•
Dry the strainer thoroughly.
•
Clean the drain plug.
•
Inspect the washer and replace if necessary
Before checking the oil level or refilling, ensure that:
•
Vehicle is on level ground.
•
Lubricant temperature is between 20°C and 50°C.
•
Lubricant is at the level of the filler plug hole opening.
The oil drain intervals should be as per the OEM recommendation.
Refill the oil to the level of the filler opening. During oil refill, do not over fill. This causes the oil to be forced out
of the front and rear seals.
Do not mix different types of oil.
While adding the oil, it is recommended that different types and brands of oil are not intermixed because of
possible incompatibility.
WARNING
When filling with lubricant – Do Not Overfill. This causes oil to be forced out of the
front and rear seals.
2.4.1.8
Towing
Before towing the vehicle, place the transmission in neutral, and lift the rear wheels off the ground, or remove
the axle shafts, or disconnect the driveline to avoid damage to the transmission during towing
WARNING
Lift drive whiles off the ground or disconnect the driveline from the transmission to
avoid damage to the transmission during towing
2.4.2
Transmission Oil cooler
The vehicle manufacturer is responsible for providing the hardware and connections to the transmission for
cooling the transmission oil to ensure the oil is maintained within the specified temperatures of between 80
o
C –
100
o
C. The transmission bulk oil temperature should not exceed 120
o
C for more than 1 hour in any 12 hour
period. To enforce these requirements, the TCU will set the Transmission Temperature Warning signal (
Section
) when the transmission temperature reaches or exceeds 120
o
C. If the temperature stays at or above 120
o
C for 30min or reaches 125
o
C, the TCU will set the Transmission Temperature Error signal (
Section 7.3.2.23
) and
will limit torque production to 0 Nm. In addition, if the temperature reaches 120.5
o
C, the TCU will set the
Transmission Temperature Limiting signal (
Section 7.3.2.24
) signal and will reduce the maximum allowed torque
by 10% for each 0. 5
o
C rise in temperature above 120
o
C.
The transmission is equipped with an oil pump suitable to application of oil cooler. Oil cooler should be installed
as close to transmission as possible. 1 meter is reasonable distance. Actual length will depend on back pressure
created by cooler and hoses. Maximum back pressure of the system ( hoses + adapters) should be below
0.6bar (checked with motor speed corresponding to top vehicle speed).
Depending on operation conditions and availability of sufficient air flow to provide cooling, the customer may
find that the oil to air cooler is not needed (test in vehicle required).
