GM TH700R4 Trans. Brkt.

The Holley GM TH700R4 transmission bracket is a purpose-built engine bay component designed for builders integrating a TH700R4 (700R4) overdrive transmission into GM engine swaps and custom installations. This bracket serves as the critical structural and locating interface between the transmission and the engine block, ensuring proper alignment and vibration isolation in high-performance and street applications.

Holley's engineering utilizes precision-machined steel to deliver a bracket that effectively handles both static loads and dynamic engine torque without flex or deflection. The design maintains correct transmission case geometry relative to the bellhousing, preventing misalignment that can lead to increased driveline vibration and compromised seal integrity. Weighing just 0.42 pounds, the compact design (7.65 x 2.65 x 10.65 inches) integrates seamlessly into tight engine bays typical of vintage and modern muscle car restorations.

This bracket is essential for engine swap builders, restoration shops, and powertrain engineers tackling TH700R4 installations. It is engineered for direct compatibility with GM TH700R4 transmissions and small-block engine platforms, making it a reliable choice for various automotive projects.
