ABSTRACT:
A control system for use in an automatic transmission which is connected to an engine comprises: a fluid coupling for transmitting a torque between an input member and an output member; a lock-up clutch adapted to be selectively engaged with and released from the input member; and a variable capacity type viscous coupling arranged in series between the lock-up clutch and the output member. The control system comprises: a lock-up detector for detecting that the lock-up clutch is engaged; an output state detector for detecting an output state of the engine; a torque transmission capacity determiner for determining a torque transmission capacity of the variable capacity type viscous coupling in accordance with the output state of the engine which is detected by the output state detector, if the lock-up detecting means detects that the lock-up clutch is engaged; and a mechanism for setting the torque transmission capacity of the variable capacity type viscous coupling to said determined torque transmission capacity.
