Take engine coolant out of the equation on your 2017–2019 Ford 6.7L Powerstroke with the Mishimoto Heavy-Duty Transmission Cooler with OEM cooler bypass. The factory liquid-to-liquid cooler can only bring trans fluid down to coolant temperature; this kit bypasses it and sends fluid to a dedicated air-cooled core built for towing and hauling in hot weather.
Why Choose the Mishimoto 2017–2019 6.7L Powerstroke Transmission Cooler?
- Air-cooled, not coolant-limited – the included bypass eliminates the factory liquid-to-liquid cooler, so fluid temps no longer climb with engine coolant under load.
- Built for heavy towing in the heat – a dedicated tube-and-fin core sheds transmission heat straight into the airstream.
- Turbulated internal fins – keep fluid moving across more cooling surface for consistent temperatures pull after pull.
- Tough all-aluminum core – robust tube-and-fin construction stands up to sustained towing heat and constant thermal cycling.
- Hard lines included – application-specific fluid hard lines route to the new cooler for a secure, leak-free connection with no custom plumbing.
- Lifetime warranty – backed by the Mishimoto Lifetime Warranty.
