ABSTRACT:
A manual valve comprises a spool having two lands slidably disposed in a bore of a housing for movement to a P range, a R range, a N range, a D range, a II range and a I range. The manual valve is formed with an inlet port and five outlet ports. The first and second outlet ports are allowed to communicate with the inlet port to receive a line pressure when the spool is set to R range. The second outlet port is allowed to communicate with said inlet port when the spool is set to N range. The second and third outlet ports are allowed to communicate with said inlet port when the spool is set to D range. The third and fourth outlet ports are allowed to communicate with the inlet port when the spool is set to II range. The third, fourth and fifth outlet ports are allowed to communicate with the inlet port when the spool is set to I range. The first inlet port, second inlet port, inlet port, third outlet port, fourth outlet port and fifth outlet port are arranged in this order along the axial direction of the spool.
