Abstract
A method is disclosed for limiting coolant temperature at a coolant flow exit port for a hydrokinetic torque converter in a powertrain for a vehicle having an engine and a power transmission mechanism, wherein the transmission and the torque converter are disposed in a common coolant flow circuit whereby a coolant flow line from the torque converter to a cooler is protected from failure due to excessive coolant temperature.
