8L90 Auxiliary Transmission Cooler Kit

Excessive heat is the number one contributor to transmission failures and can cause clutch pack slipping, clunky shifting, fluid breakdown, etc. Constant overheating can reduce the transmission life by 50% or more.

The 8-speed transmission paired with the 2.7L L3B turbocharged engine is prone to overheating, due to the lack of a dedicated front-mounted transmission cooler. The cooling of the 8L90 solely relies on a small heat exchanger that receives hot engine coolant, and the transmission temperature can easily reach 210°F just cruising around town.

Keep your transmission running cooler and lasting longer with the PPE Auxiliary Transmission Cooler Kit. Engineered as a high-efficiency replacement for the insufficient factory heat exchanger, this all-aluminum, front-mounted unit features a massive 231-cubic-inch core. The heavy-duty bar-and-plate construction delivers superior heat dissipation, dropping fluid temperatures by up to 50°F. Transform your L3B TurboMax into a true workhorse ready to handle the toughest towing and hauling demands.

Installation is easy and straightforward. The transmission lines are a combination of hard lines and SAE-grade, crimped-on hoses, and are pre-assembled for precise fitment. Cooler fittings, mounting brackets, and hardware are all provided to ensure a hassle-free experience.
