Boost your transmission performance with this PPE Bar and Plate Transmission Fluid Cooler. A bigger effective cooling area and thicker core enable the PPE cooler to draw 200% more heat from your transmission fluid compared to the factory cooler.  We observed up to 40°F temperature drop with a PPE cooler installed.

PPE Bar and Plate Transmission Coolers are made of high-quality aluminum, with specially engineered fin construction to maximize cooling efficiency while maintaining pressure drop as low as possible. It is a direct replacement with no modification or additional parts needed. Reuse factory cooler hardware for installation.

Product review

Message: I am an instructor for ACDelco ,I am also a former field service engineer for GM. I own a 2020 1500 silverado with an 8 speed trans. I purchased your cooler and flow control valve because when I tow the trans Temps would be between 220 and 245 degrees. I just took a 1500 mile trip with my trailer and never saw a temp higher than 220 degrees. Normally it was 180 degrees. I love your product and want to make sure others find out. I will be telling everyone I can.

Thanks for a great product.

Jerry
