Videos (1)
The Mishimoto MMTC-F2D-99SL is a 37-row transmission cooler for a 1999–2003 7.3 Powerstroke. It is the silver kit. It replaces the factory cooler in the stack.
The core is 6061 aluminum, about 25.25 by 16.13 by 1.25 inches. Mishimoto lists 265 percent more core volume than the factory 9-row cooler, about 1 quart more fluid, and a 10-degree drop in fluid temperature. Ports are 1/2 inch. It bolts in on the factory mounts. A truck with the power-steering cooler in the upper spot has to move that cooler down. A truck built before December 8, 1998 may need the brace checked. The warranty is lifetime.
It fits 1999–2003 F-250 and F-350 trucks with the 7.3.

Ran new coolant lines back to the tranny from the Mishimoto. This larger cooler should help the transmission last longer. It is twice the size of the stock one that came out of 7.3 L Powerstroke. It was one of the easier parts to install on this rebuild and it looks fantastic (see pics)

Nice quality product. Very well made. Fit perfect and tranny is running cooler than ever!

The cooler is huge.Welding and assembly is top notch as all Mishi products I have are.The hoese assemblys adapt from half inch to 3/8 and are a similar to the Aeroquip hose.Temps over 25 miles empty are noticeably lower as I just installed this morning.
