BD Diesel 1061532 Transmission Cooler Bypass Delete Kit - Allison 2017-2019 Silverado Sierra

The BD Diesel 1061532 Transmission Cooler Bypass Delete Kit is designed to eliminate a critical failure point in 2017-2019 Chevrolet Silverado and GMC Sierra trucks equipped with Allison transmissions. Debris in the stock cooler bypass valve can cause the internal valve to jam in recirculation mode, preventing transmission fluid from flowing through the external cooler. This leads to rapidly rising transmission temperatures, potential overheating, and premature transmission failure.

Key Features:

• Completely eliminates the factory bypass valve assembly
• Ensures 100% transmission fluid flow through the external cooler at all times
• Maintains optimal transmission temperatures under all driving conditions
• Includes complete replacement block, not just a simple plug
• All new OEM-quality seals included for proper installation
• Replaces OEM part number 23413140

Installation & Warranty:

• Approximate install time: 1 hour
• Warranty coverage: 12 months or 24,000 miles on parts

Emissions Compliance: This product does not require a California EO number. By nature of its design as a replacement part, it is legal for sale and use in all 50 states.

By keeping the transmission cooler operational at all times, this bypass delete kit provides essential protection for your Allison transmission, particularly during towing, hauling, or other high-demand driving conditions where temperature management is critical.
