The transmission overload protection function protects the shift elements of the automatic transmission (722.6) from excessive thermal stresses during load changes in the upper engine speed range.
Engine torque is reduced by briefly retarding the ignition and closing the throttle valve, reducing charge pressure during gearshifts.
The ME-SFI control unit (N3/10) is supplied with a signal via the CAN databus by the ETC control unit (N15/3) for this purpose.
The ME control unit controls in line with the performance map, if altering the ignition angle is sufficient or if the throttle valve must be retarded.
