Abstract
A lubrication system for multi-plate clutch assemblies is controlled to provide increased lube flow. During steady state operation, lube flow is increased periodically for a short time interval. At other times during steady state operation, the lube flow is maintained at a level requiring minimum fluid flow for the system.
