Speedmaster®
GM 4L80-E Billet Adjustable Low Band Servo Piston Kit
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.

The product is definitely an upgrade over factory I would recommend buy it The problem I had was there are no assembly instructions and it does not come with seals This was my first time going in a 4l80 and i had no clue how this was to be installed does any parts from the old servo need to be switched over or does it install as is
