AUTOMATIC TRANSMISSION (4L30–E)

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).

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 kg·m/28 Ib 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

(90

F) and 57

C (135

F) 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 kg·m/28 Ib 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 Connection in Transmission
Control System (4L30-E) section.

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

secure it (using a rubber band (3), etc.) so that the pin
comes into contact with the wall of the detent plate.

5. Install the shift control rod (1) to the selector lever arm

(4).

Torque: 32 N

•

m (3.3 kg·m/24 Ib 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 (3.8 kg·cm/33 Ib in)

NOTE: Clean the cable threads, and do not apply oil to
them.

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.
