Airtec Motorsport DCT Transmission Coolers are designed to replace restrictive OE components and overcome excessive heat build-up in modern high-performance and tuned vehicles transmissions when driven hard.Maximum cooling for fast road and trackDual pass high-performance core25-35% more efficiency more than stockDual-clutch transmissions are subjected to extreme stresses and heat when combined with high-performance engines and demanding driving on the road or track. With Modern vehicles when stresses and heat build up your cars engine management will try to prevent damage to vital components by restricting performance or in the worst-case resort to limp mode.By installing an external transmission cooler, just like your coolant system's radiator, hot transmission fluid will effectively transfer heat into the coolers heat exchange matrix which rapidly cools as air passes through it. Airtec's transmission coolers use a compact dual-pass construction that increases both the core size and
