Description
The Mishimoto MMTC-DMAX-17SL is a silver-finished transmission cooler engineered specifically for Chevrolet and GMC trucks equipped with the 6.6L Duramax L5P engine. As part of the Mishimoto Cooling lineup, this transmission cooler is built to address the added heat load that comes with towing and heavy-duty driving in these L5P-equipped trucks.
A transmission cooler works by helping manage the temperature of transmission fluid, and heat is one of the primary contributors to transmission wear over time. For owners searching for a Mishimoto transmission cooler, Mishimoto trans cooler, or Mishimoto cooler solution for their Duramax-powered Chevrolet or GMC truck, the MMTC-DMAX-17SL is purpose-built for this exact application, giving these vehicles a dedicated cooling component rather than a generic, one-size-fits-all part.
Vehicle Applications

If your truck falls within this Chevrolet/GMC 6.6L Duramax L5P 2017-2019 range, this cooler is matched to that specific engine and model-year window.
