TCT TWIN CLUTCH
TRANSMISSION
Alfa 4C features the TCT 6-speed twin
dry clutch transmission with steering
wheel controls. This is an advanced
technical solution which combines the
control of a manual gearbox, the
immediacy of a sequential system and
the convenience of being able to select an
automatic selection programme without
the slowdown of a conventional
automatic transmission.
With the key removed from the ignition,
the system will not implement any action
when the buttons on the transmission
control panel on the central tunnel fig. 43
are pressed, irrespective of the pressure
applied to the brake pedal.

Therefore, the transmission will remain in
the condition that it was in when the
engine was switched off.
With car stationary and key at MAR
(ignition-operated electrical services
activated), the screen displays the gear
engaged and the active operating mode
(automatic = AUTO or manual = no
display).
OPERATING MODE
The transmission can operate in two
operating modes (except when the “Race”
mode is selected):
❒ the first manual type (MANUAL), in
which the driver decides directly when to
change gear;
❒ the second completely automatic
(AUTO), in which the system decides
when to change gear.
When the “Race” mode is selected, the
only allowed operating mode is MANUAL.
Manual operation (MANUAL)
In this operating mode, the driver is
responsible for choosing the best gear
ratio to engage, depending on the car
operating conditions.Use the “+” steering wheel stalk to
engage a higher gear, or the “–” stalk to
engage a lower gear (see the following
paragraph, “Steering wheel stalks”).
If the request is accepted by the system,
the display shows the new gear engaged.
If the request is not accepted by the
system, the display shows the gear
engaged before the request and emits an
acoustic signal.
If the gear change request may adversely
affect the correct operation of the engine
and the transmission, the system will not
allow it.

STARTING AND DRIVING
72
The shifting up or down is only permitted
if the engine revs allow it.
STARTING THE ENGINE
To start the engine press the brake pedal:
the system engages neutral (N)
automatically.
After the starting procedure, 1st gear (1)
or reverse (R) can be engaged.
Irrespective of the mode selected
(AUTO/MANUAL), to engage 1st gear or
reverse (R), it is necessary to press the
brake pedal and press the 1 button on the
transmission control panel (or the “+”
steering wheel stalk) to engage 1st gear
or the R button to engage reverse.
When 1st gear is engaged, the system
sets itself to AUTO mode.
Neutral (N) can be engaged again by
pressing the N button with the brake
pedal pressed.
When the 1, N or R buttons are pressed
(or “+” steering wheel stalk is operated)
without pressing the brake pedal, no gear
change request is implemented by the
system.
IMPORTANT Reverse cannot be engaged
by pressing the “-” stalk on the steering
wheel.
Important notes
To start in presence of a gearbox fault
(see “Warning lights and messages”
paragraph in the “Knowing the instrument
panel” chapter), run the
“Delayed start-up” procedure:
turn the key to the AVV position for at
least 7 seconds with the brake depressed
and the engine will start.
The system will remain in “recovery”
condition.
If the engine does not start, contact a
dedicated Alfa Romeo Dealership.
When the driver’s door is opened, the
system activates the hydraulic
components so that they are prepared
for the subsequent engine starting.
MOVING THE CAR
The car can set off both in 1st gear and
reverse (R).
The gears can only be engaged by
pressing the brake pedal. If the brake
pedal is not depressed, the display will
show a dedicated message.It is not possible to set off in a higher gear
than 1st: if this is attempted, the display
shows a dedicated message.
When setting off on a medium-steep
incline, it is advisable to engage the
handbrake.
Engaging 1st gear
Proceed as follows:
❒ press the brake pedal;
❒ press the 1 button on the
transmission control panel;
❒ release the brake pedal and press the
accelerator pedal.
Engaging reverse (R)
Reverse (R) can only be engaged with car
stationary and brake pedal pressed.
Proceed as follows:
❒ press the brake pedal (car completely
stationary);
❒ press button R on the
gearbox panel;
❒ release the brake pedal and press the
accelerator pedal.
When reverse is engaged on some
versions, the system emits an acoustic
signal.
If the brake pedal is not depressed (and
the vehicle is stationary), the display will
show a dedicated message and the
system will automatically engage neutral
(N).

IMPORTANT With the car running, the
request is accepted and executed if the
car speed drops below 3 km/h within 3
seconds from the request: if the request
is not executed, the system will maintain
the gear engaged or, if the speed of the
car drops below 10 km/h, will put the
transmission in neutral (N) and the
manoeuvre will have to be repeated.
ENGAGING NEUTRAL (N)
With car stationary and ignition key at
MAR (irrespective of the condition of the
engine), neutral (N) can only be engaged
with the brake pedal pressed.
If the car is in motion, neutral (N) can
always be engaged, irrespective of the
pressure applied to the brake and
accelerator pedals.
The display will show the letter N
together with the active operating mode.To engage a speed from the neutral (N)
position, press button 1 on the gearbox
panel (it is not necessary to press the
brake pedal):
the gearbox will immediately choose the
correct gear according to the vehicle’s
speed.
With car stationary and ignition key at
MAR (irrespective of the condition of the
engine), 1
stgear can only be engaged with
the brake pedal pressed.
LAUNCH CONTROL
The “Launch Control” strategy permits
high-performance starting.
This strategy can be activated with
vehicle at a standstill, “Race” mode
selected and 1st gear engaged.
The sequence of operations to perform is
as follows:
❒ press the brake pedal and hold it
down;
❒ press the accelerator pedal and hold it
down;
❒ press the “–” paddle behind the
steering wheel;The car will start off at maximum
acceleration when the brake pedal is
released.
Keeping the accelerator pressed, the
system will automatically upshift once
the best engine speed has been achieved
for shifting gears.
78)
To abandon the strategy, simply interrupt
the above sequence of operations or
release the accelerator pedal.
DISPLAYED INFORMATION
When the key is turned to MAR-ON, after
about 1 second, the display shows the
transmission in neutral indication (N).
When driving, the display shows the gear
engaged and the active mode (AUTO or
MANUAL). The indications on the display
have the following meanings:
N = neutral;
1 = first gear;
2 = second gear
3 = third gear;
4 = fourth gear;
5 = fifth gear;
6 = sixth gear;
R = reverse.
