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 4L65E Level 4 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.
