The Mishimoto transmission cooler for 1999–2013 Chevrolet Silverado and GMC Sierra uses a stacked-plate core with internal and louvered external fins, offering a core that’s substantially larger than stock (noted as a major increase in frontal area and volume). It includes precision -6ORB quick-disconnects, a relocation bracket for the ambient air sensor, and an adjustable mounting bracket for straightforward installation.
