23C-2 AUTOMATIC TRANSAXLE OVERHAUL
GENERAL DESCRIPTION
GENERAL DESCRIPTION
M1233000100588
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 4 multi-plate clutches, 2 multi-plate brakes, 2 planetary gears, band type brake
and 2 one-way clutch 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 con-
trols the pressure setting; the solenoid valves, which change the oil pressure with electrical signals; the pres-
sure control valve, which controls the oil pressure coming from the solenoid valve that affects each clutch and
brake; each kind OD valve, which carry out the retention of the oil pressure through the lines; and finally the
valve body, which houses all the valves.
