to be removed from floor tunnel. Check area under floor
tunnel for obstructions before drilling. Drill a series of
starter holes through floor tunnel and cut opening to size
using metal shears. Make four (4) punch marks for
mounting hole centers through template. Drill four (4)
9/32” holes for mounting shifter assembly. Deburr holes
using a coarse file.
4. Fasten lever (extender for shifter) to the shifter
mechanism using two (2) 1/4-20 X 1” hex head bolts,
lockwashers and hex nuts as shown in the drawings.
Pierce end of lever through weather seal (plastic sheet).
Refer to Typical Shifter Installation.
5. Place lever of shifter through hole in floor tunnel and
move stick forward and backward to be sure that its travel
is not obstructed. Reshape contour of floor tunnel as
necessary to provide clearance for shifter and linkage to
have free travel. Lever of shifter may be bent or cut off as
necessary for clearance purposes.
6. The shifter is assembled at the factory to operate in a
pattern that has PARK position where the stick is all the
way forward. If your shift pattern has the PARK position
where the stick would be located in the extreme rear
position, you will have to drive the dowel pin in the lower
end of the stick, through to the other side of the stick. This
will allow travel of the stick to be limited by the track cut
into the other side plate. PARK position will be at the
opposite end (rear) of this track.
7. Fasten shifter to floor tunnel using four (4) 1/4-20 X 1”
hex head bolts, flatwashers, lockwashers, and nuts. Use
spacer washers (not supplied) if necessary to raise shifter
off floor tunnel.
TRANSMISSION ARM/ADAPTER & LINKAGE INSTALLATION
1. Refer to the illustration that pertains to your vehicle
application. Use the transmission arm/adapter required
and install it to the transmission arm or transmission
selector shaft as indicated per illustrations.
IMPORTANT: Shifter linkage must not interfere with the
throttle linkage. To retain the function of the Neutral Safety
Switch and Back-Up Light Switch, you must retain operation
of stock linkage from transmission, back to the steering
column. Retaining this linkage may require some fabrication
depending upon the vehicle.
If stock linkage is not retained, Neutral Safety Switch and
Back-Up Light Switch must be relocated or else vehicle
will start in other gear selections (other than PARK or
NEUTRAL) and Back-Up Lights will not operate. It is
recommended to retain the stock linkage if possible.
2. Assemble threaded rod button onto the linkage rod.
Connect linkage rod as indicated in the illustration that
pertains to your vehicle. Some installations have the
threaded end located at the front, others have it located
at the rear.
The length of the shifter stick throw is determined by
which holes are used in the shifter lever. The holes that
are closest to the pivot points are the ones that provide
the shortest throw. Linkage rod may need to be bent to
clear obstructions. Place rod in a vise if necessary and
bend carefully, avoid sharp bends. Fasten linkage
securely using two (2) spring clips supplied.
3. Test shifter (DO NOT START ENGINE), stick should
move through shift pattern easily and entirely without
binding. If necessary, detach rod adjusting button from
transmission arm or lever, and turn it in the direction that
will allow full travel.
IMPORTANT: Lubricate all moving shifter components
thoroughly using moly base grease on a regular basis to
ensure smooth shifting operation.
4. Remove knob, slide boot and trim plate down to floor.
Use trim plate as template and drill holes through floor
tunnel. Fasten boot using four (4) #10 X 1” pan head
screws supplied.
5. A pressure sensitive gear indicator label is supplied with
various shift patterns. Place next to the shifter stick, if
desired.
NEUTRAL SAFETY SWITCH AND BACK-UP LIGHT SWITCH
TEST OPERATION
Disconnect the battery wire from distributor so engine will
crank but not start. Place shifter in PARK position and apply
pressure to brake pedal. Test starter motor in every gear
position of the shift pattern. The starter motor must operate
in PARK and NEUTRAL gear positions ONLY. If starter
operates in any other gear position, re-check wiring to be
sure connections and adjustment of switches are correct.
Also, test operation of back-up lights – lights should operate
in REVERSE only. Connect battery wire to distributor so
engine will start.
