The yellow GT is back in our R&D facility to show us a thing or two about testing trans coolers. Upon the GT's arrival, we wasted no time getting the pony car saddled with our testing rig.

We couldn't have asked for a better day for our Mustang transmission cooler testing. We began testing on a beautiful

In our last post, we took a look at the stock Mustang automatic transmission cooler and our plans to make it even better. We designed the cooler in Solidworks, based off the measurements obtained from both the GT and the stock cooler. We will be doing our R&D with this bold yellow GT, but based on our research, this cooler will fit all models of S550 Mustang including the EcoBoost and V6. But enough about fitments, the prototype is complete! It is time to see how well our digital design translated into a real-life prototype.

So far the trans cooler is looking good. It is much larger than the stock cooler, 50% larger to be exact. The stock cooler comes in at 10 rows, where the Mishimoto

Over the past year we have been getting acquainted with our Mustang GT, and in the process we've developed an entire line of cooling products for it. In the spirit of staying cool, we are on to our next project, the Mustang GT Automatic Transmission Cooler.

Heat is generally the enemy of an automatic transmission. In fact, the Ford factory service manual notes that when the GT's computer senses the transmission overheating, it will limit RPMs until the temperature returns to a normal range. There is nothing worse than a track day ending early due to high temps of any kind, including in the transmission. Whether you are taking your GT to the track or
