Transmission Fluid Level Inspection
Caution: Use Dexron VI
transmission fluid only. Failure to use the proper fluid may result
in transmission internal damage.
Note: Ensure the transmission
has enough fluid in it to start the vehicle safely without damaging
the transmission. With the vehicle off and the transmission fluid
temperature at approximately 20-25°C (68-77°F) there must
be at least enough fluid to drain out of the fluid level hole. This
will ensure that there is enough fluid in the sump to fill the
components once the vehicle is started.
Oil Level Checking Procedure
- Start the engine.
- Depress the brake pedal and move the gear lever
through each gear range, pausing for about 3 seconds in each range.
Then move the gear lever back to PARK (P).
- Allow the engine to idle 500-800 rpm for at least
3 minutes to allow any fluid frothing to dissipate and the
fluid level to stabilise. Release the brake pedal.
Caution: The transmission fluid
level must be checked when the transmission fluid
temperature (TFT) is at 85-95°C (185-203°F). If
the TFT is not at this temperature, operate the vehicle or allow
the fluid to cool as required. Setting the fluid level with a TFT
outside this temperature will result in either an under or
over-filled transmission. TFT over 95°C under-filled, TFT under
85°C over-filled. An under-filled transmission will cause
premature component wear or damage. An over-filled transmission
will cause fluid to discharge out the vent tube, fluid foaming, or
- Keep the engine running and observe the transmission
fluid temperature (TFT) using the Driver Information Centre or
a scan tool.
- Raise the vehicle on a hoist. The vehicle must be
level, with the engine running and the gear lever in the PARK
Warning: When the transmission is
at operating temperatures, take necessary precautions when removing
the check/fill plug, to avoid being burned by draining
Note: Drain the fluid into a
- While the vehicle is idling, remove the fluid level
plug (3). Allow any fluid to drain.
||If the fluid is flowing as a steady stream, wait
until the fluid begins to drip. Continue with step 14.
||If no fluid comes out, add fluid until fluid drips
out. Continue with step 7.
- Lower the vehicle.
- Remove transmission vent hose (2).
- Remove the transmission fluid filler
- While the vehicle is idling, add fluid through fluid
filler cap hole, until fluid is flowing as a stream out of fluid
level plug hole. Wait until the fluid drips out of fluid level plug
- Install the transmission fluid filler cap.
- Install the transmission vent hose.
- Raise the vehicle.
Caution: Refer to
Fastener Caution in the Preface
- Install the fluid level plug and tighten to
12 N·m (106 lb in)
- Lower the vehicle.
- Inspect for external leaks. Refer to
