Abstract
An automatic transmission hydraulic control system is provided with lubrication and cooler circuits fed in parallel. The lubrication circuit is fed by regulated pressure which prevents lubrication starvation concerns under extremes of temperature and speed conditions. As the lubrication demand increases the controlled pressure increases the lube flow to meet the component lubrication requirements.
