. 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

= 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.

11.4 DIAGNOSIS AND TESTING
' 11.4.1 Tire Wear
Tires should be inspected as abnormal or excessive wear may becaused by incorrect wheel alignment, wheelbire im- balance, or incorrect tire pressure.
1 1.4.2 vibration and Roughness
Vibration, roughness, and shimmy conditions may be caused by excessive tire or wheel runout, worn or cupped tires,
or wheel and tire unbalance.
Most of these conditions are due to irregularities in the road surface, hence driving the vehicle on different types of
road surface will often indicate the cause of the condition.
Do not automatically suspect the tires when attempting to diagnose a vibration concern as other sources of vibration
Before investigating any other vibration concerns,
a roaG &est and a customer inter\,.dw (if possible) should be carried
out. This can provide much of the information needed to find the source of vibration.
Drive the vehicle on a road that is preferably smooth and free of undulation and
if vibration is apparent note, the speed at which thevibration occurs, whattype of vibration occurs in each speed range (mechanical or audible), howthevibra- tion is affected by changes in vehicle speed , engine speed and engine torque, and the type of vibration sensitivity
(torque sensitive, vehicle speed sensitive, or speed sensitive).
Some of the condition terms used when describing sources of vibration are explained as follows:
0 Torque Sensitive
This condition can be improved or worsened by accelerating, decelerating, coasting, maintaining
a steady
vehicle speed and application of engine torque.
0 Vehicle Speed Sensitive
This means that the vibration always occurs at the same vehicle speed and is not affected by engine torque,
engine rpm, or transmission gear selection.
B
0 Engine Speed Sensitive
This means that the vibration occurs
at varying vehicle speeds when a different transmission gear is selected.
It can sometimes be isolated by increasing or decreasing engine speed with the transmission in 'NEUTRAL', or
by stall testing with the engine in gear. If the condition is enginesensitive, the condition is not related to tires.
If the road tests indicates that the vibration is related to the tires or wheels,use a 'lire Wear Diagnosis Chart' to
investigate the cause of concern. Should the road test indicate that there is tire whine, but noshake or vibration,
the noise originates from the contact between the tire and the road surface.
