In an arrangement for automatically changing gear in an epicyclic change-speed gearbox from a previous gear, in which a first frictional connection (clutch or brake) is engaged, into another gear, in which a second frictional connection is engaged, the working pressure for engaging the first frictional connection is switched off when the working pressure for engaging the second frictional connection reaches a significant pressure value. The pressure value is determined by comparison with a reference parameter which depends on the load torque. |
