Keep your gears cool with the Mishimoto DCT Transmission Cooler for the 2015-2020 BMW. Extreme heat being applied to your transmission, however, can easily knock your M down a few pegs. Our cooler aims to provide your M with the cooling to keep up on the street and track. We started from the ground up for our DCT cooler design, equipping it with a new 1.25" thick core resulting in a 46% increase in core volume and 69% bump in external fin surface area. we also updated this core with a dual-pass flow and internal fins for improved heat transfer. Combined, our upgraded features improve the heat rejection characteristics for better heat regulation of the DCT in your M2 Competition, M3, or M4.
