AUTOMATIC TRANSAXLE - TroubleshootingBased upon use of the troubleshooting
guide, the probable location of the prob-
lem should be estimated.
Checks should be made of fluid levels
and the condition of the ATF, as well as
bles; adjustments should then be made if
If a presumption has been made that
there is an abnormal condition some-
check the fault code, in order to determinethe probable location of the problem, by
When the abnormal system is discovered,
check each element (sensors, etc.) one byone, and make repairs as necessary.
“~^II_When the abnormal condition is pre-
sumed to be in the
orI-pressure-controlsystem, check by making an oil-pressure
If the problem is unusually dirty ATF,
of the clutch or brakes, or an abnormal
condition of the transaxle itself,
disassem-TROUBLESHOOTING
”N21EeAYFunctional malfunctions of the ELC4A/T can lead to other
problems, such as those described below:
(1) Improper maintenance and/or adjustments
(2) Malfunctions of the electronic control functions
(3) Malfunctions of mechanical functions
(4) Malfunctions of hydraulic control functions
(5) Malfunctions of engine performance
etc.In order to properly determine (“Troubleshoot”) the source of
these malfunctions, it is first essential to methodically ques-
tion the user concerning the details of the problem, such qs
the condition of the problem, the situation at the time the
problem occurred, and any other relevant information, all in as
much detail as possible. The user
shoutd also be asked
whether or not the problem has occurred more than once,
and under what conditions.
Subsequently, certain tests should be conducted in a certain
order, as described at the left.

7.Turn the adjustment screw of the regulator valve and adjustso that the line pressure
(kickdown brake pressure) a,becomes the standard value.
When the adjustment screw is turned to the clockwise, the
Lline pressure becomes lower; when it is turned to
counter-clockwise, it becomes higher.
Standard value:
870-890 kPa (124-127 psi)
Oil pressure change for each turq of
adjustment screw: 38
kPa (54 psi)
8. Check to be sure that the O-ring is installed on the upper
surface of the valve body at the place shown in the figure.
9.Replace the O-ring of the solenoid valve harness grommet
with a new one.
10. Insert the solenoid valve harness grommet in the axle case.
11. Install the valve body and oil temperature sensor, and then
(IO pieces) to
tighten valve body assembly mounting bolts
IO-12 Nm (7.5-8.5 ft.lbs.).A: 18 mm
(.709 in.) long
B: 25 mm
(.984 in.) long
C: 40 mm (1.575 in.) long
12. Install the oil filter.
13. Install a new oil pan gasket and oil pan.
14. Pour in the specified amount of Automatic transaxle fluid.
15. Make the oil pressure test. Readjust if necessary.
+-t
--,,
REDUCING PRESSURE ADJUSTMENTNZlFTAC(If the multi-use tester is not available)
1. Remove parts up to the oil filter in the same way as for
adjustment of the line pressure. The valve body need not
be removed.
+%2. Turn the adjustment screw of the lower valve body and_adjust so that the reducing pressure is the standard value.
When the adjustment screw is turned to the right, the
reducing pressure becomes lower; when it is turned to the
left, it becomes higher.

77. Install O-ring at center of top of valve body assembly (brakeoil pressure passage).
78. Replace the O-ring of the solenoid valve harness grommet
with a new one.
79.
Insert the solenoid valve connector into the case.
80. Insert the harness grommet into the case.
81.
Inserting the pin of the detent plate into the groove of the
manual valve, install the valve body assembly on the case.82. First insert the oil temperature sensor inside the case and
install to the case. Then install to the valve body. Tighten
valve body assembly mounting bolts
(IO pieces) to IO- 12

C : 40 mm (1.575 in.) long
83. Install oil filter. Tighten four oil filter mounting bolts to 5-7
Nm (4-5
ft.lbs.1.
84. Install five magnets in the five depressions provided on theoil pan.
Remove metal particles from the magnets and clean the
inside of oil pan then.
85. Install new oil pan gasket and oil pan by tightening 12 boltsto
