Here's how Low Pressure Drop technology works to Protect Your Transmission:


When Automatic Transmission Fluid (ATF) is cold it is viscous.  

The unique Tru-Cool design allows the colder, thicker ATF to flow more efficiently through two open bypass channels positioned at the top of the cooler.  

As operating temperatures increase, the ATF becomes hotter and thinner,  It's then directed through the core where it is cooled.  

Tru-Cool's highly efficient cooling technology combines improved protection against lube failure with optimal heat transfer.


Long Tru-Cool Oil Coolers offer advanced cooling protection for car, van, light truck, R.V., and towing applications.


The advanced technology out performs TUBE & FIN designs: 

Delivering up to 15 times less flow restrictions

30% more cooling delivers maximum heat transfer

Self-Regulating for maximum lube flow protection through start-up

Varied temperatures and driving conditions, heavy loads and towing.
