Abstract

An automatic vehicle transmission has a clutch, operated by oil pressure, for high speed and another for low speed. These clutches are connected selectively by a switching valve to an oil pressure source. An automatic control valve (6) operates when the low speed clutch operates above a given speed. The valve immobilises the low speed clutch by putting the clutch interior oil pressure chamber in communication with its exterior and feeds oil under pressure to a pressure chamber in the high speed clutch to engage it. Sudden braking is a condition then catered for.
