Replacement Transmission Oil Cooler

The Mishimoto Replacement Transmission Oil Cooler is engineered as a direct-fit solution for 2006-2018 BMW N20, N52, and N55 engines. This unit replaces the original liquid-to-liquid transmission oil cooler, which utilizes the engine's cooling system to regulate transmission fluid temperature, warming it in cold conditions and cooling it in warm temperatures. Failure of the factory cooler can lead to coolant contaminating the transmission fluid, potentially resulting in costly repairs or replacement. The Mishimoto cooler offers a reliable replacement, constructed from durable, corrosion-resistant aluminum. All factory lines and hardware can be utilized, and the cooler includes a gasket for a complete installation. The unit is backed by the Mishimoto Lifetime Warranty, providing peace of mind.
