ABSTRACT:
A high performance clutch pack assembly for use in the high gear clutch of a Powerglide transmission is disclosed. The present clutch assembly is disposed in a modified clutch drum having weight reduction features for receiving a modified clutch pack comprising up to ten friction disks and eleven steel disks, which represents a 150 per cent increase in surface contact area and holding force in comparison to the original equipment Powerglide clutch pack having only four friction disks and five steel disks. The present clutch pack assembly is actuated by a modified clutch piston having an increased stroke correlated to the increased number of friction disks providing maximum holding force for the present clutch pack assembly with minimal increase in rotating mass.
