Cooler Bypass Delete 14-18 GM 6L80

The BD DIESEL Cooler Bypass Delete for 14–18 GM 6L80 is designed for transmission builders and performance diesel enthusiasts who need improved thermal management for their Chevy or GMC trucks. This bypass delete kit eliminates the factory transmission cooler circuit, allowing for independent management of transmission fluid temperature through an auxiliary cooler setup.

By blocking the stock transmission cooler return path, this component prevents fluid from cycling through the engine oil cooler, reducing parasitic heat exchange. The kit is made from durable aluminum and weighs approximately 2 lbs, integrating seamlessly into the transmission's cooling circuit without adding significant bulk.

Ideal for those running modified 6L80 transmissions, this cooler bypass delete is particularly beneficial for trucks that tow, haul, or undergo competitive tuning. Mechanics and transmission tuners favor this product for its ability to enhance thermal control and improve the longevity of the transmission.
