Precautions UCS005XJ
NOTE:
If any malfunction occurs in the RE0F08A model transaxle, replace the entire transaxle assembly.

Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect negative
battery cable. Because battery voltage is applied to TCM
even if ignition switch is turned OFF.

When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are
not any bends or breaks on TCM pin terminal.

Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. CVT-54, "
TCM INSPECTION TABLE".

After performing each TROUBLE 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 brand of CVT fluid. Refer to MA-11,
"Fluids 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 PrecautionsUCS005XK
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 the 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-11, "RADIATOR" .

Revision: June 20062007 Versa
CVT Fluid Cooler CleaningUCS005XP
Whenever a CVT is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can be trapped 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.
3. Disconnect the fluid cooler inlet and outlet rubber hoses from the
steel cooler tubes.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4. Allow any CVT fluid that remains in the cooler hoses to drain into
the oil pan.
5. Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:

Wear safety glasses and rubber gloves when spraying
the Transmission Cooler Cleaner.

Spray Transmission Cooler Cleaner only with adequate
ventilation.

Avoid contact with eyes and skin.

Do not breath vapors or spray mist.
6. Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet hose until CVT fluid flows out of the
cooler inlet hose for 5 seconds.
7. Insert the tip of an air gun into the end of the cooler outlet hose.
8. Wrap a shop rag around the air gun tip and of the cooler outlet
hose.
9. Blow compressed air regulated to 5 to 9 kg/cm
2 (70 to 130 psi)
through the cooler outlet hose for 10 seconds to force out any
remaining CVT fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the CVT
fluid cooler steel lines to the transaxle.
12. Remove the banjo bolts.
13. Flush each steel line from the cooler side back toward the tran-
saxle by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.
14. Blow compressed air regulated to 5 to 9 kg/cm
2 (70 to 130 psi) through each steel line from the cooler
side back toward the transaxle for 10 seconds to force out any remaining CVT fluid.
15. Ensure all debris is removed from the steel cooler lines.
16. Ensure all debris is removed from the banjo bolts and fittings.
17. Perform CVT-19, "
CVT FLUID COOLER DIAGNOSIS PROCEDURE" .

CVT FLUID COOLER DIAGNOSIS PROCEDURE
NOTE:
Insufficient cleaning of the cooler inlet hose exterior may lead to inaccurate debris identification.
1. Position an oil pan under the transaxle's inlet and outlet cooler hoses.
2. Clean the exterior and tip of the cooler inlet hose.
3. Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:

Wear safety glasses and rubber gloves when spraying
the Transmission Cooler Cleaner.

Spray Transmission Cooler Cleaner only with adequate
ventilation.

Avoid contact with eyes and skin.

Do not breath vapors or spray mist.
4. Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet hose until CVT fluid flows out of the
cooler inlet hose for 5 seconds.
5. Tie a common white, basket-type coffee filter to the end of the
cooler inlet hose.
6. Insert the tip of an air gun into the end of the cooler outlet hose.
7. Wrap a shop rag around the air gun tip and end of cooler outlet
hose.
8. Blow compressed air regulated to 5 to 9 kg/cm
2 (70 to 130 psi)
through the cooler outlet hose to force any remaining CVT fluid
into the coffee filter.
9. Remove the coffee filter from the end of the cooler inlet hose.
10. Perform CVT-20, "

CVT FLUID COOLER INSPECTION PROCEDURE
1. Inspect the coffee filter for debris.
a. If small metal debris less than 1 mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the CVT fluid cooler/radiator can be re-used and
the procedure is ended.
b. If one or more pieces of debris 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.

Line Pressure and Secondary Pressure ControlUCS005XW

When an input torque signal equivalent to the engine drive force is sent from the ECM to the TCM, the
TCM controls the line pressure solenoid valve and secondary pressure solenoid valve.

This line pressure solenoid controls the pressure regulator valve as the signal pressure and adjusts the
pressure of the operating oil discharged from the oil pump to the line pressure most appropriate to the
driving state. Secondary pressure is controlled by decreasing line pressure.
NORMAL CONTROL
Optimize the line pressure and secondary pressure, depending on driving conditions, on the basis of the throt-
tle position, the engine speed, the primary pulley (input) revolution speed, the secondary pulley (output) revo-
lution speed, the brake signal, the PNP switch signal, the lock-up signal, the voltage, the target gear ratio, the
fluid temperature, and the fluid pressure.
FEEDBACK CONTROL
When controlling the normal fluid pressure or the selected fluid pressure, the secondary pressure can be set
more accurately by using the fluid pressure sensor to detect the secondary pressure and controlling the feed-
back.
Shift ControlUCS005XX
In order to select the gear ratio which can obtain the driving force in accordance with driver's intention and the
vehicle condition, TCM monitors the driving conditions, such as the vehicle speed and the throttle position and
selects the optimum gear ratio, and determines the gear change steps to the gear ratio. Then send the com-
mand to the step motor, and control the flow-in/flow-out of line pressure from the primary pulley to determine
the position of the moving-pulley and control the gear ratio.
