Mishimoto Automatic Transmission Cooler

2020–2022 Toyota GR Supra 3.0L

MMTC-SUP-20

Overview:

The Mishimoto Automatic Transmission Cooler is engineered specifically for the 2020 to 2022 Toyota GR Supra 3.0L, designed to enhance the durability and performance of your vehicle’s transmission system. While the Supra’s advanced ZF 8HP automatic transmission delivers smooth and responsive shifts, intense driving conditions such as track days or spirited backroad runs can generate excessive heat, threatening transmission longevity and performance.

This cooler addresses that challenge by significantly improving heat dissipation, ensuring your transmission fluid stays within optimal temperature ranges. By upgrading the factory cooling system, Mishimoto helps maintain consistent shifting quality and reduces the risk of transmission overheating, making it an essential upgrade for enthusiasts who demand reliability under pressure.

Key Features:

Designed with precision and performance in mind, the Mishimoto Automatic Transmission Cooler offers substantial improvements over the stock unit:

• 162% increase in core volume for enhanced fluid capacity and cooling efficiency
• 412% increase in external fin surface area to maximize heat dissipation
• Incorporation of internal cooling fins to further boost thermal transfer
• Lightweight aluminum tube-and-fin core construction for optimal strength-to-weight ratio
• Powder-coated silver finish for corrosion resistance and a sleek appearance
• Maintains similar fluid pressures within the transmission system to ensure compatibility
• Direct fitment for 2020–2022 Toyota GR Supra 3.0L models, requiring no modifications
• Backed by the Mishimoto Lifetime Warranty for peace of mind

Construction & Design:

The cooler features a robust aluminum tube-and-fin core that balances durability with lightweight design. Aluminum’s excellent thermal conductivity allows rapid heat transfer away from the transmission fluid, while the expanded core volume and fin surface area dramatically increase cooling capacity. Internal cooling fins are strategically integrated to maximize fluid exposure to cooling surfaces, enhancing efficiency without compromising fluid flow or pressure.

The entire assembly is finished with a durable powder-coated silver surface that resists corrosion and complements the engine bay’s aesthetics. This thoughtful engineering ensures long-lasting performance even under demanding driving conditions.

Installation & Fitment:

Installation is straightforward with direct bolt-on fitment for the 2020 through 2022 Toyota GR Supra 3.0L. The cooler is designed to integrate seamlessly with the factory transmission cooling lines, requiring no custom modifications or additional adapters. Enthusiasts can expect a hassle-free upgrade that improves transmission reliability and thermal management without compromising factory warranties.

What's Included:

• Mishimoto Automatic Transmission Cooler core
• Pre-installed fittings and mounting hardware
