SERVICE ADJUSTMENT PROCEDUR&g
TRANSAXLE FLUID LEVEL INSPECTION
1. Drive until the fluid temperature reaches the usual tem-
perature [70-80°C

(160- 18O”F)I.
2. Place vehicle on level floor.
3. Move selector lever sequentially to every position to fill
torque converter and hydraulic circuit with fluid, then place
lever in “N” Neutral position.
4. Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the condition
of the fluid.
The transaxle should be overhauled under the following
conditions.
l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
l
If there is a noticeably great amount of metal particles in
the fluid.
5.Check to see if fluid level is in “HOT” range on dipstick. If
fluid level is low, add automatic transaxle fluid until level
reaches “HOT” range.
Transaxle fluid: DIAMOND ATF SP or equivalent
Low fluid level can cause a variety of conditions because it
allows pump to take in air along with fluid. Air trapped in hydraulic circuit forms bubbles which make fluid spongy.
Therefore, pressures will be erratic, causing delayed shift,
slippy clutch and brakes, etc.
Improper filling can also raise fluid level too high. When
transaxle has too much fluid, gears churn up foam and
cause the same conditions which occur with low fluid level, resulting in accelerated deterioration of automatic transaxle
fluid.
In either case, air bubbles can cause overheating, fluid
oxidation, which can interfere with normal valve, clutch,
and servo operation. Foaming can also result in fluid
escaping from transaxle vent where it may be mistaken for
a leak.
6. Be sure to examine fluid on dipstick closely.

TRANSFER OIL LEVEL INSPECTIONMm=xM
Transfer oil level inspection is the same as for the manual
transaxle transfer.

TRANSFER OIL REPLACEMENTM23FYAA
Transfer oil replacement is the same as for manual transaxle
transfer.

8. Engage the special tool (outer) on the locking nut.
Rotating the outer cyliner clockwise and the inner cylinder
counterclockwise, unlock the locking nut and special tool
(inner).
Caution
When unlocking the lock, apply equal force to both
tools.

9. Tighten the locking nut by hand until the locking nut
contacts the piston. Then, using the torque wrench, tighten
to the specified torque.
Locking nut: 25-32
Nm (18-23 ft.lbs.)
Caution
If it is rapidly tightened with the socket wrench or
torque wrench, the lock nut and adjusting rod may
rotate together.
10. Remove the special tool which fastens the piston.
Attach the plug to the outlet of the low reverse pressure.
LINE PRESSURE ADJUSTMENT
1. Drain out the automatic transaxle fluid.
2. Remove the oil pan.
3. Remove the oil filter.
4. Remove the oil-temperature sensor.

15. Tighten valve body assembly mounting.
Valve body assembly mounting bolts:11 Nm (8.0 ftlbs.)
A: 18 mm (.709
in.) long
B: 25 mm (.984
in.) long
C: 40 mm (1.575 in.) long
Caution (AWD)
Fix the solenoid valve and oil temperature sensor harness
securely in the position shown. Since the harness of the
pressure control solenoid valve (PCSV) is separately
provided from the other harness, route the former
harness as illustrated and clamp it. If clamping is
forgotten, it will come into contact with the detent plate and parking rod.
16. Install the oil filter.
17. Install a new oil pan gasket and oil pan.
18. Pour in the specified amount of Automatic transaxle fluid.
19. Make the oil pressure test. Readjust if necessary.
REDUCING PRESSURE ADJUSTMENTMZ3FTAb
(If the scan tool 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.

23-92AUTOMATIC TRANSAXLE - Service Adjustment Procedures
NOTE
When adjusting the reducing pressure, aim for the center
value (425 kPa, 60 psi) of the standard value allowance.
Standard value: 415-435
kPa (59-62 psi)
Oil pressure change for each turn of adjustment screw: 22
kPa (3.1 psi) . . . FWD (Up to MODEL 1990)
45
kPa (6.4 psi) . . . FWD (From MODEL 1990.5, AWD)
3. Install the oil filter and oil pan in the same way as for adjustment of the line pressure.
4. Make the oil pressure test. Readjust if necessary.
(If the scan tool is used)
1. Using the scan tool, forcibly drive the pressure control
solenoid valve at 50% duty, and measure the kick-down
brake apply pressure.
If the kick-down brake apply pressure does not exist within
the standard value width, adjust the pressure with the
reducing pressure adjustment screw.
Standard value: 275 + 10 kPa (39 + 1 psi)
Oil pressure change for each turn of adjustment screw:
25 kPa (3.6 psi) FWD (Up to MODEL 1990)
22
kPa (3.1 psi) FWD (From MODEL 1990.5), AWD
2. Check to be sure that the reducing pressure (after the
adjustment is completed) is within the range of 360-480
kPa (51 -68 psi.).
Caution
This adjustment should be made at an oil
temperature
of 70- 80°C
(160- 180°F).
If the adjustment is made at a temperature that is too
high, the line pressure will drop during idling, with the
result that it might not be possible to make the correct
adjustment.
