Mishimoto Transmission Cooler Thermal Bypass Valve for 2019–2025 Ram 2500/3500 6.7L Cummins
The Mishimoto MMTC-RAM2-TBV thermal bypass valve eliminates the factory transmission warmer circuit on 2019–2025 Ram 2500/3500 trucks equipped with 6.7L Cummins diesel and 68RFE or Aisin AS69RC transmissions. It directs 100% of fluid flow through the external cooler to achieve lower transmission temperatures during towing, hauling, or hot conditions. This upgrade replaces the restrictive factory plastic valve that delays cooling until 180°F, reducing wear and extending transmission life.
Key Features
- Full Flow to External Cooler: Bypasses factory warmer circuit for immediate 100% fluid flow to cooler, preventing heat buildup in high-load scenarios
- ATF Temperature Reduction: Lowers transmission fluid temps by 20–40°F under towing or heavy loads, improving shift quality and longevity
- Billet 6061 Aluminum Construction: CNC-machined with integrated 180°F thermostat and black anodized finish for durability and corrosion resistance
- Direct Drop-In Fit: Replaces factory valve using stock seals and mounting points with no modifications required
