The�BMW3�SeriesLCI�features�a�new�engine�generation�6�cylinder�engine�with�a�modular�design
(Bxx).
In�adopting�the�new�engine�generation,�certain�model�designations�have�also�been�changed:
• The�BMW335i�is�now�the�BMW�340i
(with�an�increase�in�performance�from�300�hp�to�326hp)

3.2.2.�Engine�speed�adaptation�for�a�gear�change
During�a�gear�change�the�engine�speed�is�automatically�adapted�to�the�new�transmission�ratio.�The
engine�and�the�transmission�input�shaft�have�the�same�speed�when�engaging�the�clutch.�This�ensures
the�clutch�is�always�engaged�smoothly.

Index Explanation
1 Gear�sensor
2 Magnetic�clip
3 Gearshift�shaft
3.2.3.�Gear�sensor
In�the�3�series�LCI�manual�transmission�a�gear�sensor�is�used,�which�detects�the�correct�position�of�the
individual�gears�as�well�as�the�neutral�position.�This�information�is�transmitted�to�the�DME�.
A�mechanical�reverse�gear�switch�is�no�longer�required.
There�is�a�magnetic�clip�secured�on�the�gearshift�shaft.�The�alignment�of�the�magnetic�field�lines�of�the
magnetic�clip�are�evaluated�by�the�gear�sensor,�which�is�screwed�to�the�transmission�housing�from�the
outside.
The�‘3D�magnetic�field�sensor�system”�is�integrated�in�the�gear�sensor.�This�type�of�gear�sensor
measures�magnetic�fields�which�are�aligned�parallel�to�the�chip�surface.�This�ensures�that�every�gear
shift�and�engaged�gear�is�recognized.
The�sensor�is�capable�of�self-diagnosis�and�can�input�a�fault�in�the�system.

The�information�from�the�neutral�sensor�is�also�used�for�the�MSA�function�as�well�as�the�shift�point
indicator,�and�engine�speed�adaptation�during�a�gear�change.
The�corresponding�engine�speed�is�calculated�by�the�DME�and�held�for�a�maximum�of�2�seconds.
The�engine�speed�is�adapted�in�varying�degrees�depending�on�the�driving�mode�selected.
For�the�control�the�clutch�pedal�must�be�fully�pressed�when�shifting.
The�engine�speed�adaptation�for�the�gear�change�is�not�active:
• When�the�DCS�is�switched�off
• At�driving�speeds�<�12�mph
• When�switching�to�1st�gear
The�engine�speed�adaptation�can�be�permanently�deactivated�by�the�diagnosis�system.
After�replacement�of�the�sensor�it�must�be�calibrated�with�the�BMW�diagnosis�system.
3.3.�Automatic�transmission
The�new�GA8HP50Z�automatic�transmission�is�used�in�the�BMW3�SeriesLCI�with�the�new�engine
generation�(B58).�This�is�a�further�development�of�the�already�established�automatic�transmission
GA8HP45Z�used�with�the�N20�and�N26�engines..
It�is�characterized�above�all�by�improved�efficiency�as�well�as�enhanced�driving�and�shifting�comfort.
These�improvements�have�been�achieved�by�the�following�measures,�to�name�a�few:
• Greater�spread�thanks�to�two�changed�gear�sets
• Mechanical�disc�separation�by�undulated�expander�springs�in�brakes�A�and�B�in�the�not
actuated�state
• Additional�spring�assembly�for�the�opening�of�brake�B.

3.3.2.�ConnectedShift
ConnectedShift�uses�navigation�data�for�a�forward-thinking�shift�strategy�of�the�automatic
transmission.�If,�for�example,�a�sharp�curve�is�detected�ahead,�the�automatic�transmission�shifts
down�early�and�the�gear�is�retained�in�the�bend.
The�route�guidance�of�the�navigation�system�does�not�need�to�be�activated�for�the�function.�However,
the�identification�of�a�turn-off�request,�for�example�by�the�active�route�guidance�or�operation�of�the�turn
indicator,�helps�to�control�the�system�more�accurately.�Up-to-date�navigation�map�data�also�influences
the�control�accuracy.
