The Jeep Wrangler JK is a definitive icon of off-road prowess, but to truly harness its potential, it’s essential to address the maintenance of its drivetrain heart—the transmission. Whether you’re navigating urban landscapes or exploring rugged terrains, ensuring your transmission fluid remains cool is paramount to performance and longevity. This is where the Mishimoto Transmission Coolers step in, offering a refined solution to some of the OEM system's limitations.

The stock system employs a thermostatic bypass valve regulating fluid flow to the cooler, only engaging at optimal operating temperatures to prevent overcooling. This precaution, however, can become a liability if the thermostat fails, leading to overheating—a serious predicament for any Jeep enthusiast. Particularly in hot climates, this restriction becomes redundant, creating unnecessary flow impedance. Mishimoto’s expertly engineered solution addresses these concerns with an innovative design specifically for the 2012-2018 Jeep Wrangler.

The Mishimoto Full-Flow Thermostatic Bypass Valve Kit stands out with its robust all-aluminum CNC-machined housing, effectively replacing the prone-to-failure stock unit. This advanced full-flow construction ensures that fluid circulates unimpeded through the cooler from the moment your Jeep starts. It’s an upgrade that not only eliminates the weak link of the usual bypass but also significantly enhances thermal management, particularly valuable in extreme driving conditions or when towing substantial loads.
