Mishimoto MMTC-F2D-11X Heavy-Duty Transmission Cooler, Natural Aluminum

The Mishimoto MMTC-F2D-11X Heavy-Duty Transmission Cooler is a direct-fit upgrade engineered to solve a fundamental weakness in the factory cooling setup on the 2011-2016 Ford 6.7L Powerstroke. The stock liquid-to-liquid design cools transmission fluid against engine coolant, which means fluid temperatures can never drop below coolant temperature — a ceiling that disappears quickly under the sustained load of towing in hot weather. This kit eliminates that limitation entirely: an included bypass component removes the factory liquid-to-liquid cooler from the equation and routes fluid to a dedicated air-cooled aluminum core, where the airstream handles heat rejection directly. The result is consistent transmission fluid temperatures under the loads that push the factory system past its limits.

Key Features:

• Replaces the factory liquid-to-liquid cooler with an air-cooled design — included bypass component eliminates the OE cooler so fluid temps no longer rise with engine coolant under towing and load
• 19-row tube-and-fin aluminum core sheds transmission heat directly into the airstream, rated for sustained towing duty and constant thermal cycling
• Turbulated internal fins keep fluid moving across more cooling surface area for stable, consistent temperatures pull after pull
• Application-specific fluid hard lines included — routes cleanly to the new cooler for a secure, leak-free connection with no custom fabrication or plumbing
• Complete kit includes: (1) transmission cooler, (1) direct-fit bracket set, (1) direct-fit hardware set, (1) direct-fit transmission line and adapter set
• Core dimensions: 30.3 in. wide × 7.87 in. tall × 1.26 in. thick; overall dimensions: 34.29 in. × 10.43 in. × 1.42 in.
• 1.7 qt. fluid capacity; 0.5 in. inlet and outlet diameter
• Natural aluminum finish; no electric fan
• Compatible with the TorqShift 6R140 transmission and P473 Super Duty chassis
• U.S. Patent D1,076,984S
• Backed by the Mishimoto Lifetime Warranty

Built to the performance-grade standards Mishimoto is known for, this transmission cooler is a clean, complete upgrade for 2011-2016 Ford 6.7L Powerstroke trucks — installed without fabrication using the included application-specific lines and hardware.
