Control system for a multiple ratio transmission having a lockup clutch torque converter
This patent describes a power transmission mechanism for a driveline for a vehicle powered by an internal combustion engine. The process comprises: a hydrokinetic torque converter having a bladed impeller housing driven by the engine, a bladed turbine in the housing, a bladed stator and a turbine shaft connected to the turbine; multiple ratio gearing having a torque input member and a torque output member with plural torque flow paths defined by gear elements between the input and output members and having clutch and brake servo means for establishing selectively four forward driving speed ratios and a reverse ratio; and the highest speed ratio being an overdrive, the second highest speed ratio being a direct one-to-one speed ratio and the third highest speed ratio being an underdrive.
