Change your BMW selection
Expert's advice:
"Keep your 2019+ BMW M340i (G20)/Z4 (G29) 3.0L shifting with the Mishimoto Automatic Transmission cooler. Even with the latest transmission technology, the age-old enemy to sports cars remains heat. While the tag team at Toyota and BMW already fitted the 2019+ BMW M340i /Z4 with an external liquid-to-air transmission cooler, heavy demand can still be too much.
With plenty of room to grow, Mishimoto expanded the transmission cooler's core, increasing the volume by 162% and the external fin surface area by 412% while retaining similar fluid pressures within the system. They also incorporated internal cooling fins to maximize cooling power to maintain proper transmission temperatures, perfect for long days at the track or a spirited drive through the backroads.
The Mishimoto Automatic Transmission Cooler for your 2019+ BMW M340i (G20)/Z4 (G29) 3.0L accomplishes all of this with a lightweight, aluminum tube-and-fin core, powder-coated in a sleek silver finish. As with all of their products, this transmission cooler also includes the Mishimoto Lifetime Warranty for a worry-free installation.“
