Sometimes there are products we can’t wait to get on the market. The sense of urgency follows positive feedback after a release or hinting at a recently started project. There’s pride in giving people what they want, what they need. When our 2003-2007 6.0L Powerstroke Transmission Cooler Kit was released, the question that kept coming was if it would fit the 7.3L. What followed was a “no, sorry.” That didn’t sit well with us. The efforts grew exponentially as more questions surfaced about fitment, and as the number of requests to make a direct fit kit increased.

In retrospect, it would have been best to provide all you 7.3L owners with upgraded cooling when the transmission cooler first launched. The reason why our 6.0L kit wasn’t on option then was due to the hose routing. The lines are different. The 6.0L already has hoses that can adapt to our cooler without the necessity of lines from us. The inlets and outlets are in different spots here, so we needed to carefully design hoses that would properly fit the 7.3L. The cooler is the exact same, so the hardware is what needed to change in this kit to make it a direct fit.

As most of you Powerstroke-heads know, the factory transmission cooler in these older trucks are swapped out in favor of the 26-row or 31-row 6.0L transmission coolers. We only tested our current cooler design against the bigger 31-row cooler to confirm that we are doing all we can to improve the cooling these transmissions need. Our 37-row, stacked plate cooler achieved a 10–12°F improvement over the 6.0L cooler. Fluid pressure showed an improvement, too, with a maximum drop of 0.5 psi. All of this is due largely in part to the increased fluid volume, which increased by 21% above the factory unit. We have a full write-up on the testing conditions and data for you to look at.

We didn’t perform the same testing for this cooler on a 7.3L Powerstroke, but our core is almost 2.5 times the size of the stock 7.3L cooler with nearly triple the rows. We also already proved that it out-performs even the 31-row the 6.0L cooler. Whether you’re off-roading, towing the racecar or race-bike to the next track day, taking a scenic drive up some steep inclines, or working another day on the job, this cooler will ensure your transmission stays happy.

    1. Awesome! Be sure you place a presale order now though, you won’t be able to find it anywhere cheaper once the presale period ends! Click on the PRESALE link in the above post!

  1. Right on! Was contemplating retro-fitting the 6.0 cooler to my ’01 7.3 but no need for that now. Great job, Mishimoto. I will be ordering one when available.

    1. Great timing I’d say! It’s available to order during our presale right now! Just click on the link above to get to the product page and place your order. Once it is officially released and stocked in our warehouse, the presale price will no longer be valid and it will go to the MSRP price. Act fast!

      1. Got mine through riffraff on Mon 5/15. Immediately opened to find that the package did not include hoses or clamps. Contacted Clay who said they were on it but as of now have still not received any updates. Pretty disappointed as this is my daily driver and I need this installed yesterday.
