A manual intervention into the automatic shifting sequence is only then practical if the road
condition or the shape of the terrain is suitable.
Stopping and Parking:
Since due to the converter there is no rigid connection existing from the engine to the axle, it
is recommended to secure the vehicle on upgrades, resp. downgrades against unintended rolling
not only by applying the parking brake but additionally by a block on the wheel, if the
driver has the intention to leave the vehicle.
Oil temperature:
The oil temperature in the transmission sump is monitored by a temperature sensor in the
electrohydraulic control unit (64).
The service temperature in the sump of 60° - 90° C must not be exceeded (error indication
appears on the Display in the driver’s cabin) !
At a trouble-free unit and an adequate driving mode, a higher temperature will not occur. If
the temperature is rising above 90° C, the vehicle has to be stopped, controlled for external oil
loss and the engine must run with a speed of 1200 - 1500 min -1 at NEUTRAL POSITION of
the transmission.
Now, the temperature must drop quickly (in about 2 – 3 minutes) to normal values. If this is
not the case, there is a trouble pending, with must be eliminated prior to continue working.
Transmission control in the Driving mode Auto-
matic:
The supervision of the oil temperature behind the
converter is additionally realized with an
indication on the Display
Service temperature behind the converter at least
65° and 100° C in continuous operation, a
short-time increase (max. 5 minutes) up to max.
120° C is permitted.
The temperature will be measured on the measur
-
ing point 200 and showed at the instrument.
The maximally permitted permanent temperature
behind the Retarder is 145° C.
In exceptional cases, are short-time (max. 5 min
-
utes) 150° C permitted.
The temperature will be measured on the measur-
ing point 616 and transmit the signal to EST37.
