Abstract
A lock-up control system is disclosed wherein the lock-up state of a torque converter is temporally released during gear shifting operation in an automatic transmission even if an automotive vehicle is operating in a predetermined lock-up range. A sensor generates an oil temperature compensation signal indicative of the temperature of oil used in the automatic transmission. The time duration of temporary release of the lock-up state is variable with variation in the oil temperature compensation signal.
