The gearbox is a new development and is
designed for transmitting engine torques of
up to 200 Nm.
Gearbox designation
02TA for petrol engines of 55 and 74 kW

5-speed manual gearbox
–
Double synchromesh for 1st and 2nd gear
(improved shift quality)
–
Hydraulic clutch control, design based on
gearbox 002
–
Manual gearbox and final drive form a
single constructional unit; new materials
used for achieving weight reductions
Internal shift mechanism (shift forks) is
designed as a shift arm mechanism; shift
shaft enters the gearbox from the top
–
Transmission oil filled for entire service
life; no oil change necessary
Needle bearings for sliding gears in order
to reduce the internal friction

New!
The speedometer drive
The speedometer is driven without any
mechanical intermediate stages.
No speedometer gear, no speedometer shaft.
The information regarding the road speed of
the vehicle is tapped directly at the differential
housing by the speedometer sender G22.
The differential housing is provided with
reference marks for this purpose.
Speedometer
sender G22
The speedometer sensor takes the place of the
speedometer shaft at the gearbox.

SP32_23
The information is passed electrically in the
form of pulses from the speedometer sender
to the control unit in the dash panel insert. It is
processed there for indicating the vehicle
speed and the distance.
Advantage:
Optimal accuracy of indications and smooth
needle readings.
You can find further information on the
gearbox in SSP 37.

Gearboxes
Gearbox 002
Gearbox designation
002H for 1.0-ltr./37 kW engines
002G for 1.4-ltr./50 kW engines
The difference is in the inner transmission
ratio.
The gearbox is a further development of the
gearbox described in SSP 27.
Highlights of the technical modifications
The shift movements are transmitted into
the gearbox from above.
–
At the top on the gearbox there is a shift
cover which houses the shift shaft for the
internal shift mechanism and the relay of
the shift movement.
–
The gears are shifted by means of shift
arms. The shift pattern is matched to the
standard pattern.
–
The external shift mechanism has been
simplified. It has a similar operating
principle to the cable shift mechanism in
the OCTAVIA.
–
A locking pin is provided at the shift cover
with which it is possible to fix the shift
shaft in a predefined position.
This greatly simplifies the adjustment of
the cable shift mechanism.

Shift mechanism
The shift movement is transmitted from the
shift lever into the gearbox by means of two
cables in all the gearbox versions.
The principle used for relaying the shift
movements from the hand shift lever to the
gearbox shift lever is the same as that
employed on the OCTAVIA.

Engine/gearbox mounting
The engine/gearbox mounting is similar to the
pendulum mounting (3-point mounting)
familiar from the OCTAVIA.
Engine mount with
mounting bracket
Gearbox mount with

The engine and gearbox mounts are
positioned around the pivot axis of the power
plant.
The pendulum support absorbs tensile and
compressive forces.
The bearing mounting brackets are matched
to the particular engine type.

Both are connected to the fuel tank by flexible
plastic lines.
The fuel pressure regulator is an integral part
of the fuel filter. It is no longer positioned at
the fuel rail of the engine.

In contrast to the predecessor version, the
activated charcoal filter is not located in the
left rear wheelhouse, but behind the
wheelhouse liner behind the right rear wing.
Venting when refuelling
Venting when driving
When the cap is removed, the vent valve
automatically shuts off the vent line to the
operating vent tank.
The unleaded petrol flap shuts off the filler
neck by means of the spring tension. The cap
on the filler neck pushes open the vent valve.
Fuel vapours from the fuel tank thus do not
escape to atmosphere during refuelling.
Fuel vapours which form as a result of the fuel
warming up, flow into the operating vent tank.
These vapours pass through the opened vent
valve and the filler neck, which is sealed off to
atmosphere, through the gravity valve to
activated charcoal filter where they are
bonded.
The unleaded petrol flap is opened by the
refuelling nozzle.
The air from the fuel tank is passed to the
refuelling vent tank during refuelling and from
there to the fuel filler neck.

Fuel System
Fuel filter with pressure regulating
valve
New!
Fuel filter and pressure regulating valve are a
combined component.
This is positioned directly at the fuel tank and
is divided into a spring chamber and a filter
chamber.
The fuel pump pumps fuel into the filter
chamber, the pressure regulating valve
maintains the system pressure of 3 bar
(0.3 MPa), which is effective in the fuel rail at
the injectors.
SP32_31
The fuel is metered to the filter by means of an
orifice plate in order to maintain the pressure.
Regulating valve
If the pressure rises above 3 bar (0.3 MPa), the
regulating valve to the spring chamber opens.
Excessive pumped fuel flows back along the
shortest path unfiltered through the regulating
valve into the fuel tank without having to take
the long way round through the engine
compartment.
Spring chamber

SP32_32
Advantages:
This makes it possible to eliminate the returnflow line from the engine to the fuel tank. The
fuel which flows back is warmed up less, the
temperature in the fuel tank remains lower
and the quantity of evaporating fuel is
reduced.
The fuel flowing back is not filtered. The
service life of the filter is extended.
26
Note:
The fuel injection system in engine has
been modified accordingly.
The engine now has a fuel rail through
which the fuel does not flow.
