AUTOMATIC TRANSMISSION (4L30–E)
Chart 16: Possible Causes Of
Transmission Fluid Leaks
Before attempting to correct an oil leak, the actual source
of the leak must be determined. In many cases, the
source of the leak may be difficult to determine due to
“wind flow” around the engine and transmission.
The suspected area should be wiped clean before in-
specting for the source of the leak.Oil leaks around the engine and transmission are gener-
ally carried toward the rear of the vehicle by the air
stream. In determining the source of an leak, the following
two checks should be made:
1. With the engine running, check for external line
pressure leaks.
2. With the engine off, check for oil leaks due to the
raised oil level caused by drainback of converter oil
into the transmission.

Stall Test
The stall test allows you to check the transmission for
internal abrasion and the one way clutch for slippage.
Torque converter performance can also be evaluated.
The stall test results together with the road test results will
identify transmission components requiring servicing or
adjustment.
Stall Test Procedure:
1. Check the level of the engine coolant, the engine oil,
and the automatic transmission fluid. Replenish if
necessary.
2. Block the wheels and set the parking brake.
3. Connect a tachometer to the engine.
4. Start the engine and allow it to idle until the engine
coolant temperature reaches 70 – 80
C (158 –
176
F).
5. Hold the brake pedal down as far as it will go.
6. Place the selector in the “D” range.
7. Gradually push the accelerator pedal to the floor.
The throttle valve will be fully open.
Note the engine speed at which the tachometer
needle stabilizes.
Stall Speed : 2,100
150 rpm
NOTE: Do not continuously run this test longer than 5
seconds.
8. Release the accelerator pedal.
9. Place the selector in the “N” range.
10. Run the engine at 1,200 rpm for one minute.
This will cool the transmission fluid.
11. Repeat Steps 7 – 10 for the “3”, “2”, “L” and “R”
ranges.
Line Pressure Test
The line pressure test checks oil pump and control valve
pressure regulator valve function. It will also detect oil
leakage.
Line Pressure Test Procedure:
1. Check the level of the engine coolant, the engine oil,
and the automatic transmission fluid.
Replenish if required.
2. Block the wheels and set the parking brake.
3. Remove the pressure detection plug at the left side of
the transmission case.
Set 5–8840–0004–0 pressure gauge and adapter to
the pressure detection plug hole.
241RS001
4. Start the engine and allow it to idle until the engine
coolant temperature reaches 70 – 80
C (158 –
176
F).
5. Hold the brake pedal down as far as it will go.
6. Place the selector in the “D” range.
7. Note the pressure gauge reading with the engine
idling.
8. Gradually push the accelerator pedal to the floor. The
throttle valve will be fully open.
Note the pressure gauge reading with the accelerator
pedal fully depressed.
NOTE: Do not continuously run this test longer than 5
seconds.
9. Release the accelerator pedal.
10. Place the selector in the “N” range.
11. Run the engine at 1,200 rpm for one minute.
This will cool the transmission fluid.
12. Repeat Steps 7 – 11 for the “3”, “2”, “L”, and “R”
ranges.
13. Install a pressure detection plug to the transmission
case, applying recommended thread locking agent
(LOCTITE 242) or its equivalent to thread of plug.
Make sure that thread is cleaned before applying
locking agents.
14. Tighten the pressure detection plug to the specified
torque.

Changing Transmission Fluid
There is no need to change the transmission fluid unless
the transmission is used under one or more of the
following heavy duty conditions.
A. Repeated short trips
B. Driving on rough roads
C. Driving on dusty roads
D. Towing a trailer
If the vehicle is used under these conditions, change the
fluid every 20,000 miles (32,000 km).
More over, the remaining life percentage of ATF can be
estimated by using Tech 2 as an auxiliary tool to judge the
right time for ATF replacement.
The remaining life percentage is calculated from ATF’S
heat history. When it is close to 0%, ATF replacement is
recommended.
1. Place a large drain pan under the oil pan.
2. Remove the transmission oil drain screw (2) and drain
fluid.
3. Tighten drain screw (2).
Torque: 38 N
m (3.9 kgꞏm/28 lb ft)
4. Remove the transmission overfill screw (1) and fill
transmission through overfill screw opening, using
DEXRON
–III ATF.
NOTE: Add transmission fluid until it flows out over the
overfill screw opening.
5. Let engine idle until a fluid temperature between 32
C
(90
F) and 57C (135F) is reached.
6. Add transmission fluid until it flows out over the overfill
screw opening, then close the overfill screw (1).
Torque: 38 N
m (3.9 kgꞏm/28 lb ft)NOTE: To prevent fluid leaks, the overfill screw and oil
drain screws gasket must be replaced each time these
screws are removed.
NOTE: Check transmission fluid temperature with
service scan tool.
7. Reset “Oil Life Monitor” data by using Tech 2.
Refer to Tech 2 OBD II Connector in Transmission
Control System (4L30-E) Section.

Selector Lever
Inspection
1. Make sure that when the selector lever is shifted from
“P” to “L”, a “clicking” can be felt at each shift position.
Make sure that the gear corresponds to that of the
position plate indicator.
2. Check to see if the selector lever can be shifted as
shown in illustration.

Removal
1. Disconnect battery ground cable.
2. Remove transfer control lever knob.
3. Remove front console.
Disconnect wiring harness connectors from front
console.
4. Disconnect shift lock cable (1) from the selector lever
assembly side.
256RW012
5. Disconnect shift control rod (2) from the selector lever
assembly side.
256RW013
6. Disconnect wiring harness connectors from the
selector lever assembly.
7. Remove selector lever assembly.
Installation
To install, follow the removal steps in the reverse order,
noting the following points:
Adjustment of select lever and control rod
1. Place the vehicle on a level surface.
NOTE: If the vehicle is not on level surface, the shift
select cable set positions will vary with the movement of
engine. To prevent possible misadjustment of the cable,
the vehicle must be placed on a level surface.
2. Install the shift control rod (1) to the transmission
select lever (2), and then place the lever in the “N”
position.
3. Set select lever in the “N” position.
4. Push select lever forward (“R” position side) and
s e c u r e i t ( u s i n g a r u b b e r b a n d ( 3 ) , e t c . ) s o t h a t t h e p i n
comes into contact with the wall of the detent plate.
5. Install the shift control rod (1) to the selector lever arm
(4).
To r q u e : 3 2 N
m (3.3 kgꞏm/24 lb ft)
NOTE: Do not apply oil to the threaded portions.
256RW014
6. After adjustment, make sure that the selector lever
operates normally, and that each selector position is
properly indicated. (The red mark shows through the
window.)
Adjustment of shift lock cable
1. Set ignition key in “LOCK” position and selector lever
in “P” position.
2. Adjust cable screw cap on selector lever side to
provide a gap (slack for cable) of 1 – 2 mm between
rod on steering lock side and stopper.
Adjust cap as follows:
a. Pull screw cap (1) in arrow direction to remove
inner cable slack.
b. With cable kept as (a), adjust gap between nut (2)
and bracket to 5 mm (0.2 in).
c. Lock inner cable by turning nut (3) while holding nut
(2) in place.
Torque : 3.7 N
m (38 kgꞏcm/33 lb in)

7A–31 AUTOMATIC TRANSMISSION (4L30–E)
NOTE: Clean the cable threads, and do not apply oil to
them.
256RW015
3. Check the shift lock operation:
a. Selector lever should not move out of “P” position
with ignition key in “Lock” position.
b. Selector lever can be moved out of “P” position with
ignition key in “ON” position only when brake pedal
is depressed.
c. Ignition key can be turned to “LOCK” position only
when selector lever is in “P” position (key can be
pulled out).
If (a) and (c) fail, readjust cable. If (b) fails, readjust
connector wiring and brake pedal switch.
Mode Switch
Removal
1. Place selector lever in neutral.
2. Disconnect battery ground cable.
3. Remove mode switch cover (1).
4. Disconnect selector lever (2) from the mode switch.
5. Disconnect transmission harness from the mode
switch connector (3).
6. Remove bracket with mode switch connector from
the transmission case.
7. Remove mode switch connector (3) from the bracket
(4).
8. Remove two mode switch bolts and nut then remove
mode switch (5).
