How the Long Tru-Cool (LPD) Transmission Coolers Works:

(LPD) Low Pressure Drop Cooler

 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 is then directed through the core where it is cooled.  Tru-Cool’s highly efficient cooling technology combines improved protection against lube system failure with optimal heat transfer.

Long^® Auxiliary Stacked Plate and Plate/Fin Transmission Oil Coolers

The Long Tru Cool LPD Auxiliary Coolers are available in stack-plate design and in plate-and-fin design. The former features embossed plates that stack up and the latter employs fins between oil channels. These LPD Tru Cool, thick coolers come with the standard installation kit.

While the fin & plate design Long Tru Cool (LPD) Coolers, offer high heat transfer performance and low air-side pressure drop, the stack-plate coolers feature very high durability.  These coolers are installed on vehicle fronts for auxiliary cooling of passenger cars and light trucks. 

Long Transmission Cooler, standard installation kit will include

Long Tru Cool (LPD) Cooler, hose, fitting, and hardware for your installation.  These kit also contain two styles of mounting hardware, quick connect nylon straps and steel mounting for easy installation.  Each kit comes with complete mounting instructions for proper installation locations.
