Push-button Check - (Electronic
Transmission Fluid Level Check)
The electronic method of checking the transmission
fluid level incorporates a fluid level sensor to display
the fluid level on the shift selector.
The electronic method compensates for transmis-
sion fluid temperature between 65°C to 104°C
(149°F to 220°F). Any temperature below 65°C
(149°) or above 104°C (220°F) will result in an Inva-
lid for Display condition.
The normal operating temperature of the transmis-
sion fluid is 71°C to 93°C (160°F to 200°F),
measured at the transmission sump .
The reading obtained on the digital analogue will
show the temperature measured at the transmission
convertor out . Note that this temperature is normally
higher than the sump temperature.
The following procedure must be used to check the
transmission fluid level using the push-button shift
selector:
1. Ensure that the machine is parked on a level
surface and the park/emergency brake is ap-
plied.
2. Allow the engine to run at idle in N (Neutral).
3. Press the ↑ (UP) and ↓ (DOWN) arrow buttons
(1) simultaneously.

Note: The fluid level check may be delayed until the
following conditions are met:
• The fluid temperature is above 65°C (149°F)
and below 104°C (220°F).
• The transmission is in neutral.
• The machine has been stationary for approxi-
mately two minutes to allow the fluid to settle.
• The engine is at idle.
• The transmission output shaft is stopped.
Note: The indication of a delayed fluid level check is
a flashing display and a digital countdown from 8 to
1.
4. Check the characters displayed.
5. The fluid level information is sequentially dis-
played on the digital analogue as in the following
examples:
Correct Fluid Level
1. "O" then "L" are displayed ("OL" represents
'Fluid (oil) Level Check Mode), followed by "O"
then "K". The "OK" display indicates the fluid is
within the "OK" zone. The sensor display and
the transmission dipstick may not agree be-
cause the oil level sensor compensates for fluid
temperature.
Low Fluid Level
1. "O" then "L" are displayed ("OL" represents
'Fluid (oil) Level Check Mode), followed by "L"
then "O" ("LO" represents Low Oil Level) and the
number of quarts that the transmission fluid is
low e.g. "0" then "2" indicates 2 additional
quarts/litres of fluid will bring the fluid level within
the middle of the "OK" zone.
Note: 1 quart is approximately equal to 1 litre.
High Fluid Level
1. "O" then "L" are displayed ("OL" represents
'Fluid (oil) Level Check Mode), followed by "H"
then "I" ("HI" represents High Oil Level) and the
number of quarts that the transmission is over-
filled e.g. "0" then "1" indicates 1 quart/litres of
S005090
fluid above the full transmission level.
2. Replenish or drain the transmission fluid as re-
quired.
Chapter 10 - Change the Transmission Fluid
and
Filter.
Note: The maximum Low Oil level and High Oil level
values are "04". If the transmission fluid level is lower
or higher than 4 quarts/litres, the fluid level will have
to be checked twice to obtain the correct reading.
3. If a condition occurs which prevents the display
of fluid level information, the Invalid for Display
will show the reason as follows:
