Keep your automatic transmission fluid running cooler with the Hayden Rapid-Cool Transmission Oil Cooler (P/N 676). This aluminum auxiliary cooler adds heat-shedding capacity for many vehicles, among them the 1988-1999 Chevrolet C1500 [V8-5.7L] and 1999-2003 Chevrolet Silverado 1500 [V8-5.3L]. See the Buyer's Guide tab for the full list of vehicles and engine codes.
As fluid circulates through its core, high-efficiency turbulators help transfer heat to the passing airflow, which helps lower ATF operating temperature. If elevated transmission-fluid temperature is contributing to overheating on your vehicle, adding this cooler helps manage it. It is compatible with OEM cooler systems and measures approximately 11 x 5 7/8.
Backed by Hayden's decades of automotive cooling experience.
