The Mishimoto MMTC-F2D-99SL replaces the factory unit with a 37-row stacked-plate core that increases core volume by 265% and adds roughly one quart of transmission fluid capacity. That extra capacity and surface area deliver a verified temperature drop of more than 10°F (5.6°C) while maintaining normal fluid pressure, helping your transmission run cooler under load.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cooler improve transmission temperatures during towing?\u003c\/h3\u003e\n\u003cp\u003eThe Mishimoto cooler increases heat rejection by expanding core surface area and fluid volume, letting the transmission shed heat faster when the truck is working hard. Improved cooling reduces the frequency and magnitude of temperature spikes, which helps preserve fluid life and component durability.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e37-row stacked-plate core for greater heat exchange\u003c\/li\u003e\n  \u003cli\u003e265% larger core volume versus OEM\u003c\/li\u003e\n  \u003cli\u003eVerified \u0026gt;10°F (5.6°C) reduction in operating temperature\u003c\/li\u003e\n  \u003cli\u003eExtra 1.0 qt fluid capacity to buffer heat under load\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill installing the Mishimoto cooler require modifications or extra parts?\u003c\/h3\u003e\n\u003cp\u003eThe MMTC-F2D-99SL is designed as a direct replacement for the factory cooler on 1999–2003 7.3L Powerstroke models, so no custom brackets or additional plumbing are required.
