Gearbox version:
1 (DIWA): No retarder in 1st gear; no auto-neutral on standstill (ANS)
2 (DIWA.2): Retarder present in 1st gear; with ANS, latency is either absent or fixed at designated latency period
3 (DIWA.3/.3E): No retarder in 1st gear; with ANS, latency is always present, but is 1 sec. shorter when a forward gear (1/2/3/D) is just selected
4 (DIWA.5): No retarder in 1st gear; with ANS, triggered whenever designated latency period is expired

The following curve determines the torque ratio of the torque converter.
X-axis is the turbine-to-impeller turns ratio, Y-axis is the torque ratio.
For example, the 1st gear of a majority of Voith DIWA gearboxes has a stall torque ratio of 5.05. Given the gear ratio of 1st gear is 1.36, the actual stall torque ratio is 3.713.

The below 4 curves set the threshold acceleration (in m/s^2) for changing the shifting points with respect to throttle applied.
Case 1 - SensoTop is enabled (continuous variation of shifting points):
- All 4 curves are used.
- When the acceleration is larger than threshold 1 (set in the 1st curve), economy mode is ON, shifting points at full throttle follow the smaller 'Max' one.
- When the acceleration is smaller than threshold 2 (set in the 2nd curve), full-power mode is ON, shifting points during kick-down is used at full throttle.
- When the acceleration is between thresholds 1 & 2, the shifting points vary linearly between economy & full-power shifting points according to acceleration.
Case 2 - SensoTop is disabled (2 discrete shifting modes only):
- Only threshold 1 is used, i.e. only the 1st & 3rd curves are used.
- When the acceleration is larger than the threshold, shifting points at full throttle follows the smaller 'MaxSpd_'.
- When the acceleration is smaller than the threshold, shifting points at full throttle follows the larger 'MaxSpd_Pwr'.
- Setting the same values for both 'MaxSpd_' & 'MaxSpd_Pwr' fully disables this function.

But, if SensoTop is enabled, the above curve sets the lower limit of torque governor ratio.
Then the actual torque governing ratio varies between the above lower limit & the maximum (= 1) according to acceleration.
If the acceleration is above the target (in m/s^2) below, the ratio is reduced until either the lower limit or the target is reached, whichever is greater.
If the acceleration is below the target, the ratio is raised until either the maximum (= 1) or the target is reached, whichever is smaller.

This sets the maximum turbine speed (in rpm) in 1st gear of which throttle delay is activated:

[const]
antrieb_getr_n_ab_max_ThrottleDelay

The throttle delay in the 1st gear is dependent on the time (in sec) of applying throttle.
Reducing throttle resets the timer to zero.

This throttle delay is activated when the gearbox shifts down from 2nd to 1st gear to prevent gear slipping.
Principles are same as the above one, except that this throttle delay sets in when the turbine speed is above the limit set in the constant "antrieb_getr_n_ab_max_ThrottleDelay".
