Transmission Mount Bushing

The ENERGY SUSPENSION Transmission Mount Bushing (Model 3.1142R) is a Hyper-Flex polyurethane replacement designed for GM F-Body vehicles from 1982 through 2002, including Camaro, Firebird, and Trans Am platforms. This transmission mount bushing serves as a critical vibration isolator between the engine bay and chassis, reducing harshness transfer during acceleration and deceleration while maintaining structural rigidity under load. Factory rubber mounts degrade over time, causing increased cabin noise, steering vibration, and poor shift feel—problems that become especially noticeable in modified or high-performance builds where engine torque exceeds original specifications.

Engineered from premium polyurethane compound with integrated steel reinforcement and cadmium-plated hardware, the ENERGY SUSPENSION Transmission Mount Bushing delivers superior durability compared to OEM rubber components. Polyurethane resists oil contamination, UV exposure, and thermal cycling far better than natural rubber, ensuring consistent performance across thousands of miles and multiple seasons. The Hyper-Flex formulation maintains elasticity under extreme temperature swings while providing a firmer response that reduces drivetrain slack—especially valuable for vehicles with aggressive throttle response or forced-induction upgrades where transmission mount compliance directly impacts power delivery consistency.

This kit is ideal for street and strip enthusiasts seeking to eliminate NVH (noise, vibration, and harshness) without sacrificing daily driveability. Installation requires basic hand tools and approximately one hour; the transmission must be safely supported during bushing replacement. Weighing 1.57 pounds and dimensioned at 3.95 x 2.35 x 8.85 inches, this bushing fits seamlessly into the existing transmission mount bracket without modification. Whether restoring a classic F-Body, building a restomod, or upgrading a high-mileage daily driver, the ENERGY SUSPENSION Transmission Mount Bushing provides proven reliability and measurable improvements in powertrain feel.
