2015-2019 GM 6.0L/ 6.2L 6L90 Transmission Cooler Bar & Plate (124064100)

Fits

The factory 6L90 cooler runs undersized for the job, and its air-blocking plastic mount makes the problem worse. PPE's bar-and-plate cooler is substantially larger, mounts without blocking airflow, and consistently maintains lower fluid temps where the factory unit falls short.

• Double the frontal area compared to the stock cooler
• 3.3 times larger core volume
• 40 degrees F transmission fluid temperature drop
• All-aluminum bar and plate construction
• Robust extruded-aluminum end tanks
• Comes with new transmission line fittings and mounting hardware
• Limited lifetime warranty

Excessive heat prematurely damages transmission components. The 6L90 transmission in the 2015-2019 Silverado/Sierra HD is prone to overheating due to flaws in the factory cooler design. With its air-blocking plastic mount and inadequate size, the factory cooler fails to maintain optimal transmission fluid temperatures.

Enter the PPE Performance Transmission Cooler: boasting a substantially larger frontal area for improved airflow, and a monstrous 3.3 times larger cooling core. This translates to a remarkable 350 percent increase in cooling capacity, resulting in a reduction of transmission fluid temperature by over 40 degrees F. Its robust extruded aluminum bar and plate construction ensure durability under all conditions.

Installation of the PPE Transmission Cooler is a breeze with its bolt-on design. All mounting hardware and brackets are included.
