Radiator GM A & G Body w/ Trans Cooler

The Griffin Radiator GM A & G Body with Trans Cooler (MPN 6-70006) is a purpose-built cooling solution for 1967–1979 GM A-Body and G-Body vehicles. This aluminum radiator combines a high-capacity core design with integrated transmission cooler capability, delivering reliable thermal management for both street and restored muscle car applications where factory cooling capacity falls short of modern demands or upgraded engine performance.

Measuring 25.5 inches wide by 39.6 inches tall with a 3-inch-thick core, this Griffin radiator is engineered to fit the factory mounting location while maximizing internal fluid volume and heat dissipation. The MegaCoolTube design increases surface area for more efficient heat rejection compared to traditional tube-and-fin construction. Driver-side inlet and passenger-side outlet configuration ensures proper coolant flow direction through the engine block. The integrated transmission cooler circuit protects automatic transmission fluid from thermal degradation during sustained driving, towing, or performance use—critical for longevity in vehicles with higher-output powerplants or custom engine swaps common in the A-Body and G-Body restoration community.

This radiator serves restomod builders, hot rod enthusiasts, and owners of high-performance Chevelles, Novas, Pontiac Lemanss, and related platform vehicles. Whether upgrading from a worn original core or supporting an engine upgrade that exceeds the factory cooling system's capacity, the Griffin radiator with transmission cooler eliminates overheating issues while maintaining authentic under-hood appearance with natural aluminum finish. The 35.2-pound weight is typical for aluminum construction and manages heat more effectively than heavier copper-brass alternatives.
