Manual Transmission - Porsche 928 1982 Owner's Manual

Gearshifting

(Manual Transmission)

The Porsche transmission with servo-lock
synchronisation permits rapid and precise
shifting of gears. When changing gears
make sure that the clutch pedal is fully de-
pressed to the floor, and that the gearshift
lever is completely engaged. The engine
speeds for the individual gears are listed in
the chart on this page.
44
The clutch pedal must be depressed several
seconds before shifting into reverse; only
then move the gearshift lever to the left,
overcoming the spring resistance, and to the
front.
Both back-up lights come on when the trans-
mission is put into reverse (with ignition on).
Reverse should only be selected after the
vehicle has come to a complete stillstand.
The gear positions are shown in the diagram
above.
If you wish to shift from 1st gear into Reverse,
the gearshift lever must first be brought into
the Neutral position between 4th and 5th gear
and then shifted into Reverse. This is neces-
sary because of the reverse gear lock-out
mechanism.
