When I had my radiator built (PRC Custome Radiator) I intentionally did not put a transmission cooler in it, with plans to add an exterior cooler. After doing some research I determined that I would need a unit with a cooling fan if the cooler wasn't mounted in front of the radiator. I was trying to cut down on the number of cores that air had to pass to get to the engine/radiator and there was already a big ole honkin' A/C condenser in front.
My research led me to Derale Products (www.derale.com) and their 13960 fan assisted cooler. This is a 25 Row Hyper-Cool Remote Transmission Cooler Kit, with -6AN fittings. It comes with everything you need for a standard installation with the exception of fittings for the transmission. Ford c-6 transmissions use a input and output fitting that is 1/8" NPS which is a straight thread (as compared to tapered thread NPT) I'm told that you can use NPT fttings but my luck it would strip out or crack the case or some other problem that would cost $$$$$ (large dollars) .The NPS fittings are a little hard to find but most of the online tube suppliers can get them for you.
Let's start with the cooler mounting first...

In a standard install you just use the barb fittings and the rubber hoses to put the cooler inline with the radiator cooler and find a place to mount it and it's a little different if you don't use or don't have the cooler in the radiator.
My first chore was finding a place to mount the cooler unit that was as far from a heat source as possible and protected from damage and easy to plumb. I also had to consider mounting the filter assembly in proximity to the cooler... so keep that in mind if you're using a filter also. Fortunately I found room to the right and next to the tail shaft of the transmission. (and I had room in front of it for the filter assembly. )
I added a short section of 1" x 1/4" flat bar between the transmission rear mount and a crossmember......and mounted the cooler between the frame rail and this bar. I used 1/4" hardware and nyloc nuts... your cooler, your choice. It is mounted over the exhaust pipe but it's 3-4" above it and the fan will be blowing down and not sucking in the heat. By reversing the wiring to the fan you can reverse the flow... I'll be wiring to push the cooler air from the top of the filter down thru it... avoiding pulling the hot air from around the exhaust pipe.
NOW....let's mount the transmission filter.....
The filter inside the transmission pan on a c-6 is really just a can made of large mesh screen... it'll catch the big chunks. Probably do all that's required but I'm a belt AND suspenders kind of guy and figured it's a small investment in a large money project... so do all you can to eliminate problems from the start. This is a freshly rebuilt transmission and should be spanking clean... I want to keep it that way as long as possible. The filter I chose was a Wix product (my favorite) and traps down to 10-20 micron at a 7-9 gpm flow rate. more on the filter below...
My initial idea was to mount the filter vertically right in front of the cooler so lines wouldn't be long and complicated. That plan didn't work just right... too close to exhaust pipe. So I rotated it 90 degrees and mounted it inside the frame rail...It makes it a little more difficult to change the filter being horizontal and a little more messy... but with the proper prep I can handle the mess.... you can see in the pic below it's well above the pipe.
The original filter I bought was a Wix 51269 but after some advice from a guru he told me it didn't have a anti flowback valve so I researched and found a 51622. A longer filter with the valve... and it gives me a little more filter media. (size does matter)
I mounted the the filter housing against the inside of the passenger frame rail with 1/4 hardware w/nyloc nuts... the mounting holes are actually inside the running board brace.
here's a shot of the whole thing....
So by now you see that I didn't use barb fittings and hose... I opted for SS braided hose and AN-6 fittings.. spoiler alert... prepare to spend some money here... this stuff ain't cheap. I know no one will probably ever see it but it goes with the theme of the truck... and it's stronger/better. There are eight fittings involved (well, ten counting the transmission fittings) and they might be the same or different for you depending on your mounting and hose routing. Another nice part is it does away with screw clamps... I hate those things. The -6AN hose runs 4-7 bucks a foot depending on vendor and the fittings are 3-12 bucks each again depending on vendor. Ebay is cheaper than local shops, but I like to keep the local guy in business so most of mine came from a local performance shop.
Editorial note... IF you use braided hose.. this stuff will eat you... well maybe not eat you but will puncture you so badly you won't hold air... I strongly suggest you buy a Koultool (www.koultool.com) It's a slick little plastic tool that helps you stick the braided hoses in the fittings... really it's handier than a shirt pocket You can buy a single for about 30.. the kit below for around 75 or a professional model for 150... most of my hose is -6 so I only bought that one and it's saved the ends of my fingers much grief and pain. One stick from the braid will hurt approximately 45 minutes plus you get blood on the braid. If you're plumbing the whole car/truck with SS braid it's a good investment. Check out their page. There's also a cool video on how the tool works.
The rest is just plumbing. The output from the transmission is normally the front fitting and the input is further back on the transmission... here's a picture to show you the fittings on a C-6
The route I chose (by suggestion from the guru and Derale's plans also) was out of transmission to filter.... out of filter to cooler.... out of cooler to transmission. And, maybe this picture will be clear enough to see it.
The last thing that you need to do is wire up the thermostat switch... instructions are in the Derale package and it's basically a 12 vdc on/off situation...
here's what Derale says.....
That's all it takes to be cool (well your fluid anyway) and clean... Think it will add some longevity to the transmission and that saves money. The only thing I might consider is a temp gauge for the transmission but right now I'm not seeing the need... I won't be towing... the the cooler should handle high temps. Talking to another builder about heat, he suggested wrapping the exhaust pipes with the titanium exhaust wrap (with LR technology). The LR tech is Lava Rock, which gives it higher temperature tolerance.. should cut down on radiated heat from the pipes under the cab. Looking into that now. If I do it it might prompt another article.
Boilerplate denial of liability statement… i.e. the fine print
The installation of this device is something I came up with to prevent me from spending too many dollars on a commercial install, it is not patented, engineered or even perfect… it is what it is, a home made installation. I’m sure there are alternatives to this way of doing things... some even better/cheaper/easier, I just didn’t think of them or warrant them necessary... there are several similar units on the internet waiting behind Google for you to see/copy/build…(just like I did) This work was done by me and for me or by friends who were nice enough to help me out. I only ask that if you reproduce it give me credit for it and if you make money from it… give me my percentage.
Since I have no way of knowing your level of competence, welding or cutting skills, mechanical ability or estimated intelligence, there are no guaranties or warranties either verbal, written or implied with this article. Along with this article I am giving you absolutely free of charge…that’s right ! FREE !!...the liability, total and complete liability for the use or misuse of these installation ideas will be yours and yours alone.
It belongs to you with that in mind… I am in no way responsible for any damage, injury or embarrassment you may suffer from the use of these ideas. If it doesn’t look like something you’d be comfortable using… don’t build/use it. If you’re not intelligent enough to make that decision about your comfort level… ask a family member or friend.. but here’s a hint… if you have to ask someone… don’t build it !
Pictures were made at different stages of construction and all assemblies in pictures may not be complete in each shot. I.e.. a picture showing ‘some parts’ only means that it was not finished, but I’ve tried to make the idea complete to the best of my ability. If you have questions or see mistakes or problems, let me know by e-mail and I’ll make the corrections if possible..
Use these ideas at your own risk. Modify them at your discretion and to suit your purpose. Your mileage may vary, batteries not included, much assembly required... wait one hour after building to enter the water, additional charges may apply. not all applicants will qualify for advertised A.P.R., for ages 10 to adult…side effects are comparable to placebos. Do not take drugs when building or operating machinery. JUST SAY NO.
