Transmission Mount Bracket

The ALLSTAR PERFORMANCE Transmission Mount Bracket (ALL 38072) is a weld-on engine mounting solution designed for builders and mechanics undertaking serious transmission installations on modified vehicles. This bracket serves as a critical structural component that locates and secures the transmission to the chassis, distributing dynamic loads while maintaining precise alignment—essential when upgrading powerplants, swapping transmission types, or building custom frames where factory mounts no longer apply.

Manufactured from 0.125-inch thick steel with a natural finish, this bracket provides the rigidity and durability required for high-vibration environments common in performance and competition vehicles. The 1 x 7/16-inch slot design allows for fine-tuning of transmission location and angle, a critical feature when integrating non-OEM drivetrains or compensating for frame modifications. The weld-on construction eliminates fastener shear points and vibration-induced loosening, creating a permanent, load-bearing joint that maintains structural integrity through sustained acceleration, engine braking, and lateral forces typical in road racing, drag racing, and off-road applications.

This bracket is ideal for fabricators and engine builders working with tube-frame vehicles, custom chassis platforms, or any application where transmission mounting points require relocation or customization. Installation requires welding to a suitable mounting surface—positioning and clamping the bracket securely before tack-welding and completing a full perimeter weld ensures optimal strength. With a compact footprint (4.15 x 1.4 x 12 inches) and minimal weight (0.72 lbs), it integrates seamlessly into tight engine bays while adding negligible mass to the overall build.
