OIL PUMP DESCRIPTIONA6E571419220201Outline
•The light-weight, compact, and quiet trochoid type oil pump reduces pump driving torque.
•The direct drive type oil pump is placed behind the torque converter.
Structure/Operation
•The outer rotor and inner rotor are installed in the oil pump housing.
•The inner rotor in the oil pump housing is driven by the torque converter.
•When the inner rotor in the oil pump rotates, the ATF is drawn to the oil pump. The discharge amount is
proportional to the rotating speed of the torque converter.

When the clutch pressure is not applied
•When the clutch drum rotates, centrifugal force acts on the residual ATF in the clutch chamber to push against
the piston. However, centrifugal force also acts on the ATF filled in the centrifugal balance clutch chamber to
push back the piston. As a result, the two forces are eliminated and the piston remains stationary, thus
preventing clutch engagement.
When the clutch pressure is applied
•When clutch pressure is applied to the clutch chamber, the clutch pressure overcomes the oil pressure and the
spring force in the opposite centrifugal balance clutch chamber, and pushes the piston to engage the clutches.
Because the centrifugal force acting on the clutch pressure in the clutch chamber is canceled by another
centrifugal force acting on the ATF filled in the centrifugal balance clutch chamber, the influence of the
centrifugal force created by the clutch drum revolution speed is eliminated. As a result, stable piston pushing
force is obtained in all rotation ranges, and smoother shifts can be made.
End Of SieCONTROL VALVE BODY DESCRIPTIONA6E571421100201Outline
•The control valve body is composed of four bodies: the sub lower body, lower body, internal body, and the upper
body.
•To minimize the component in the control valve body, clutch engagement is electronically controlled, hydraulic
circuits were simplified and the valve types reduced.

ON/OFF type (two-way)
Normal low
•De-energized (OFF)
—The TCM does not apply an electric current to the solenoid valves. The rod moves upward by hydraulic
pressure and the drain port opens.
•Energized (ON)
—The TCM applies an electric current to the solenoid valves. This excites the coil and forces the rod to move
downward to retain hydraulic pressure.

Automatic Transaxle Fluid (ATF) Level Inspection
Caution
•The ATF amount varies according to ATF's temperature. Therefore, when checking the ATF level or
replacing the ATF, use a thermometer to measure the temperature then adjust the ATF amount to
the specified level according to the specified temperature.
1. Park the vehicle on level ground.
2. Apply the parking brake and position wheel chocks securely to prevent the vehicle from rolling.
3. Adjust the length of the thermistor probe measure to the measure same as the dipstick and hold the probe with
a paper holder.
4. Insert into the filler tube and measure the
temperature.
5. Warm up the engine until the ATF reaches (60—
70 °C {140—158 °F}).
Caution
•Do not warm the transaxle by performing
stalls. This will damage the torque
converter.
Note
•In some cases it may be necessary to
inspect the ATF in the cool range 15—25 °C
{59—77 °F} before warming up the engine.
6. While depressing the brake pedal, shift the selector lever to each range (P—M), pausing momentarily in each
range.
7. Shift back to P position.
Note
•If the ATF level is too high or too low in hot condition, the following problems may be the cause.
8. While the engine is idling, verify that the ATF level
is in the HOT (65 °C {149 °F}) range. Add the
ATF specified type of, if necessary. (See K2–80

Warning
•When the transaxle and ATF are hot, they can badly burn you. Turn off the engine and wait until
they are cool before changing the ATF.
1. Remove the oil dipstick.
2. Remove the oil drain plug and washer.
3. Drain the ATF into a container.
4. Install a new washer and the drain plug.
Tightening torque
39—54 N·m {3.9—5.6 kgf·m, 29—40 ft·lbf}
5. Add the specified type of ATF through the oil filler
tube, until ATF level reaches lower notch of

Note
•Input signals of the TR switch can be inspected with a WDS or equivalent. (See K2–90 TCM
INSPECTION.)
Inspection of Operation
1. Verify that the starter operates only with the ignition switch at the START position and the selector lever in P
and N positions.
•If not as specified, inspect for continuity at the TR switch. (See K2–80 Inspection of Continuity.)
2. Verify that the back-up lights illuminate when shifted to R position with the ignition switch at the ON position.
•If not as specified, inspect for continuity at the TR switch.
Inspection of Continuity
1. Disconnect the TR switch connector.
2. Inspect for continuity at the TR switch.
•If not as specified, adjust the TR switch, then
reinspect the TR switch. (See K2–83
