An automatic transmission for a motor vehicle comprises a power transmitting system divided into two gear-change units with respect to an input shaft for receiving the power from the engine, the power being transmitted to an output shaft through the two units, each of having respective counter shafts. The counter shaft of one of the units is provided thereon with a first gear stage meshed with a first drive gear fixedly supported on the input shaft. Control of the engine braking at the first-gear stage is accomplished by the engagement or disengagement of the lock up clutch. |
