Adaptive shifting programs

Adaptive shifting programs

Adaptive shifting programs are selected automatically depending on the engine load. The function is available in the normal program.

Shifting occurs at higher engine rpms and the gear is engaged for longer if the control module senses that the load does not decrease. These shifting programs are in place to avoid unnecessary up and downshifting, for example when driving on long uphill grades with a trailer, and also to avoid overheating the transmission fluid.

Adaptive shifting programs are selected automatically if the transmission fluid overheats, in order to prevent the transmission from becoming seriously damaged, and to lower the temperature of the gearbox. Programs are activated when the temperature exceeds 150 °C. Lock-Up is then engaged in 2nd gear, preventing slip.

The adaptive shifting programs are not activated at speeds above 150 km/h. If an adaptive shifting program is active when the speed increases to above 150 km/h, the program is maintained until the control module senses that a more suitable shifting pattern can be activated.


Adaptive shifting programs are disengaged if:



• Sport or Winter programs are selected.

• the ignition switch is turned to the ON or OFF position

• The load or temperature reduces to such an extent that the adaptive shifting pattern is no longer needed.

• CHECK GEARBOX lamp lights up.
