GENERAL DESCRIPTION

G EN ER AL DESC RIPTIO N
M1233000100038
This automatic transaxle is made up of the following main parts.
The torque converter employs a 3 element, 1 step, 2 phase lock-up clutch.
The gear train is made up of 3 multi-plate clutches, 2 multi-plate brakes and 2 planetary gears made up of a
sun gear, carrier, pinion gear and annulus gear.
The cases consist of a converter housing, transaxle case, rear cover and a valve body cover.
Parts related to oil pressure regulation are the oil pump, which pressurizes the oil; the regulator, which
controls the pressure setting; the solenoid valve, which changes the oil pressure with electrical signals; the
pressure control valve, which controls the oil pressure coming from the solenoid valve that effects each clutch
and brake; each kind of valve, which carry out the retention of the oil pressure through the lines; and finally
the valve body, which houses all the valves.
