3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.
+It is good practice to mark the point of specified engine
rpm on indicator.

5. Start engine, apply foot brake, and place selector lever in D
position.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately
release throttle.
+During test, never hold throttle wide open for more than 5
seconds.
Stall revolution:
2,350 - 2,850 rpm

DescriptionNLAT0061The line pressure solenoid valve regulates the oil pump discharge
pressure to suit the driving condition in response to a signal sent
from the TCM.
The line pressure duty cycle value is not consistent when the
closed throttle position switch is ªONº. To confirm the line
pressure duty cycle at low pressure, the accelerator (throttle)
should be open until the closed throttle position switch is

RemovalNLCL00451. Remove manual transaxle from vehicle. Refer to MT-18,
ªRemovalº.
2. Move withdrawal lever enough to remove release bearing, and
remove release bearing from clutch lever.
3. Support clutch lever claws with an appropriate wood block,
align retaining pin with A in the figure, and drive out spring pin
using a pin punch.
4. Pull out withdrawal lever and remove clutch lever.
SCL733
InspectionNLCL0046+Replace the release bearing if it is seized, damaged, faulty in
rotation direction, or has poor aligning function.
+Replace the withdrawal lever if its contact surface is worn
abnormally.
+Replace the clutch lever if its contact surface is worn abnor-
mally.
+Replace the dust seal if it is deformed or cracked.
InstallationNLCL0047CAUTION:
+Be sure to apply grease to the clutch components.
Otherwise, abnormal noise, poor clutch disengagement,
or clutch damage may occur. Wipe the excess grease off
completely, because it may cause the clutch components
to slip and shudder.
+Keep the clutch disc facing, pressure plate, and flywheel
free of oil and grease.
