ABSTRACT:
A high performance clutch pack for use in the high gear clutch of a POWERGLIDE transmission is disclosed. The present clutch pack is disposed in a modified clutch drum including fluid exhaust vents to reduce piston drag and weight reduction features for accommodating up to ten friction disks and eleven steel disks representing a 150 percent increase in holding force in comparison to the stock POWERGLIDE clutch pack, which typically provides only four friction disks and five steel disks. In one embodiment the steel disks include elliptically shaped holes at predetermined locations for imparting turbulence to the flow of transmission fluid within the clutch pack and also feature anti-drag spacers for reducing parasitic drag during freewheeling. The clutch pack is actuated by a modified clutch piston having an increased stroke correlated to the increased number of friction disks delivering maximum holding force with minimal increase in rotating mass.
