OPERATION
16S 2230 Manual transmission and shifting
High range 5-6-7-8
Manual gear
Half gear
(boost)
Low range 1-2-3-4
There are 16 forward and 2 reverse (in high and low
ranges) gears. All gears other than the reverse gears
have synchronizers. Shifting from low to high range and
selection of half (boost) gears is made via the latches on
the gear knob. As shown in the diagram below, the latch
in the front side of the gear knob allows selection of the
low range (1-2-3-4) and the high range (5-6-7-8). When
the latch is down, the transmission is in the low range;
and when the latch is up, the transmission is in the high
range. The latch on the side of the gear knob allows
selection of half (boost) gears. When the latch is down,
the transmission is in boost gear; and when the latch is
up, the transmission is in normal gear.
Note:
To shift from low range to high range during
acceleration in transmissions with 1H gear system:
1. Press the latch upwards in the 4th gear.
2. Depress the clutch pedal.
3. Select neutral.
4. Shift the lever from neutral to ½ range and then 1/5 gear.
Transmission will shift to 5th gear when it is in high range.
5. Slowly release the clutch pedal.
6. Leave the latch in high range.
16 S 2230 transmissions have a shift prevention
mechanism to protect the transmission against
incorrect shifts when the vehicle has reached a certain
speed. These mechanisms prevent shifts to ½ range in
certain speeds for low and high ranges, and shifts from
high range to low range.
Below are the cases reflecting the above mentioned
circumstances and where the protection mechanisms
are activated for errors likely to be experienced when
driving:
1- Driver wants to shift from 4th to 5th, but forgets
the switch the latch to high range (upwards) when
the vehicle is accelerating: The gear knob cannot be
moved to 1/2 position, changing to an incorrect gear is
prevented by the system.
2- Driver wants to shift from 6th to 5th, but switches
the latch to low range inadvertently when the vehicle
is decelerating: As the transmission will try to shift to
1st in this condition, the shift prevention mechanism is
activated and prevents the shift operation, and moves
the shift lever to the ¾ range, and changing to an
incorrect gear is prevented by the system.
3- Trying to shift from 8th to 5th when the vehicle is
moving with a certain speed: Selector lever 1
The gear knob cannot be moved to 1/2 position,
changing to an incorrect gear is prevented by the
system.
4- Trying to shift from low range to high range when the
vehicle is moving with a certain speed: System denies
the shift to the low range. Driver is not allowed to shift
to low range.
Prevention mechanisms of the 16 S 2230 transmission
specified above are intended to protect the gear and
synchronizer mechanisms in the transmission, and
these are not error modes.
CAUTION
Service life of the clutch is proportional with its correct
usage.
Incorrect usage of the clutch reduces its service life
and clutch is damaged because of overheating in a
short period of time.
Do not hold the vehicle on slopes with semi-applied
clutch.
