10. Remove transmission range switch (2) from transaxle case. : Bolt
11. Remove oil pan bolts.
12. Remove oil pan and oil pan gasket.
13. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
•If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-40
.
14. Remove magnets from oil pan.
15. Remove control valve assembly according to the following procedures.
a. Remove snap ring (1) from terminal body (2). CAUTION:
Do not expand snap ring (1) excessively.
b. Push terminal body (2) into transaxle case.
c. Remove control valve assembly fitting bolts (A), (B) and ( C).
Bolt length, number and location:
d. Remove control valve assembly from transaxle case.
CAUTION:
Be careful not to drop manual valve.

4. Set Tool (A) on spring retainer assembly, and remove snap ring from transaxle case while compressing spring retainer assem-
bly.
CAUTION:
Set Tool directly over return springs.
5. Remove spring retainer assembly from transaxle case. CAUTION:
Do not remove return springs from spring retainer.
6. Apply compressed air into the oil hole on transaxle case as shown in the figure to raise piston while strongly pressing the
whole low & reverse brake piston by hand. When applying com-
pressed air, strongly press the whole piston and adjust the pres-
sure so that it is raised evenly. Portion (A) (low & reverse brake
pressure) especially tends to tilt.
CAUTION:
Apply air gradually and allow low & reverse brake piston to
come out evenly.
7. Remove low & reverse brake piston from transaxle case by turn- ing it.
8. Inspect transaxle case. Replace if damaged or worn.
9. Remove seal lip (1) and D-ring (2) from low & reverse brake pis- ton (3).

TCS FunctionINFOID:0000000005928470
• Spinning of the drive wheels is detected by the ABS/TCS/VDC control unit using inputs from the wheel speed sensors. If wheel spin occurs, the drive wheel right and left brake fluid pressure control and engine
fuel cut are conducted while the throttle value is restricted to reduce the engine torque and decrease the
amount of wheel spin. In addition, the throttle openi ng is controlled to achieve the optimum engine torque.
• Depending on road condition, the vehicle may have a sluggi sh feel. This is normal, because optimum trac-
tion has the highest priority during TCS operation.
• TCS may be activated during sudden vehicle acceleration, wide open throttle acceleration, sudden transmis- sion shifts or when the vehicle is driven on a road with a varying surface friction coefficient.
• The SLIP indicator lamp flashes to inform the driver of TCS operation.
VDC FunctionINFOID:0000000005928471
• In addition to the ABS/TCS function, the driver steering amount and brake operation amount are detected
from the steering angle sensor, and the vehicle's driving status (amount of under steering/over steering) is
determined using inputs from the yaw rate/side/decel G sensor, wheel speed sensors, etc. and this informa-
tion is used to improve vehicle stability by controlling the braking and engine torque application to the
wheels.
• The SLIP indicator lamp flashes to inform the driver of VDC operation.
• During VDC operation, the vehicle body and brake pedal may vibrate lightly and a mechanical noise may be
heard. This is normal.
• The ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may turn on when the vehicle is
subject to strong shaking or large vibration, such as when the vehicle is on a turn table or a ship while the
engine is running or steep slope. In this case, restart the engine on a normal road and if the ABS warning
lamp, VDC OFF indicator lamp and SLIP indicator lamp turn off, there is no problem.
Wheel SensorsINFOID:0000000005928472
The front sensor units consist of a gear-shaped sensor rotor and a
sensor element. The element contains a magnet around which a coil
is wound. The front wheel sensors are installed on the front of the
wheel knuckles. As the wheel rotates, the sensor generates a
square-wave signal. The frequency increases as the wheel speed
increases.
The rear sensor units consist of wheel hubs with a series of internal
magnets and a sensor element. The rear wheel sensors are installed
on the inner side of the wheel knuckles. As the wheel rotates, the
sensor generates a square-wave signal. The frequency increases as
the wheel speed increases.
Fail-Safe FunctionINFOID:0000000005928473
ABS/EBD SYSTEM
In case of an electrical malfunction with the ABS, the ABS warning lamp, VDC OFF indicator lamp and SLIP
indicator lamp will turn on. In case of an electrical malfunction with the EBD system, the BRAKE warning lamp,
ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp will turn on.

Removal and InstallationINFOID:0000000005929001
COMPONENTS
CAUTION:
• Never reuse CSC (Concentric Slave Cylinder). Because CSC slides back to the original position
every time when removing transaxle assembly. At this timing, dust on the sliding parts may damage
a seal of CSC and may cause clutch fluid leakage. Refer to CL-13, "
Removal and Installation".
• Never bring any grease to the clutch disc faci ng, pressure plate surface and flywheel surface.
• When installing, be careful that grease applied to input shaft does not adhere to clutch disc.
• Never clean clutch disc using solvent.
REMOVAL
1. Remove transaxle assembly from the vehicle. Refer to MT-17, "Removal and Installation" (RS5F91R
models), MT-61, "
Removal and Installation" (RS6F94R models).
2. Loosen clutch cover bolts evenly. Then remove clutch cover and clutch disc.
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc
• Measure clutch disc runout and spline backlash. If either measure- ment exceeds the specificat ion, replace clutch disc.
• Check clutch disc for burns, discoloration or oil or grease leakage. Replace if necessary.

4. Input shaft A. First step (MR18DE engine models) B. First step (HR16DE engine models)
C. Final step Apply lithium-based grease including molybdenum disulphide
