WARNING:
For vehicles equipped with a Supplemental Restraint (Air Bag) System:
• Service on and around the air bag system components or wiring must be performed only by an
authorized Holden dealer. Refer to “System Components and Wiring Location View and
Connectors” under “General Description” in Section 10B in order to confirm whether you are
performing service on or near the air bag system components or wiring. Please observe all
WARNINGs and “Service Precautions” under “On-Vehicle Service” in Section 10B before
performing service on or around the air bag system components or wiring. Failure to follow
WARNINGs could result in unintentional activation of the system or could render the system
inoperative. Either of these two conditions may result in severe injury.
• Technical service work must be started at least 90 seconds after the ignition switch is turned to
the “LOCK” position and the negative cable is disconnected from the battery. Otherwise, the
system may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the items not listed below, refer to the Section 7B.

Automatic Gear Shift Diagram
Automatic shift schedule as a result of shift control is shown below. In case that selector lever is shifted to “L”
range at a higher than 46 km/h (29 mile/h) speed, 2nd gear is operated and then down shifts to 1st at a speed
lower than that.
The same as, the select lever is shifted to “2” range at a higher than 92 km/h (57 mile/h) speed, 3rd gear is oper-
ated and then down shifts to 2nd at a speed lower than that.

Manual Road Test
This test checks the gears being used in “L”, “2” or “D” range
when driven with unoperated gear shift control system. Test drive
vehicle on a level road.
1) With select lever in “P”, start engine and warm it up.
2) After warming up engine, turn ignition switch OFF and dis-
connect valve body harness connector (1).
3) With select lever in “L” range, start vehicle and check that 3rd
gear is being used referring to table shown below.
Vehicle speed per 1000 rpm in engine speed (V1000 table,
reference)
4) While vehicle is running, shift select lever to “2” range and
check that 3rd gear is being used.
5) While vehicle is running, shift select lever to “D” range and
check that 3rd gear is being used.
6) After above checks, stop vehicle then turn ignition switch
OFF, and connect valve body harness connector.
7) Clear DTC.
Troubleshooting
NOTE:
Before this test, check diagnostic trouble code (DTC).

Condition Possible Cause Correction
Operated gear is not
correct
Faulty valve body component Replace valve body assembly.
Faulty clutch or brake Inspect clutch and brake. If any
parts are faulty, replace them.
