Mishimoto Enhanced Thermal Bypass Valve Kit for 2017+ GMC 6.6L Duramax L5P Transmission

Mishimoto Enhanced Thermal Bypass Valve Kit for 2017+ GMC 6.6L Duramax L5P Transmission

The Allison transmission is the backbone of your L5P Duramax, effectively transmitting large quantities of torque generated by your V8 diesel engine. However, this immense torque can produce significant heat, which, if not managed properly, could lead to transmission failure. While the transmission cooler works to maintain fluid temperatures, it can only do so if the fluid is allowed to flow correctly.

Key Features:

• CNC-Machined Aluminum Design: Not only enhances appearance but also improves functionality over the stock unit.
• Serviceable Thermostat: Ensures quick warm-up in cold climates for optimal transmission operation.
• Thermostat Bypass Option: Provides continuous cooling for hot climates or extreme driving and towing conditions.
• Improved Flow: Strategically machined internal passages allow for more effective cooling compared to the stock valve.
• Heat Dissipation: Cooling fins machined into the valve body enhance heat dissipation capabilities.
• Built to Last: Durable black anodized finish ensures longevity, backed by the Mishimoto Lifetime Warranty.
