Patent ID: 7226380

Claim:
An automatic transmission comprising: a rotatably driven input shaft; a first planetary gear unit including first, second, third, and fourth rotary components; reduced speed rotation output means for receiving input rotation from said input shaft, for reducing the speed of the input rotation and for outputting rotation at the reduced speed to said first rotary component, said reduced speed rotation output means comprising a speed reducing second planetary gear unit that comprises a reduced speed rotary element, an engaging component for controlling rotation of the reduced speed rotary element, an input rotary component that receives as input the rotation of said input shaft, and a carrier, said reduced speed rotary element being rotatable at a reduced speed based on the rotation of said input rotary element and fixation against rotation of said intermediate element; a first clutch that is engageable to connect said input shaft and said second rotary component; a second clutch that is engageable to connect said input shaft and said third rotary component; an output unit for outputting the rotation of said fourth rotary component; wherein said automatic transmission provides at least five forward speeds, one reverse speed, and a directly coupled state wherein the rotation of the input shaft is output without change in speed by engagement of said first clutch and said second clutch in fifth speed; wherein said reduced speed rotation output means is located on one axial side of said first planetary gear unit, and said output unit is located between said first planetary gear unit and said reduced speed rotation output means; wherein said first clutch and said second clutch are located on the axial side of said first planetary gear unit opposite said one axial side; and wherein said engaging component is a brake for fixing the intermediate element against rotation; wherein said brake is on the axial side of said first planetary gear unit opposite said speed reducing second planetary gear unit; and said brake is operated by a hydraulic servo formed in a wall of a case housing said first planetary gear unit.
