. Raise the vehicle on a ramp.
. Position a drain tin below the transmission unit.
. Release and remove the fluid pan drain plug.
. Allow the fluid to drain.
Clean the drain plug, including the magnet and the fluid
pan drain plug face.
. Fit and tighten the fluid pan drain plug.
. Remove the drain tin from below the transmission unit.
. Lower the vehicle on the ramp.
Open the hood and fit
a suitable fender cover.
Remove and wipe the dipstick.
. Fit a funnel to the dipstick tube.
. Initially fill the transmission with 4,5 liters of fluid.
. Remove the funnel.
. Open the front door.
. Check that the parking brake is applied.
. Start the engine.
Apply the footbrake.
Run the shift lever through all positions, finally returning
to the Park position.
. Release the footbrake.
. Insert the dipstick, then remove and inspect the level.
. Fit the funnel to the dipstick tube.
. Fill the transmission to the 'COLD' level mark on the dip-
stick with the correct fluid, see the Powertrain Automatic
Transmissions Service Manual, General Data.
CAUTION: On no account should the vehicle be driven un- less the fluid level is at the 'COLD' level and the
system primed.

Remove the funnel.
. Replace the dipstick.
. Switch the ignition OFF.
. Remove the fender cover and close the hood.
= Close the door.
J&&Q: 0 After road testing the vehicle, the fluid level on the
dipstick should be between the 'HOT' Min I Max
marks. Check the level with the transmission at nor-
mal operating temperature (90 to 100°C), with the
engine left running and the transmission in the Park
position.
