Put the pin remover back onto the gearstick, and drop the roll pin into the threaded hole, followed by the
shorter of the two M5 slot screws. Make sure the end of the roll pin is lined up with the end of the long
M5 slot screw, then begin screwing it into the gearstick (fig. 15). If aligned correctly, the roll pin will
push the longer M5 slot screw out of the gearstick as it is pushed in. Continue until the pin is pushed
about 1mm BEYOND centre. Now unwind the short M5 slot screw, spin the roll pin remover 180
degrees and push the pin back the other way until it is centred (fig. 16). This will ensure the end of the
cable is held in the middle of the gearstick, instead of rubbing against the side (look down the hole in the
top of the gearstick, you will be able to see the position of the cable).
17. Check the operation of the reverse lever, then fasten the reverse cable with the supplied zip tie.

At this point you will need to decide how short you want the
shift throw to be. This is determined by the height of the
clamp on the gearstick relative to the pivot ball – the higher
the clamp, the shorter the throw (Note: the shorter you make
the throw, the more force will be required to shift, this is
normal). The 3 holes in the blue plates simply ensure that
the gearbox linkage remains at the correct angle (so it
doesn’t foul on the transmission tunnel) regardless of the
clamp position. We suggest beginning with the middle hole.
Make sure the factory steel sleeve is inserted into the white
bushings of the gearstick clamp, then line up the sleeve with
the middle hole. Hold one of the M8 washers between the sleeve and the side plate, then slide the
factory bolt through the side plate, the washer, and into the sleeve. Note that you may have to adjust the
height of the clamp on the gearstick to get the bolt through the holes. Position the second washer on the
other side (fig 13), and push the bolt fully through. Partially thread the nut onto the end of the bolt,
tighten the screw in the gearstick clamp and test the shift feel. If the throw is too short or long, make an
adjustment to the height of the clamp, and if necessary, select a different hole on the side plates so that
the gearbox linkage does not rub or foul in any gear.
Note that as you slide the clamp up and down, the neutral position of the gearstick will move slightly.
By using the combination of the clamp height and hole position, you can tailor the shift feel to your
liking. Once you are satisfied tighten the clamp screw and linkage bolt, then perform a final check to
ensure that you can select all gears (including reverse) smoothly, and without any binding. Replace the
plastic shrouds in the reverse order of removal.
