When it comes to Nissan 370Z and Infiniti G37 automatic transmission cooling, heat is the enemy. The Z1 Transmission Cooler Kit is engineered as a direct-fit upgraded transmission cooler for 370Z and G37, delivering increased cooling capacity and long-term reliability while eliminating the compromises found in typical universal cooler kits.

Built around our Z1 ProCooler stacked-plate core and paired with motorsports-grade plumbing, this system delivers consistent, reliable temperature control whether you're daily driving, canyon carving, or pushing a high-power forced-induction setup.

The Design

At the core of this system is a Z1 ProCooler, offering greater efficiency, improved heat dissipation, and durability under sustained load compared to traditional tube-and-fin coolers. The result is stable transmission temperatures where the factory system begins to fall short. Cores are available in one of three sizes, offering varying levels of performance to fit your budget and build.

Supporting that performance is a full motorsports-grade plumbing system. Stainless steel braided lines with AN swivel fittings are used throughout, routing directly to the transmission via banjo fittings for a secure, leak-resistant connection with consistent flow characteristics.

No rubber hoses. No worm clamps. No weak points. Just a purpose-built cooling solution designed to perform in real-world conditions, from daily driving to high-power forced induction and VR30-transmission swapped applications.
