摘要：A power transmission having two simple planetary gear sets produces fiveforward speed ratios and a reverse ratio. The two highest forward speed ratios, fourthand fifth, are overdrive ratios using the same input member in one of the planetary setsand exchanging output members in the other planetary set. The power transmission alsohas a continuous input drive to a sun gear of one of the planetary sets and incorporatesfive clutches and two brakes to establish the five forward speed ratios. The clutches andbrakes are disposed in parallel with the clutch and one-way device to permit morecontrol of the shift timing. The continuous input to the sun gear is employed in all theforward ratios and in the reverse ratio.
