The Mishimoto 2021+ BMW G8X M2/M3/M4 Transmission Cooler is an upgraded transmission cooler designed to improve the performance of your BMW. 

The ZF 8-speed transmission integrated into the 2021+ BMW G8X M2/M3/M4 is a robust and responsive component that effortlessly manages the torque unleashed by the S58 engine it's paired with. Introduce tuning and bolt-on modifications, and the factory cooler struggles to maintain the ZF 8HP's stability. This deficiency may result in elevated transmission oil temperatures, sluggish gear shifts, and potential transmission strain. A solution emerges as the Mishimoto 2021+ BMW G8X M3/M4 Performance Transmission Cooler – a creation by the engineers at Mishimoto, dedicated to preserving optimal fluid temperatures and ensuring the ZF 8HP's peak performance.

Distinguished by its remarkable 41-percent enlargement in core volume, the Mishimoto 2021+ BMW G8X M3/M4 Performance Transmission Cooler delivers markedly superior cooling efficiency compared to its stock counterpart. This translates to sustained transmission coolness even during the most taxing driving conditions. Additionally, the transmission cooler offers a 17-percent augmentation in fluid capacity, heightening the entire system's cooling potential. Integrating internal cooling fins amplifies the surface area in direct contact with the fluid, enhancing heat transfer and overall efficiency. The dual-pass design prolongs fluid exposure within the cooler, leading to heightened heat removal without impeding the airflow to other cooling components positioned behind the transmission cooler.

On the track or the road, concerns extend beyond elevated fluid temperatures; the transmission cooler faces impacts from road debris as it occupies a prominent position in the grille. Recognizing this, a robust steel stone guard is incorporated, ensuring the safeguarding of the trans cooler and the retention of fluid within the designated space. Swift and straightforward installation is guaranteed, with no modifications required. As a testament to Mishimoto's commitment to quality, the Mishimoto 2021+ BMW G8X M3/M4 Automatic Transmission Cooler is covered by the renowned Mishimoto Lifetime Warranty, instilling peace of mind and confidence in your investment.
