128060110 | PPE Performance Heavy-Duty Cast Aluminum PTO Side Plate Cover For GM 6.6L Duramax | Brushed Finish

Made from cast aluminum, these covers add strength to center of the transmission case eliminating trans oil seepage at the mating surface.

Cooling fins double the surface area (60.74 sq. in.) when compared to stock (30.62 sq. in.), which increases heat dissipation from the transmission fluid.
