A gear train 10, for a single lay shaft automotive gearbox, comprises a main shaft 12 and a lay shaft 14 arranged parallel to one another. A plurality of gear pairs 42, 44, 46, 48 are spaced axially along the main and lay shafts 12, 14, each gear pair 42,44,46,48 comprising main and output shaft gears 42a, 44a, 46a, 48a and lay shaft gears 42b, 44b,4 6b, 48b meshed with the main and output shaft gears 42a, 44a, 46a, 48a. A plurality of dog rings 58a, 58b, 58c between the gear pairs couples a gear for rotation with a shaft. One of main shaft gears 46a is selectively coupleable to the input shaft 16 via dog ring 58b to transmit torque from the input shaft 16 to the lay shaft 14 to the output shaft 18, or by engaging both dog rings 58b, 58c with gear 46a direct drive is effected between the input shaft 16 and the output shaft 18. |
