Overview

GearStar GM 4L80E Level 5 Transmissions

GearStar GM high-performance transmissions are built to the horsepower, torque, and rear gear ratio specs of the engine that it will be matched to. Unlike other high-performance transmissions builders, GearStar individual transmissions are hand-built by one technician from start to finish. Before a transmission and torque converter leaves their facility, they are dyno tested for the equivalent of 100 miles, ensuring proper working condition.

GearStar GM 4L80E Level 5 transmissions with torque converter are built with the highest quality parts available. "Heart-pounding performance with industry leading experience"; select the proper transmission for your build and "strap yourself in to experience uncompromising performance" with the "legendary road-proven craftsmanship" of GearStar Performance transmissions.
