The BD Diesel cooler bypass delete kit for 2014–2018 GM vehicles with the 6L80 transmission replaces the factory bypass valve and keeps the transmission cooler operational at all times. Removing the failure-prone bypass prevents debris from jamming the internal valve and reduces the risk of elevated transmission temperatures. The kit includes all new seals and a magnetic service plug to restore full cooler flow.
