Fellow owners,

As all of you may be aware, one of the small short-cuts that Ford took with the GT is deciding not to include a transaxle cooler as an installed option. On the Ford Racing Parts website, Ford says the cooler is , "A must for aggressive driving and open track events." Further, you can tell that Ford was very close to having this as an installed option - even going so far as installing the fittings and a short length of braided steel hose "looping" the transaxle outlet to the inlet. Also, how many times have we heard about issues related to engine heat-soak as well as that pesky (leaky) breather valve on the transaxle. All of these annoyances are related to issues of heat and many are of the opinion that a transaxle cooler is a significant benefit and "safe insurance" to keep operating temperatures in check.

Currently, Ford Racing is the only game in town and several people have been very disappointed in what they have received. On May 20, "Indy GT" posted this message on the forums.

"I received the transaxle cooled kit from ford motor racing and am quite disappointed is has no install instructions whatsoever. A heat exchanger, line fitting assembly and bag of two AN fittings and 3 bolts. After waiting months for delivery (see previous backorder posts) this is not what I was expecting. Any help as to where to get installation instructions, and/or picture posts?"

To add insult to injury, Ford's cooler kit is priced at $1279. I'm not sure if all Ford Racing distributors pay the same, but one source told me his cost was $1180. So, it is doubtful that you can expect to get much of a discount. I suspect that kit cost and installation cost is what has caused many people to postpone a decision.

So, how about a great alternative that is an improvement over the Ford Racing option and which also costs less and is easier/less expensive to install?

I have just completed a complete custom kit for the GT and I am in-process to have kits put together and made available to the GT community.

The development criteria for a "better" custom GT transaxle cooler was as follows;

1. Functional. As good or better than Ford's alternative
2. Easy to Install. Give owners the option to install it themselves.
3. Aesthetically complementary to the GT engine compartment.
4. High quality lines, superior line routing and stays. (No wire ties!!)
5. The best quality components - Cooler, Lines, Fittings, Instructions
6. Absolutely NO drilling/cutting/tapping, or modification to the GT
7. A realistic price point.

Now that the kit is completed, I can say that we have met all of the design objectives.

In short, this kit employs a slightly larger cooler than the one offered by Ford and the bracket, lines and stand-offs have been designed to enhance the appearance of the engine compartment. The placement of the cooler is nearly identical to the Ford solution - utilizing incoming air from the passenger side air scoop.

Another benefit is that this kit can be installed by an owner with average mechanical skills. Unlike the Ford Racing Kit where you need to lift the car and remove the pans to properly fill the transaxle, this kit can be installed with no car lifting or pan removal! So, even if you're not a do-it-yourself-er, you can have this kit installed for a fraction of the cost.

The first 12 kits already have names on them from a pre-announcement I did with the California guys. These first kits will be available in approximately 10-14 days.

I've planned on batches of 20 units thereafter, and I can likely crank that number up or down depending on demand.

The initial price of the kit is $795 and it will be complete. (Shipping extra.) You will just need to add (<1 qt) Ford GT-Spec 75W-90 transaxle lubricant. As the stuff is hard to find and expensive, I may purchase some by the case and make it available as an option with the kit. (Stay tuned.) Speaking of options, the kit will include lines made from the latest and greatest Earl's Pro-Lite 350 which has an abrassive resistant nylon weave sheathing. These black braided lines not only match the existing lines in the GT, but they are also significantly lighter (and more expensive) than conventional stainless steel braided line. The fittings are also Earl's in the conventional blue/red annodize color as shown. You can tell me if you prefer all-black AN fittings and I can assemble the hoses accordingly.

So, please send me a PM or e-mail to let me know if you are intested to purchase this transaxle kit. Hearing from you will help me to gauge production rate so that I can hopefully meet everyone's expectations.

Here's a picture of the unit installed in my car. More pics to follow soon.

Looks like great work at a great price.

I have been pondering adding one, but I do not track my car at all. So the question is, has anyone installed a temp gage and checked the before and after on any of the transaxle coolers?

The price of this one is pretty sweet (esp for what you get) but it is still $800+ with shipping. Decent chunk of change if its not really needed for day-to-day street.

Just curious and tempted.

looks great,...but, I just bought the Ford Racing much more $$$ version. :eek

Same here... damn!! Looks sweet anyway...
 
I am interested, but would like to know what make and size of cooler you are using.
 
Is there a web site address for Ford Racing please
 
The Ford Racing Website

I would like to see some more picture of this set-up. I am definitely planning on buying a cooler and hate that fact that Ford is sticking it to us on these post production parts.
 
Nota4re - comparative

Nice looking desisn & packaging. Do you have comparative info vs. Ford Racing cooler - e.g. pressure drop, surface area, ID and OD of cooler input/output fittings and supply lines?

Thanx for the info.

Looks like a Setrab, top shelf cooler...clean installation.

Why not hard line it to the rear then use your braided stainless for a flex connection?
 
Yea, looks good, but I need more pics.

I too would like to see some more pictures.

*I also have a question. Is the main focus on trans cooler (for everyday driver not on track) just to keep temps low for longer use of trans with out problems? Or is there a plus to keeping temps lower in trans? ie shifting is better and/or smoother.
Thanks beforehand

Hello all,

Thanks for all of the looks and the good questions. I'll do my best to answer them to the best of my ability....

Unfortunately, I cannot find any data on Ford's cooler. All we have are the dimensions which are approximately 10" x 9". I consulted a lot with Setrab before we made the selection for the cooler in our kit. Setrab was one of the companies solicited by Ford to bid on the coolers (radiator, intercooler, transcooler, etc.) so they have familiarity with the GT. More importantly, Setrab has a lot of racing experience and, in particular with gear-oil based coolers. Setrab actuall believed that their model 619 cooler would be more than sufficient for the GT and on-par with the Ford cooler (Honeywell?). However, we discussed the fact that size would be a factor in people's decision making and some might believe that smaller means inferior. This fact as well as trhe fact that there was room to fit the larger, 625 model, led us to choose the 625 for this kit.

Regarding line size, we use a -8 AN throughout. Some DIY install have used -6 AN but with Setrab's input and knowing that the GT already has -8 AN adapters intstalled, we once again opted for "bigger is better". (Note: -8 AN = 8/16 = 1/2")

The Setrab 625 has a BTU/Hr rating of 16,000-27,000 for transmission/differential fluids. (The BTU ratings is much higher for engine oils but not applicable here.) Pressure drop, once again for trans/diff fluid is < 0.5 PSI.

It's main benifit will be to keep trans temp down and prevent oil degradation due to high heat on the track. On the street the extra cooling isn't needed but it isn't going to hurt. It's not going to make your shifting better or smoother.

Great question, Sandman. Actually, this is how it all started. Perhaps you recall seeing some early mock-up pictures I posted that was exactly like this.

We have several templates made and the appearance and "custom-ness" of custom-bent hard-lines is hard to argue with. However, there was a couple of reasons which eventually led us away form this alternative. First, and likely the biggest reason, is that we would be uncomfortable to bring a hard-line solution to market without significant testing. Strange things happen with vibrations and harmonic frequencies, etc. We weren't completely sure that hard-lines would have the longevity owners would expect. Secondly, we considered hard-lines with flex hose at each end to address the aforementioned fatigue concerns. We experimented with this but concluded that there were just too may joints. This added to the expense of a kit and to the number of potential failure points. Consider that the lines are only ~40 inches long in the first place.

So, what we came up with is this nice looking, albeit expensive, hard-line look by selecting clever mounting locations and by supplying trick hose seperators to keep the lines together and parallel. Obviously, we think this is the best solution and a good trade-off on appearance versus confidence in longevity.
 
I also have a question. Is the main focus on trans cooler (for everyday driver not on track) just to keep temps low for longer use of trans with out problems? Or is there a plus to keeping temps lower in trans? ie shifting is better and/or smoother.

Joe, the primary focus of the transaxle cooler is to keep trans temperatures in check when either driving aggressively or with track use. I suppose a second reason might be those people who routinely drive in hot weather - especially if they are occasionally driving the car like it was meant to be driven.

That said, my transaxle cooler kit or Ford's will have virtually no effect on tranny life or smoother shifting if you don't fall into one of the classes mentioned above. I suppose many people will select a Trans Cooler just to have the piece of mind if they do occasioanlly track the car and/or they want to occasionally (or frequently) drive it hard on the street.
 
I do drive in hot weather and do drive it like it sooooo begs so I am very interested in your cooler MR. nota4re. If you could send me some pics and/or post some more that would be great. Thanks again...

**** Transaxle Oil Warning ***

Those of you who are adding a transaxle cooler or who, unfortunately, have had the infamous halfshaft problem, will need to add add'l oil to the transaxle. Ford specifies a 75W90 weight full synthetic gear oil. I would highly recommend that you add exactly the oil Ford (Ricardo) designed for the GT. Frankly, when I did my cooler I was simply going to add some Mobil 1 full synthetic 75W90. However I discovered that Ford, despite already having 75W90 under the Motrorcraft label, went through the trouble of bringing ANOTHER GT-specific 75W90 gear oil to market. If you have work done at your dealer, make sure they use the right oil. The plastic quart containers are very similar and are shown below.

XT-75W90-QGT - This is the RIGHT part number for the Transaxle Oil

XY-75W90-QLS - is the WRONG oil for your transaxle.

As I understand, Ford will only sell this oil to a dealer by the case. No individual orders. Consequently, most dealers don't stock it.
