Mishimoto DCT Transmission Cooler, BMW S55

Keep your gears cool with the Mishimoto 2015-2020 BMW DCT Transmission Cooler. The F8X platform is one that demands peak performance, and the dual-clutch transmission equipped on your M2 Competition, M3, or M4 provides you with lightning-fast precision gear changes putting you in a league above the rest. Extreme heat being applied to your transmission, however, can easily knock your M down a few pegs. The Mishimoto transmission cooler aims to provide your M with the cooling to keep up on the street and track. Mishimoto started from the ground up for their DCT cooler design, equipping it with a new 1.25" thick core resulting in a 42-percent increase in core volume and 69-percent bump in external fin surface area. These improvements are more than just skin deep too, as Mishimoto updated this core with a dual-pass flow and internal fins for improved heat transfer. Combined, their upgraded features improve the heat rejection characteristics for better heat regulation of the DCT in your M
