filled with oil.
NOTE:
After completing the preparation, proceed to the actual
transmission fluid level check.
CAUTION:
Only continue with the fluid level check if the transmission
temperature is between 35ºC (95ºF) 45ºC (113ºF).
- Start the engine, if not already idling.
- Maintain the engine idle speed.

CAUTION:
Drain the fluid into a suitable container.
- Remove the transmission fluid level plug, do not discard.
CAUTION:
Transmission fluid temperature must not exceed 45ºc (113ºF).
NOTE:
With the engine running a small amount of automatic
transmission fluid should trickle out of the transmission fluid
level plug hole.
- If fluid flows out, proceed to step 13.
- If fluid does not flow out, proceed to step 12.
- If the transmission fluid does not come out of the
transmission fluid level plug hole the transmission fluid level
is insufficient. If this is the case add the transmission fluid in
100 millilitre units into the transmission fluid level plug hole
using a suitable syringe.
General Equipment: Oil syringe
- Allow the transmission fluid to drain from the transmission
fluid level plug hole until the flow almost stops to a trickle.
Install the original transmission fluid level plug.
Torque: 35 Nm
Switch off the engine.
