      Maintain Proper Function. An overheating transmission can cause problems like slipping and decreased function. When left unchecked, this can result in more serious problems like damage to the transmission’s rubber components and even failure in the extreme. The Mishimoto Performance Transmission Cooler is designed to outperform your Gladiator’s stock transmission cooler, ensuring the ideal transmission function is maintained.

      Outstanding Tube and Fin Design. This transmission cooler utilizes the tried and true tube and fin core design similar to stock. What sets this component apart is its 195% increase in internal fin surface area as well as a 93% increase in external tube area over stock. These factors combined with an 83% increase in fluid capacity over stock translate to exceptional transmission cooling even in the most extreme driving conditions.

      Efficient Install Procedure. This transmission cooler is designed to install into your Gladiator’s factory cooler location without the need for modifications to your vehicle. Additionally, this assembly installs into your engine bay using a combination of the stock and included hardware for convenience.

      Backed by a Limited Lifetime Warranty. This Mishimoto transmission cooler is backed by a limited lifetime warranty covering manufacturing defects. Please visit the manufacturer’s website for more details.

      Application. The Mishimoto Performance Transmission Cooler fits all 2020 to 2022 Jeep Gladiator JT models.
