GM TH700R4 Trans. Brkt.

The Holley GM TH700R4 Transmission Bracket is a precision-engineered steel throttle cable bracket designed specifically for General Motors TH700R4 automatic transmissions paired with Holley 4011 carburetors. This component bridges the critical interface between your carburetor's throttle linkage and the transmission's kick-down mechanism, ensuring synchronized throttle and transmission response during acceleration and gear changes.

Constructed from cadmium-plated steel, this bracket provides corrosion resistance and durability in engine bay environments while maintaining precise dimensional tolerances required for reliable mechanical linkage operation. The cadmium plating protects against rust and oxidation, extending service life even in demanding conditions. Proper bracket installation is essential to carburetor and transmission performance—misalignment or binding in the throttle cable path can result in sluggish throttle response, transmission shift hesitation, or failure to engage kick-down, all of which degrade drivability and efficiency.

This bracket is engineered for street and performance builds running TH700R4 transmissions with Holley 4011 carburetors—a common configuration in muscle car restorations, classic car builds, and carbureted engine swaps. It is sold individually, so confirm your build requirements before ordering. Proper installation requires understanding of transmission linkage geometry and carburetor mounting specifics; consult your carburetor and transmission documentation to ensure correct fitment.

The TH700R4 remains a popular choice for vintage and restomod applications due to its overdrive fourth gear and modern internal design, and a quality throttle cable bracket is a non-negotiable component for reliable operation. Holley's OEM-standard engineering ensures compatibility and performance when combined with their 4011 carburetors.
