Advantages
Reduced thermal load on the engine coolant system4 times the amount of contact surface area for both oil and air over stockEliminates the possibility of intermixing coolant and ATF as with previous design
Easier installation with the removal of cooling linesSlide5

Thermal AnalysisSlide6
Testing
*Thermal bench testing has shown the cooler to operate between 175-188F without air flow.
*
Testing was conducted at 74F with a completely rebuilt transmission running fully synthetic ATF at full load in 3
rd
gear for 40 min
