MMX Performance DCT Transmission Oil Cooler - BMW M3 (E9x) 2008-2013
Lease for as low as $/week
The MMX Performance BMW E9X M3 DCT Transmission Oil Cooler is a direct upgrade for one of the most temperature-sensitive components on the E9X M3 platform. The factory DCT cooler is adequate for stock-power, mild-driving use, but the moment the car sees track time, hot weather, traffic, or any meaningful tune (particularly forced induction) gearbox oil temperatures climb quickly, and a hot DCT is a slow DCT and, eventually, a damaged one.
This MMX cooler replaces the OE unit with a substantially higher-capacity core that meaningfully extends the thermal headroom of the gearbox. The result is more consistent shifts under load, less risk of clutch-pack overheating, and a measurably longer service life for one of the most expensive components on the car. The cooler is engineered specifically for the E9X M3's DCT mounting points and oil routing, it's a direct fit, not an adapted universal core.
The benefit is most obvious on supercharged or otherwise tuned E9X M3s, where peak gearbox oil temperatures are routinely a real-world reliability concern. But even a factory-spec M3 driven hard on a hot day will see a clear, sustained reduction in transmission oil temperature with this cooler fitted, the difference between catching a problem early and finding out the hard way.
For any E9X M3 owner who tracks the car, who is running a forced-induction tune, or who simply wants to give the DCT every chance to live a long life, this is one of the highest-impact thermal upgrades available for the platform.
