Transmission Crossmember 1973-1977 GM A-Body

The Transmission Crossmember 1973-1977 GM A-Body by G Force Crossmembers is designed specifically for builders who require structural integrity when upgrading or swapping transmissions in classic Chevrolet, Pontiac, Oldsmobile, and Buick A-body platforms. This crossmember is essential for those installing modern TH400 transmissions, performing LS swaps, or restoring factory drivetrains.

Manufactured by G Force Crossmembers, this component is precision-engineered to maintain proper transmission geometry and prevent excessive movement that can damage mounts, driveshaft u-joints, and tunnel clearances. Its robust design accounts for torque transfer and vibration isolation, which are critical factors when running higher horsepower engines or forced induction setups.

A-body vehicles—including the Chevelle, GTO, Cutlass, and Skylark—will benefit from this crossmember when upgrading from original equipment or installing non-factory powertrains. It provides the necessary support for modern driveline demands while ensuring compatibility with 1973–1977 GM A-body vehicles.
