BD DIESEL 1061532 COOLER BYPASS DELETE FOR SILVERADO/SIERRA ALLISON 2017–2019

Product Description

The BD DIESEL 1061532 Cooler Bypass Delete eliminates the failure-prone factory cooler bypass valve from the Allison transmission found in 2017–2019 Chevrolet Silverado and GMC Sierra Duramax 6.6L trucks. The stock bypass valve can become jammed by debris, forcing the transmission into recirculation mode and causing higher fluid temperatures and reduced cooling efficiency.
