Mishimoto R&D: 2017+ Raptor Performance Transmission Cooler

[Mishimoto]

Hey everybody,

Over the past several months, we've been developing a performance transmission cooler for the 2015-2017 F-150. As our development carried on, we discovered that our cooler would also fit the 2017+ Raptor. So, we wanted to share our development up to this point and let you know that we'll be having some more updates and a pre-sale soon! Check out the posts below and, as always, let us know what you think!

Looks like your mounting system covers the majority of the heat exchanger? Looks like everything you gained in added width is lost by covering the width.

That's just a mock up.

While our trans cooler will cover more of the heat exchangers behind it, it still takes up less than 1/4 of the radiator's surface area. Plus, compared to the solid plastic mount that blocks all airflow where it covers, our trans cooler will obviously have open fins that let air pass through. That air will be warmer than ambient, but that warmer air will have very little effect on coolant temps when applied to such a small area of the radiator and when compared to no airflow at all in parts that the stock bracket would cover. A more efficient trans cooler that reduces trans fluid temps also has the added benefit of taking thermal load off of the radiator - less of the coolant's thermal capacity is being used to cool the trans fluid and some of that capacity can then be used to cool the engine.

So, while we will blocking a small portion more of the radiator's surface area, the extra cooling provided by the trans cooler will be an overall benefit to both the trans cooling and engine cooling systems.

Feel free to let me know if you have any more questions! I should have more updates soon!

Does this cooler interfere with a front mount intercooler?

Does this cooler interfere with a front mount intercooler?

We haven't test-fit this with any aftermarket intercooler besides our own, so we can't guarantee fitment. However, just looking at images, I think you would probably be fine with Full Race's intercooler as we're not adding any thickness to the core of the trans cooler. It's iffy on if it will fit with Wagner's modified trans cooler mounts.

Feel free to let me know if you have any questions. I should have the final update on this trans cooler up today or tomorrow and our pre-sale will also be going up today or tomorrow!

Thanks!

Hey everybody,

We're excited to announce that our pre-sale for this transmission cooler is live and we have our final post outlining performance and fitment testing below. Check them both out, and let us know what you think!

Thanks,

Carry the Weight — Transmission Cooler R&D, Part 3: Production


​

The time had come to put our engineer’s hard work to the test, a bench test to be specific. The bench test determines if our final transmission cooler will be a stacked-plate or tube-and-fin design. Given the fact that our cooler is over double the size of the stock cooler, we’re confident that either construction will cool better, but the devil is in the details. Aside from the cooling performance of each construction method, we needed to consider the pressure drop across each. The cooling performance of the stacked-plate cooler might be better than a tube-and-fin cooler, but if the pressure drop is too high, it will all be for nothing. To settle the debate once and for all we set up our bench-test rig and got to work.

You may be wondering why we’re bench testing the coolers instead of road testing them. Road testing coolers is great for getting real world data when you can perform it on a closed course without traffic and with perfectly consistent weather. But, since we don’t have access to a closed course for testing and we’re no good at controlling the weather, we’ve opted for bench testing. Our bench test is designed to give us an apples-to-apples comparison between all three coolers. We can control the ambient air temperature in our shop, the airflow through the cooler with our dyno fan, and maintain a consistent fluid temperature and pressure. All that data can then be easily collected by our AEM AQ1 data-logger without having to worry about other parts of the vehicle’s cooling system interfering.

Thanks Steve!

You read my mind about the full race intercooler!

Whats the price? When is the radiator going to be done?

Hey @cwylie are you looking for the pricing of the radiator or the trans cooler? The pricing for the trans cooler can be found on our website: 2015-2017 Ford F-150 / 2017+ Ford Raptor Transmission Cooler Pre-Sale

The radiator that we're working on is still in R&D so we don't have pricing for it quite yet, but we plan to have that in pre-sale in about a month.

Thanks!
