Hot Oil Level Check - Engine Running
This hot check is valid for normal operating oil
temperature of 80° C (176° F).
1. Position the vehicle on a level work area, apply the
parking brake and block all road wheels securely.
2. With the transmission in neutral and the engine
running, allow the machine to idle until normal operating
temperature of 80° C (176° F) is achieved.
3. With parking brake applied, foot on service brake,
engine idling and transmission operating at normal
temperature, select each gear position in turn. Allow
the transmission to remain in each gear for 5 - 10
seconds.
4. Return gear selector to neutral and, with the engine
idling, check the oil level on dipstick. Oil level should
be between the 'MAX 80° C' upper mark and the 'MIN
80° C' lower mark on the dipstick. Add oil if low.
Oil and Filter Change
After the first 500 hours of operating a new or rebuilt
transmission, the transmission oil and filter cartridges
(16, Fig. 9) should be changed. Internal filter and finger
magnet at the lower front left hand of the sump should
be removed and cleaned.
The transmission oil and filter cartridges should be
changed every 1 000 hours, or sooner, depending on
operating conditions. Clean oil filter head (15, Fig. 9)
when changing filter cartridges (16, Fig. 9). Also, the oil
must be changed whenever there are traces of dirt or
evidence of high temperature indicated by discoloration
or strong odour.
The internal filter and finger magnet at the lower front
left hand of the sump should be removed and cleaned
with mineral spirits at each oil and filter change. Metal
particles in the oil (except for the minute particles
normally trapped in the oil filters) indicate damage has
occurred in the transmission. When these particles are
found in the filters, the cause must be established and
rectified immediately to prevent damage to the
transmission.
At each oil change, examine the used oil for evidence
of dirt or water. A normal amount of condensation will
emulsify in the oil during transmission operation.
However, if there is evidence of water or engine coolant
in the oil, the cause must be established and rectified
immediately to prevent damage to the transmission.
AEB Starter
The AEB Starter is an electronic tool used to calibrate
the transmission to ensure optimum shift comfort. It is
recommended to run the AEB Starter after the first 500
hours of transmission operation. The AEB Starter
should also be run if shift quality deteriorates, or
whenever the transmission, electronic control unit
(ECU) or shift lever are replaced. The procedure for
running the AEB Starter is detailed in the table on the
following page. Refer to table on page 10 for typical
codes displayed during AEB mode.
Note: Connect the AEB Starter to plug X25 located
below the right hand dash panel, adjacent to the ECU.
TROUBLESHOOTING
Numbers in parentheses refer to Fig. 2, unless
otherwise specified. Refer to Fig. 11 for plug
identification.
Transmission Sensor Checks
The engine (5), turbine (8), central gear train (7) and
output (6) speed sensors can be checked by
measuring their resistance at plug X8 (located below
the dash panel).
1. Engine speed sensor (5). Check across pins 1 & 2.
Resistance should be 945 - 1 155 ohms at a
temperature of 20° C (68° F).
2. Turbine speed sensor (8). Check across pins 3 & 4.
Resistance should be 945 - 1 155 ohms at a
temperature of 20° C (68° F).
3. Central gear train speed sensor (7). Check across
pins 5 & 6. Resistance should be 945 - 1 155 ohms at
a temperature of 20° C (68° F).
4. Output speed sensor (6). Check across pins 21 &
22. Resistance should be 5 mega ohms.
The installation of the speed sensors can also be
checked by measuring the gap between the sensor and
the gear tooth:
