About this product
Description
Excessive heat is the number one contributor to transmission failures and can cause clutch pack slipping, clunky shifting and fluid breakdown. The PPE 10L80 bar and plate transmission cooler gives your transmission the cooling it needs to stay healthier for longer.
The all-aluminum cooler has a 248 cubic-inch core, 3.25 times the volume of the stock cooler, and a 73% larger frontal area. Dense, louvered external fins help achieve a temperature drop of up to 45°F. The bar and plate construction is a heavy-duty upgrade over the factory stacked plate design, with greater cooling mass, flow capacity and pressure resistance.
Features
- 1x Trans cooler
- 1x Install guide
Notes
Note: For 3.0L Duramax applications, add PPE Thermostat Bypass Valve (SKU 125069000) for maximized cooling performance.
