Diagnosis

Diagnosis (Cont'd)

The Transmission Range Switch (TRS) is located on
the right hand side of the transmission, as shown in
Figure 23. The TRS is a mechanical multi-position
switch with 6 sliding contacts, four selector position
switches, one reverse switch and one switch for
positions P/N, for starting control.
The TRS is shown in Figure 22 and if removed or
replaced, a position to the selector (manual) shaft
must be set using special tool from Volkswagen.

The only ignition voltage sent to the switch goes in at
terminal 10 and goes through only the reverse switch,
as shown in Figure 24. Voltage exits through terminal
8 and is sent to the reverse lamps and the TCM.
Diagnosis here is easily done using a volt meter.

The remainder of the switches provide a ground
signal for the starter relay through the P/N switch and
ground signal to the TCM through the position
switches, as shown in Figure 24. These switches
must be checked with the DVOM set to Ohms. Notice
in Figure 24 that terminals 3 and 4 provide the ground
into the switches. Use the Ohm meter across
terminals 4 and 2 to check for the Park and Neutral
positions, as shown in the chart provided in Figure 24.
With the Ohm meter on terminal 3, you should have
continuity across the terminals shown in the chart in
Figure 24, related to the position of the gear selector
lever.

When the "Park" position is selected, there is no
powerflow through the transmission. The parking
pawl is engaged which locks the output shaft to the
case. The engine can be started and the ignition key
can be removed.

P

When the "Neutral" position is selected, there is no
powerflow through the transmission. The output
shaft is not held and is free to rotate and the engine can
be started. This position can also be selected while
the vehicle is moving, to restart the engine if that
becomes necessary.

N

When the "Reverse" position is selected, the
vehicle can be operated in a rearward direction at a
reduced gear ratio.

R

When the "Sport" position is selected, the lock
button must be pressed to shift into "S", the TCM will
select gears automatically using a performance
oriented shifting program.
When the shift lever in the "S" position and moved
into the right hand selector gate, it enables the driver
to select the range of gears by tapping the selector
lever towards the "-" or "+" to cause the transaxle to
downshift or upshift.

S

S - Cont'd

The "Drive" position is the normal position for
most forward gear operations. The Drive position
provides automatic upshifts and downshifts, apply
and release of the converter clutch, and maximum fuel
economy during normal operation. Drive range
allows the transmission to operate in each of the six
forward gear ratios. Downshifts are available for safe
passing, by depressing the accelerator.
The "Tiptronic" in the Touareg is available in the
selector lever as well as the steering wheel, by moving
the selector lever to the right out of the "D" position.

When towing, the ATF pump is not operated, and
therefore rotating components are not lubricated. To
avoid severe damage to the transaxle, the following
conditions must be met:
- The selector lever must be in the “N” Neutral
position.
- Towing speed must not exceed 31 mph
(50km/h).
- Vehicle must not be towed further than 31 miles
(50 km).

- Automatic upshifts when the maximum RPM is
reached.
- Automatic downshifts when the RPM falls
below the programed minimum RPM.
- Kickdown shifting available.
- Acceleration from standing start in second gear
by selecting 2nd before accelerating.
- Upshift or downshift prevention.

Steering wheel paddles are available as options,as
shown in Figure 25, and they also will vary in
appearance with the different vehicle applications.
However, operation and function remains the same
with the TF-60SN. These operational paddles are
found in the steering wheel on the left and right hand
side, as shown in Figure 25.
Upshifts and downshifts occur by tapping the
appropriate paddle. The shift signals are an input to
the TCM, which in turn carries out the request.
If the Tiptronic paddles in the steering wheel are
operated while in automatic mode, the TCM enters
"Tiptronic Mode". If the paddles are not operated, the
TCM returns to the automatic mode after a
preprogramed amount of time.
In case of a signal failure, no Tiptronic functions are
possible using the steering wheel paddles.

These vehicles are also equipped with an LED
display on the instrument panel that will display the
gear selected with the selector lever, as shown in
Figure 26.
When the vehicle is first started, the display will be
"P", as shown in Figure 26. If reverse is selected the
"R" will be displayed.
When Drive is selected for the automatic forward
mode the "D" will be displayed momentarily and will
then go to "1", as you are still in first gear. As you are
driving, the gear that the transaxle is in will be
displayed on the instrument panel.
When in the Tiptronic Mode, the gear selected by
pressing the paddles will be displayed in the
instrument panel. Keep in mind that 2nd gear starts
can be achieved using this feature. 3rd gear standing
starts are not allowed.

Figure 26

In mechanical emergency running mode, 3rd gear is
always engaged. If the transmission is already in 4th,
5th or 6th gear, the current gear is maintained until the
selector lever is placed into the neutral position and
the engine is stopped.
When starting off, 3rd gear is always engaged
whether the selector lever is in the D or S position.
Reverse is available.
System pressure is controlled to the maximum value;
the shifting elements are pressurized to maximum
shifting pressure. This results in a hard shift when
engaging the driving mode. The torque converter
lock-up clutch remains off.
