The Trans Mount Adapter Bracket GM LS to 4L60E from HOOKER solves one of the most common challenges in LS engine swaps: transmission mounting geometry mismatch. When retrofitting a modern LS powerplant into older GM platforms or custom chassis, the original engine bay mounting points rarely align with the 4L60E transmission's bellhousing flange. This adapter bracket bridges that gap, allowing seamless integration without custom fabrication or engine repositioning. Mechanics and enthusiasts performing LS conversions rely on this bracket to maintain proper drivetrain alignment while preserving factory-style installation simplicity.
Engineered by HOOKER, a trusted name in performance engine swap components, this adapter bracket is precision-manufactured to exact OEM specifications for both the LS engine family and 4L60E transmission. The bracket's rigid construction maintains critical transmission centerline alignment, preventing vibration, noise, and premature wear on motor mounts, transmission bushings, and driveline components. At just 2.4 pounds with compact dimensions (5.38 x 2 x 6.75 inches), it integrates cleanly into tight engine bays without requiring modification to adjacent components. The design accommodates standard motor mount geometry while ensuring the transmission mounts sit at the factory-correct angle relative to the frame.
This bracket is essential for anyone performing an LS swap into second-generation F-body Camaros, third-generation Camaros, Firebirds, or custom hot rod chassis where manual-to-automatic transmission conversions are planned. The adapter works exclusively with LS-series engines (LS1, LS2, LS3, LS6, LQ4, LQ9, and similar variants) mated to the GM 4L60E four-speed automatic transmission. Professional installers recommend using quality motor mounts and transmission crossmember hardware alongside this bracket to ensure optimal powertrain durability. Proper installation takes 1–2 hours and requires only basic hand tools, making it accessible for both experienced fabricators and dedicated DIY builders.
