7A±27 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 Nwm (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 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 Nwm (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 scan
tool.
7. Reset ªOil Life Monitorº data by using Tech 2.
Refer to
Tech 2 OBD II Connection in Transmission
Control System (4L30-E) section.

Selector Lever
Inspection
1. Make sure that when the selector lever is shifted from
ªPº to ªLº, a ªclickingº 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. Set ignition Key in ªLOCKº position and selector lever
in ºPº position.
3. Remove knee pads (1), cluster upper cover (2) and
center cluster assembly (3).

Diagnostic Trouble Codes
The purpose of the ªDiagnostic Trouble Codesº mode is to
display stored PCM trouble codes.
When ªDiagnostic Trouble Codesº is selected an
ªApplication Menuº screen appears.
Clear DTC Information
The purpose of the ªClear DTC Informationº mode is to
command the clearing of stored PCM trouble codes.
When ªClear DTC Informationº is selected, a ªClear DTC
Informationº, warning screen appears. This screen
informs you that by cleaning DTC's, ªall stored DTC
information in controller will be erasedº.
Do you want to clear DTC's (Yes/No).
Press either the Yes or No key when answering.
After clearing codes, confirm system operation by test
driving the vehicle.
Allow the vehicle to shift through all four forward gears in a
manner which attempts to repeat the failure condition.
NOTE: When the trouble has not been repaired and the
trouble code cannot be erased, check the vehicle again.
DTC Information
When ªDTC Informationº is selected, an ªApplication
Menuº appears with a list of DTC information function
keys addressing DTC specifics and their origins.
Function key selections may vary for particular vehicle
and/or system.
Data Display
The purpose of the ªData Displayº mode is to
continuously monitor data parameters.
The current actual values of all important sensors and
signals in the system are display through F1 mode.
When ªData Displayº is selected an ªApplication Menuº
appears. Please select either ªEngineº or ªTransmission
Data Displayº.
See ªTransmission Dataº on next page.
Snapshot
When ªSnapshotº is selected an ªApplication Menuº
appears.
When ªTransmission Snapshotº application is selected
from the ªApplication Menuº, a ªSnapshot Menuº
appears, displaying several options. ªSnapshotº options
may vary from one system to another.
ªSnapshotº allows a recording of all vehicle parameters.
There parameters may then be replayed at a future point
in time.
This action allows you to focus on making the condition
occur, rather than trying to view all of the data in
anticipation of the fault. The snapshot will collect
parameter information around a trigger point that you
select.
When a snapshot is taken. It is recorded onto the
PCMCIA memory card. When the Tech 2 is powered
down. Snapshots are not lost.
Actuator Tests
The purpose of ªActuator Testsº mode is to check for
correct operation of electronic system actuators.Lamps
You can operate the lamps by pressing the ON and OFF
buttons.
Preconditions: none
Solenoid
Solenoid 1-2/3-4, Solenoid 2-3, TCC Solenoid
You can operate the solenoids by pressing the ON and

You can operate the solenoid by pressing the ON and
OFF buttons.
Preconditions: P-N position, idle engine speed, no vehicle

Pressure Control Solenoid (PCS)
You can set desired PCS Current using the ªIncrementº

Data informs about PCS Current, Pressure and Duty
Cycle.
Preconditions: P±N position, no engine speed, no vehicle
speed
Reset Oil Life Monitor
Displays parameter ªOil Life Monitorº and resets to 100%
if Yes-button is pressed on Reset-question. ªNoº leaves
test.
Preconditions: no vehicle speed, no engine speed
NOTE:
Freeze Frame (Powertrain DTC A/B Type)
Freeze Frame is an element of the Diagnostic Manage-
ment System which stores various vehicle information at
the moment an emissions-related fault is stored in
memory and when the MIL is commanded on. These data
can help to identify the cause of a fault. Refer to
Storing
And Erasing Freeze Frame Data
for more detailed in-
formation.
Failure Records (Powertrain DTC C/D Type)
Failure Records data is an enhancement of the OBD II
Freeze Frame feature. Failure Records store the same
vehicle information as does Freeze Frame, but it will store
that information for any fault which is stored in on-board
memory, while Freeze Frame stores information only for
emission-related faults that command the MIL on.

When diagnosing for an intermittent short or open
connection, move the wiring harness while watching
the test equipment for a change.

First diagnose and clear any engine DTCs or TP
Sensor codes. Then inspect for any transmission
DTCs that may have reset.Test Description
The number below refers to the step number on the
diagnostic chart:
3. This test checks PCM and associated wiring up to
the 7±way connector. If the voltage increases to
match chart the problem is isolated to the
transmission wiring.

Removal
1. Disconnect the battery ground cable.
2. Remove the MID control unit (3).

Refer to
MID (1) in this section.

Remove the control unit (3) from the bracket (2).
CAUTION: When the battery is disconnected, the
MID control unit directional data is lost (the control
unit returns to its start-up condition). When the
battery is reconnected, the display will be erroneous
until the control unit receives a clear GPS satellite
signal and resets its directional data.
After reconnecting the battery, wait until the satellite
mark indicator turns on. Select an area where there
are no high buildings or other obstacles to electro-
magnetic waves. Drive the vehicle in a straight line at
a speed exceeding 32 km/h (20 mph) for at least 20 se-
conds.
