Stacked-plate heat exchangers have long been considered the most effective type of oil or transmission coolers, primarily because of their increased surface area. Allowing fluid to spread out over this larger surface area decreases the time required for heat transfer to take place. As a result, plate coolers typically manage to cool a greater volume of fluid faster than tube-and-fin, or even plate-and-fin, varieties. Add to that a powerful tornado fan that ensures optimum airflow at all times, no matter the environment, and you have a super-efficient heat-exchange unit.

- Troubleshooting High Transmission Temperatures after Transmission Cooler Installation
- I would try reversing the direction of the fan on the Derale Transmission Cooler # D15960 that you have installed on your 1994 GMC Truck to see if that will yield you cooler oil temperatures.
Generally speaking coolers loose from 25 to 40 percent of their cooling efficiency when the fan pushes air through the cooler as opposed to being pulled through it. Also, depending on the location of the cooler in relation to underside of your vehicle the fan might be fighting the natural airflow directi
