68-77 GM A-Body Radiator Auto Trans Black

The 68-77 GM A-Body Radiator Auto Trans Black from Cold Case Radiators is a direct-fit cooling solution engineered for classic General Motors A-body muscle cars and daily drivers from 1968 through 1977. Built for vehicles equipped with automatic transmissions, this radiator restores efficient heat dissipation and modern cooling reliability to second-generation Chevelle, Cutlass, Skylark, and Tempest platforms. Enthusiasts upgrading aging factory radiators benefit from improved thermal management, reduced engine temps, and the ability to run tighter fan clutches or electric cooling systems without compromise.

This aluminum construction radiator measures 34.75 inches wide by 18.75 inches tall with a 3-inch core depth, delivering substantial cooling capacity in a classic envelope that preserves underhood aesthetics. The design features a driver-side inlet and passenger-side outlet configuration matched to factory manifold and heater hose locations, eliminating adapter complexity during installation. Black powder-coat finishing protects against corrosion while complementing modern restorations and street machine builds. The automatic transmission cooler circuit is integrated, supporting stock or upgraded transmission cooling without additional external lines.

Hot-rodders, restorers, and weekend warriors running 350, 400, or 455-cubic-inch engines in A-body platforms will find this radiator essential for sustained performance and street reliability. The compact 7-by-23-by-38-inch shipping profile weighs 24 pounds and ships efficiently to your garage. OEM hose connections and mounting points align with 1968–1977 Chevrolet, Oldsmobile, Buick, and Pontiac A-body frame rails, ensuring bolt-in fitment without custom fabrication. Pair this radiator with a quality 16-inch electric fan or properly functioning mechanical setup to maximize cooling efficiency and preserve engine longevity during spirited driving or daily commutes.
