BD Diesel | COOLER BYPASS DELETE ALLISON - Silverado / Sierra 2500 HD / 3500 HD 6.6L 2017-2019

BD Diesel – Allison Transmission Cooler Bypass Delete

Description

Debris in the stock cooler bypass valve can jam the internal valve in recirculation mode, preventing transmission fluid from reaching the cooler. This causes rising transmission temperatures, potentially leading to overheating and premature failure. The BD Cooler Bypass Delete (SKU 1061532) is designed for the Allison transmission in Duramax L5P trucks and replaces the failure-prone valve with a full replacement block — not just a plug — ensuring 100% fluid flow through the transmission cooler at all times. Includes all new seals required for installation.
