GM 4L80-E Billet Adjustable Low Band Servo Piston Kit
Product Information
Overview
The purpose of the servo piston is to apply force to the rear band, controlling the band's grip on the transmission drum during gear changes. Adjusting the rear band is crucial for optimizing shift quality and transmission performance. This adjustable servo enables you to fine-tune the rear band's tension with ease, even while the transmission is still installed in the vehicle.
