Abstract
A fluid coupling control device of an automatic transmission includes a turbine chamber into which an operation fluid flows, an operation chamber which is separated from the turbine chamber and into which the operation fluid flows, a clutch mechanism which engages and disengages the input member with the output member, a piston member slid by a fluid pressure difference between the operation chamber and the turbine chamber so as to engage and disengage the clutch mechanism, a fluid source which supplies the fluid to the operation chamber and the turbine chamber, and a control device disposed between the fluid source and the operation chamber which controls the fluid pressure in the operation chamber based on the fluid pressure in the turbine chamber.
