Description

The Sonnax Smart-Tech 10-clutch drum kit 28756-25K for GM Powerglides features a 35% larger piston that maximizes both engaging and holding capacity of the 10-clutch system. Smart-Tech components give you the option to reduce line pressure for greater efficiency, or drop to seven frictions for less parasitic drag and improved heat dissipation while retaining 10-clutch capacity.
