1951–1962 Chevrolet All Models & Corvette NOS Powerglide Clutch Drum Snap Ring #3692700

Available for sale is a genuine General Motors New Old Stock (NOS) Powerglide Clutch Drum Snap Ring, GM part number 3692700, designed for 1951–1962 Chevrolet passenger cars, trucks, and Corvette applications equipped with the Powerglide automatic transmission. This original GM service replacement component is a critical internal transmission part and a valuable find for restorers and transmission rebuilders seeking authentic factory-correct Powerglide components.

The Powerglide automatic transmission was one of General Motors’ most successful early automatic transmissions and played a major role in Chevrolet’s postwar success. Introduced in the early 1950s, the Powerglide became known for its simplicity, durability, and smooth operation. It was widely used across Chevrolet passenger cars, Corvettes, and other applications throughout the 1950s and early 1960s.

The clutch drum snap ring is an important internal retaining component within the Powerglide transmission assembly. Its function is to securely hold clutch pack components in place inside the clutch drum, maintaining proper assembly alignment and ensuring reliable transmission operation. Correct installation and retention are essential for maintaining clutch engagement and hydraulic performance.

During transmission rebuilds, original snap rings can become worn, distorted, fatigued, or damaged from years of service and repeated disassembly. Replacing worn internal hardware helps ensure proper transmission assembly and long-term reliability.

This component is a true New Old Stock (NOS) GM service replacement part, meaning it was manufactured during the original production era and has never been installed. It retains original factory specifications, metallurgy, dimensions, and engineering standards intended by General Motors.

Unlike some aftermarket replacement components, NOS GM transmission parts provide factory-correct fitment and material quality. This is particularly important for restorers seeking authentic Powerglide rebuild components and reliable transmission operation.

For restoration professionals and transmission specialists, using original GM internal components helps preserve authenticity while maintaining proper transmission function. Whether rebuilding a Powerglide for a Chevrolet passenger car, Corvette, or other compatible application, this snap ring provides the correct factory-style solution.

As original Powerglide transmission components continue to become more difficult to locate, NOS internal service parts such as this clutch drum snap ring have become increasingly sought after by collectors, restorers, and vintage transmission rebuilders.
