Keep your dual-clutch transmission operating at controlled temperatures with the Mishimoto MMTC-F80-15 DCT Transmission Cooler. This automatic transmission oil cooler is designed to help regulate fluid temperature and reduce the risk of overheating during spirited street driving, track use, and other demanding conditions. It fits select 2015–2020 BMW F8X applications, including the M2, M3, and M4 models listed for this part. Please verify vehicle compatibility before installation.
The upgraded cooler core is designed to improve heat rejection compared with the original configuration. Its larger core volume provides a 42-percent increase, while the external fin surface area is increased by 69 percent to promote greater airflow contact. A dual-pass flow path directs transmission fluid through the cooler for more controlled heat exchange, and integrated internal fins add further cooling capability. These design improvements help maintain more consistent DCT fluid temperatures, support transmission performance, and promote longer fluid and component service life under demanding use.
