7.3L Powerstroke Transmission Cooler MMTC-F2D-99SL

Cross-references to MMTC-F2D-99SL and fits 1999-2003 Ford Powerstroke 7.3L trucks. Heat is what kills an automatic behind a diesel: tow a trailer up a grade in the summer and pan temperature climbs fast, the fluid oxidizes, and the clutch material starts glazing. Adding cooling capacity ahead of the radiator is the cheapest insurance you can put on a 4R100.

The kit ships with the cooler plus the hose and clamps needed to plumb it in, so you are not chasing fittings partway through the job. It mounts in the airflow ahead of the radiator and plumbs inline on the transmission cooler return line. Same cooler also works as an auxiliary cooler for engine oil or a rear differential if you are building a dedicated cooling circuit.

Measures 34.5 x 27.25 x 2.85 inches packaged and weighs 16.46 pounds, so check your available real estate in front of the radiator support before ordering. Machined aluminum construction.
