ABSTRACT:
An automatic transmission comprising a fluid torque converter; a transmission gear comprising a first gear unit having three forward-speed gears and one reverse gear and a second gear unit having a high-speed gear and a low-speed gear; and a hydraulic control system comprising first and second shift valves for controlling the shifting between the speed gears of the first gear unit, a third shift valve for controlling the shifting between the high-speed gear and the low-speed gear of the second gear unit, a manual selector valve having five shift positions, i.e. D, I. L, R and P-position, and first, second and third solenoid valves related with the first, second and third shift valves respectively.
The automatic transmission is capable of providing six forward-speed automatic transmission when the manual selector valve is shifted to the D-position, three forward-speed automatic transmission including the first, third and fifth speeds when the manual selector valve is shifted to the I-position, three forward-speed automatic transmission including the first, third and fifth speeds and allowing effective engine braking when the manual selector valve is shifted to the L-position, and two-speed reverse automatic transmission when the manual selector valve is shifted to the R-position.
