Foreign Auto SupplyTransmission Cooler

Design• Extruded 6063-T6 body• Fully machined features• Proprietary 6063-T6 FAS thermal CORE• *Friction Stir Welded (FSW) lid for maximum

heat transfer • Retains stock hardware and placement

* Friction Stir Welding is a patented technology only available through a licensed supplier.

Comparison

FAS Oil to Air• 160 sq in Al. to Air area• 440 sq in Oil to Al. area

Stock VW Oil to Water• 40 sq in Alum. to Air area• 112 sq in Oil to Al. area

Advantages• Reduced thermal load on the engine coolant

system• 4 times the amount of contact surface area for

both oil and air over stock• Eliminates the possibility of intermixing coolant

and ATF as with previous design• Easier installation with the removal of cooling

lines

• Thermal loading shown under natural convection

Thermal Analysis

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 3rd gear for 40 min.
