LINE PRESSURE TEST
Purpose of this test is to check operating conditions of each part
by measuring fluid pressure in fluid pressure line.
Line pressure test requires following conditions.
Automatic fluid is at normal operating temperature (70 –
80°C /158 – 176°F).
Fluid is filled to proper level (between FULL and LOW on
dipstick).
1) Apply parking brake securely and place chocks against
wheels.
2) Remove fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pressure check hole in
transmission case.
Special tool
(A) : 09925-37811-001
4) Depress foot brake fully, run engine at idle and stall then check fluid pressure in “D” or “R” range.
Line pressureCAUTION:
After attaching oil pressure gauge, check that no fluid
leakage exists.

CAUTION:
Do not continue running engine at stall speed longer than 5 seconds.

FLUID LEVEL AT ROOM TEMPERATURE
INSPECTION
The fluid level check at room temperature performed after repair
or fluid change before test driving is just preparation for level
check of normal operation temperature. The checking procedure
itself is the same as that described previously. If the fluid level is
between FULL COLD and LOW COLD, proceed to test drive. And
when the fluid temperature has reached the normal operating
temperature, check fluid again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) When engine has cooled down, remove drain plug (1) from
oil pan and drain A/T fluid.
3) Install drain plug.

INSTALLATION
1) Install shift solenoid valves.
Tightening torque
Solenoid valve bolts (a) : 8 N·m (0.8 kg-m, 6.0 lb-ft)
2) Connect shift solenoid couplers.
3) Install oil strainer (2) and transmission temperature sensor
(1).
Tightening torque
Transmission temperature sensor bolt
(b) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
4) Connect transmission temperature sensor coupler (3).
5) Clean mating surface of A/T oil pan (1) and A/T case.
6) Install new gasket (2) to A/T oil pan.
7) Install A/T oil pan.
Tightening torque
A/T oil pan bolts (a) : 7.5 N·m (0.75 kg-m, 5.5 lb-ft)
8) Install A/T fluid drain bolt.
Tightening torque
A/T fluid drain bolt (b) : 23 N·m (2.3 kg-m, 16.5 lb-ft)
9) Refill A/T fluid referring to “FLUID CHANGE” in this section.
10) Verify that there is no A/T fluid leakage.
NOTE:
Do not forget to install O-ring (4) to oil strainer first.

4) Remove output shaft speed sensor (1) and input shaft speed
sensor (2).
5) Remove transmission range sensor (3).
6) Remove dropping resistor (4).
7) Remove breather hose (5).
8) Remove A/T fluid level gauge (1) and filler tube (2).
9) Remove vehicle speed sensor (1) (for speedometer), shift
cable bracket (2) and connector clamp bracket (3).
10) Remove oil pan and oil pan gasket.
11) Remove oil strainer assembly (1), and detach transmission
temperature sensor (2).
NOTE:
 For removal of oil pan, do not turn transmission over
as this will contaminate valve body with foreign materi-
als in the bottom of oil pan.
 When removing oil pan, tap around it lightly with a
plastic hammer. Do not force it off by using a screw-
driver or the like.

58) Install O-ring to oil strainer assembly (1). Make sure that O-
ring is not twisted.
59) Install oil strainer assembly to the top of valve body assem-
bly.
Connect transmission temperature sensor (2) coupler.
Fix transmission temperature sensor and oil strainer assem-
bly with bolts.
