Emergency program

The emergency program is activated on failure of the transmission control or on detection of faults that lead to critical driving states. In the emergency program, the vehicle can still be driven with certain restrictions.

There are two different types of emergency program:

Hydraulic emergency program 

In the event of failure of an electrical component, the transmission can switch into the hydraulic emergency program. In this case, all the solenoid valves are switched off and the transmission shifts, if the 1st, 2nd or 3rd gear is engaged, permanently into 3rd gear.

If the 4th, 5th or 6th gear is engaged in the event of failure of the electrical equipment, the transmission shifts permanently into 5th gear.

When the transmission is operating in the emergency program, 5th gear is engaged and the ignition is switched of and on again, the transmission shifts to 3rd gear.

Electrical emergency program 

If a gripping clutch does not correctly engage or the releasing clutch does not correctly disengage, the transmission control can switch into the emergency program. The transmission works in the restricted mode. Defective clutches are not used. This means that only a limited number of gears is available.

No liability can be accepted for printing or other faults. Subject to changes of a technical nature
