AUTOMATIC TRANSMISSION SYSTEM
OUTLINE
TECHNICAL FEATURES
The three-speed Automatic Transmission
(AfT)
system used in the MUV controls gear selection by utilizing a torque con-
verter and three hydraulic shift clutches.
To control the hydraulic clutches to shift, the system changes the supply of hydraulic pressure to each clutch (1st, 2nd, 3rd )
by activating the respective spool valves with the corresponding solenoid valves. Each solenoid valve is controlled by the
PCM, that detects the signa l from each sensor and switch.
The hydraulic oil for this system is the engine oil, which is supplied from the engine lubrication oil pump (page 5-2),
The valve body, which incorporates solenoid valves and spool valves, that is positioned on the crankcase cover to facilitate
maintenance (page 14-28)
The sub-transmission is positioned in front of the output shaft, and selecting Drive, Neutral, or Reverse can be made
mechanically by operating the selector lever located near the steering wheel.
