Treat Your Transmission. 6.0L Powerstroke Transmission Cooler R&D, Part 1: Factory Cooler Options
Yes, that's right, we are not quite done with product development for the 6.0L Powerstroke. Although these trucks are getting older, our team is finding more and more ways to enhance and improve them.
The factory-equipped 6.0 transmission cooler is relatively stout. In fact, swapping this cooler into the 7.3L is a pretty common upgrade. That said, we think we can provide even greater cooling efficiency and offer an upgrade for 6.0L and 7.3L trucks that tow heavy loads.
Factory Cooler Options
From 2003 to 2007, the 6.0L came from the factory with two different cooler options, a 26-row cooler and a 31-row cooler. Mounting and line connections were similar on both.
Our shop truck came equipped with the 26-row unit, so we ordered the 31-unit cooler as well for data collection.
Although one cooler is taller, they have the same thickness, as shown below.
Increasing the surface area and the internal capacity of the heat exchanger will improve cooling efficiency. We will also be making some adjustments to the external fins on the heat exchanger. Fins play a huge role in heat transfer, as they connect directly to the fluid tubes and transfer heat from the tubes to the air passing through the core. By creating more contact points, we can improve heat transfer. We achieved this by reducing the height of the fins and designing a tighter pitch, which make the fins denser.
Check out the cooler fins of the factory 6.0L transmission shown below.
This area of the cooler can definitely be improved.
Initial Data Collection
Before designing our counterpart, we needed to collect some dimensional data from the two factory transmission coolers. Each one was set up on our CMM (coordinate measuring machine) so we could gather accurate data.
Coming Up - First Prototype
Once our engineering team completes the design of our 6.0L transmission cooler prototype, we will be working up a unit to test on our truck! Stay tuned for a look at our first unit.
