A clutch arrangement for a transmission which comprises a wet separating clutch having a clutch housing, in which a clutch piston separates an interior space from a pressure chamber. The separating clutch is engaged by pressurizing the pressure chamber with an actuating pressure so that the clutch piston moves into an actuation position and, as a result, two clutch halves, located in the interior space and surrounded by fluid, frictionally engage one another. So as to reliably engage the separating clutch without impairing the surrounding components with the fluid, the actuating pressure includes at least one compensation pressure portion that corresponds to the counter pressure depending on the fluid located in the interior space opposing the clutch piston during transfer into the actuation position. A method of controlling a separating clutch, and a computer program product and a data medium incorporating the computer program product are also disclosed. 110-. (canceled)111.
