Automatic transmission with Steptronic

The ATC will execute upshifts or down-
shifts only at appropriate engine and
road speeds. For example, the trans-
mission does not shift down when the
engine speed is too high. The selected
gear will appear briefly in the instrument
cluster, followed by the current gear.
In the manual mode for rapid ac-
celeration – when passing, for ex-
ample – manually or a shifting down to
the kickdown point.

You can only change from M/S to the
selector lever positions "P," "R" and "N"
via the "D" position.
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
> In order to prevent engine over-
speeding, the transmission shifts au-
tomatically to the next higher gear
shortly before the RPM cutoff point
> At low speeds, the transmission shifts
down automatically - you do not have
to act
> In the kickdown mode, the transmis-
sion shifts down to the lowest gear
which is possible, depending on the
engine speed.
Electronic transmission control
module
If the "TRANS. FAILSAFE PROG" mes-
sage appears in the Check Control,
there is a malfunction in the transmis-
sion system.
You can still place the selector lever in
all positions. However, it is possible
that not all gears are available for the
vehicle's forward drive.
If this happens, avoid extreme engine
loads and consult the nearest autho-
rized BMW center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do
this, the vehicle could move.
