ABSTRACT:
A lock-up control system for a lock-up type automatic transmission of an automotive vehicle.
The lock-up control system functions to temporally release lock-up operation of a torque converter of the transmission upon occurrence of a gear shift signal even if the automotive vehicle is operating within any one of lock-up ranges. Gear shifting detector means generates a gear shift signal having a time duration which is variable corresponding to the time duration of a corresponding gear shifting operation. The duration of the gear shift signal generated by the gear shifting signal may also be variable also with the magnitude of engine load.
