Automatic transmission hydraulic control system with parallel lubrication and cooler circuits

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 incre...
