Abstract
The main pressure in the gearing which under normal operating conditions is 150% of the amount required to transmit the then-present torque is reduced to 100% when an upshift takes place under load or a downshift takes place under no load. For a downshift under load and an upshift under no load the pressure is reduced to about 30%. The position of the control rod of an injection pump at the beginning of a shift operation is stored until the shift is completed. This allows the present system to cooperate with a system wherein the control of the injection pump is shifted from the gas pedal to a regulator during gear shifts.
