The Overflow Tank for GM Powerglide by ATI Performance is a precision-engineered coolant recovery system designed specifically for Chevrolet Powerglide automatic transmissions. This component addresses a critical cooling management need in vintage and hot rod builds where transmission temperature control directly impacts reliability and longevity.
Manufactured by ATI Performance, a brand recognized for quality transmission cooling solutions, this overflow tank features a compact design measuring 12.85 inches in height with a footprint of 3.9 x 2.6 inches—engineered to fit tight engine bays typical of classic Chevrolet platforms. The lightweight construction at just 1.37 pounds minimizes parasitic weight while maintaining structural integrity under thermal cycling and pressure fluctuations inherent to automatic transmission operation.
Builders and mechanics working on Chevrolet Powerglide installations—from mild restorations to high-horsepower street and strip applications—will benefit from this overflow tank, which ensures that transmission fluid stays within optimal operating temperature ranges, maintaining consistent fluid levels essential for proper shift quality and torque converter function.
