Removal and Installation INFOID:0000000004305174
COMPONENTS
CAUTION:
• Never reuse CSC (Concentric Slave Cylinder). B ecause CSC slides back to the original position
every time when removing transaxle assembly. At th is timing, dust on the sliding parts may damage
a seal of CSC and may cause clut ch fliud leakage. Refer to CL-12, " 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-16, " Removal and Installation " (RS5F91R
models), MT-58, " 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.

CAUTION:
Measure flywheel outer face (not on knock pin and clutch cover
mounting hole).
INSTALLATION
1. Clean clutch disc and input shaft splines to remove grease and dust caused by abrasion.
2. Apply recommended grease to clutch disc and input shaft splines. CAUTION:
Be sure to apply grease to the points specified. Ot herwise, noise, poor disengagement, or damage
to the clutch may result. Excessive grease may cause sl ip or shudder. If it adheres to CSC seal, it
will cause clutch fluid l eakage. Wipe off excess grease.

• After performing each TROUBL E DIAGNOSIS, perform “DTC
Confirmation Procedure”.
If the repair is completed the DTC should not be displayed in
the “DTC Confirmation Procedure”.
• Always use the specified br and of CVT fluid. Refer to MA-14, " Flu-
ids and Lubricants " .
• Use lint-free paper, not cloth rags, during work.
• After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
Service Notice or Precaution INFOID:0000000004666859
CVT FLUID COOLER SERVICE If CVT fluid contains friction material (clutches, brakes , etc.), or if an CVT is replaced, inspect and clean the
CVT fluid cooler mounted in the radiator or replace t he radiator. Flush cooler lines using cleaning solvent and
compressed air after repair. For CVT fluid cooler cleaning procedure, refer to CVT-18, " CVT Fluid Cooler
Cleaning " . For radiator replacement, refer to
CO-38 .
OBD-II SELF-DIAGNOSIS • CVT self-diagnosis is performed by the TCM in comb ination with the ECM. The results can be read through
the blinking pattern of the malfunction indi cator lamp (MIL). Refer to the table on CVT-51, " CONSULT-III
Function (TRANSMISSION) " for the indicator used to display each self-diagnostic result.
• The self-diagnostic results indicated by the MIL ar e automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure on CVT-30, " OBD-II Diagnostic Trouble Code (DTC) " to complete the
repair and avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-541, " Introduction " .
• Certain systems and components, especially those re lated to OBD, may use the new style slide-lock-
ing type harness connector. For descripti on and how to disconnect, refer to PG-64 . MEF040DA

CAUTION:
Delete CVT fluid deterioration date with CONS ULT-III after changing CVT fluid. Refer to CVT-51," CONSULT-III Function (TRANSMISSION) " .
CVT Fluid Cooler Cleaning INFOID:0000000004666864
Whenever a CVT is repaired, overhauled, or replaced, t he CVT fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can be tr apped or become deposit in the CVT fluid cooler. This
debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.
In either case, malfunction of the newly serviced CVT may occur.
Debris, if present, may deposit as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
CVT FLUID COOLER CLEANING PROCEDURE
1. Identify the CVT inlet and outlet fluid cooler hoses.
2. Position an oil pan under the inlet and outlet cooler hoses. Fluid status Conceivable cause Required operation
Varnished (viscous
varnish state) Clutch, brake
scorched Replace the CVT fluid and check the
CVT main unit and the vehicle for
malfunctions (wire harness, cooler
pipes, etc.)
Milky white or cloudy Water in the fluid Replace the CVT fluid and check for places where water is getting in.
Large amount of
metal powder mixed
in fluid Unusual wear of
sliding parts within
CVT Replace the CVT fluid and check for
improper operation of the CVT. Fluids

b. If one or more pieces of debr
is are found that are over 1 mm
(0.040 in) in size and/or peeled clutch facing material is found in
the coffee filter, the fluid cooler is not serviceable. The radiator/
fluid cooler must be replaced and the inspection procedure is
ended.
CVT FLUID COOLER FINAL INSPECTION After performing all procedures, ensure that all remaining oil is cleaned from all components.

Lock-up and Select Control System Diagram
Lock-up Released In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by the
torque converter clutch solenoid and the lock-up apply pressure is drained.
In this way, the torque converter clutch piston is not coupled.
Lock-up Applied In the lock-up applied state, the torque converter clutch control valve is set into the locked state by the torque
converter clutch solenoid and lock-up apply pressure is generated.
In this way, the torque converter clutch piston is pressed and coupled.
Select Control When shifting between “N” (“P”) ⇔“D” (“R”), optimize the operating pressure on the basis of the throttle posi-
tion, the engine speed, and the secondary pulley (out put) revolution speed to lessen the shift shock.
