Abstract
A six speed manual transmission having a double planetary gearset consisting of two simple planetary gearsets for use in a motor vehicle. The transmission includes an input shaft, a mainshaft rotatably connected by constant-mesh gearwheels to the input shaft, and an output shaft. This assembly provides two dissimilar fixed speed ratios, with a first power path using the first fixed speed ratio and a second power path using the second fixed speed ratio. The first power path includes a first sliding synchronizer clutch, a second sliding synchronizer clutch, and a first planetary gearset. The second power path includes a third sliding synchronizer clutch and a second planetary gearset. In addition, the first and second power paths share a common brake. The transmission provides a plurality of forward speeds, a braked neutral and a reverse drive. The transmission may be applied in either front wheel or rear wheel drive vehicles.
