A transfer gear train and dog clutch is provided for drive between the layshafts, a further dog clutch being provided between one of the layshafts and the output shaft. The transmission provides six sequential speed ratios with pre-selection of adjacent ratios, alternate speed ratios being driven respectively through one and the other clutch.
