<p>Vehicle transmission 10, possibly six speed manual or automated-manual, having input shaft 12, coaxial output shaft 14, countershaft / layshaft 18, first idler gear 48 rotatable relative to input shaft 12, first coupling element 58 fixed to input shaft 12, second coupling element 52 fixed to first idler gear 48, second idler gear 90 rotatable relative to input shaft 12, third coupling element 92 fixed to second idler gear 90, and shift element 82 movable between first coupling position in which first 58 and second 52 coupling elements are connected, and second coupling position in which first 58 and third 92 coupling elements are rotationally fixed, possibly also synchronising speed of elements, to select first and second gears. First 48 and second 90 idler gears may be mounted respectively on output 14 and input 12 shafts. Transmission 10 may have third idler gear 30 connectable to output shaft 14.</p> |
