler in your other duct.
Just make sure you use quality lines as dual coolers introduces more points of failure. A nice AN setup with braided line that support at least 250deg or more. Most rubber lines are in the 220 range or so and you have to look far and wide for higher rated temp lines
Doing a stall and internal mods this fall so looks like I'll have a brake duct cooler for sale soon.

I am going to a 40k running solo with braided lines and AN fittings from the trans. Keep things less "involved" and less failure areas.
I have a 3200 stall and am now RWD (was AWD). I have never seen good enough temps even in cooler weather (even slow dropping temps in colder weather once on highway). Running through the Rockies last year was not good on my nerves lol.

Not try to start anything here, but you can't use ports pointed down. It's only filling up maybe a quarter of the capacity, not effectively exchanging heat.. I'd bet a million dollars that trans will run cooler with ports pointed up.. This seems to be a very big mistake that a lot of tbss owners are making.40k trans cooler fits in front of the radiator with only minor trimming of the black core and a slight bend in the center hood support.![]()

Again, just trying to provide correct info for the community

The fluid will follow the path of least restriction, The easiest flow path for the fluid is to first fill the cavity not through the core. It will fill the end tank first, then move through the core. Some may move through the core during this, but it will displace air first.
Most OE heat exchangers be it trans fluid, power steering fluid..etc.. will have the fittings on the bottom.

#Iamnotwrong Go ask any professional race team how they orient ports on coolers... Moreover show me one example of an OE cooler with ports on the bottom. The hose itself is the least restriction, the cooler is the most restricted. I stand firm that the cooler will not fill up all the way with ports on the bottom... It's called gravity!
Now go do some more research and you will once again find out that you spoke before checking your facts.

Go look at any late model GM truck in your apartment complex. Trans cooler fittings are on the bottom.
Your description of flow restriction solidifies my example of why it will fully fill with fluid...
BTW...I'm fully aware that "best practice" is to fill a heat exchanger from the bottom. However, it is not required and rarely commented on.
I work for a manufacturing company that powers nearly everything via hydraulics. They all require heat exchangers. Sometimes we can orient them with inlets down, sometimes not. Sometimes they are even horizontal. They are still fully effective.
By your firmly held logic the horizonal ones would be completely useless. However, reality and data say otherwise.

Ok, did more research myself. I stand half-way corrected. It actually all depends on the exact design.. These 2 manufacturer's links give 2 different orientation instructions. The trucool literature explains how their design allows for both ports to be on the bottom. Of note though, is that a trucool engineer just told me 1. that any cooler's ports mounted above or below height of trans itself (whether ports on bottom or top) will result in slightly less flow and 2. that while trucools can be mounted in any position, ports on the bottom will fill cooler to 90%, while on top ensures 100%. Technically, I was right in that ports on bottom will not fill 100%
@Burnit- I appreciate your professional last 2 responses, but I don't live in an apartment (not that there is anything wrong with that)
We are both correct on ports being on top is "best practice"
It's not surprising that 90% is good enough for OE, apparently that platform must use a cooler very similar in internal design to Trucool

My '04 DMAX has the ports on the bottom as pictured above. I swapped it to a larger unit in the OE position though. I would commonly tow pretty heavy, my trans is heavily built with a 3 disk billet convertor. It also makes about 600hp to the wheel, and I live in Phoenix. Cooling systems need all the help they can get.
I also run a very large oil cooler, holds nearly a gallon with the lines. If you truly want to manage your engines operating temperatures, you must monitor oil temps.
One of the machines I build is on a F550 chassis. We pull a little over 200hp from the engine with PTOs and hydraulics. All while basically sitting still. In Ford's PTO logic it will turn off all PTO functions when the oil hits 275*, even if the coolant temps are in check.
