Step 1: If your vehicle already has a shifter of any type installed, disconnect all shifter linkage and remove
the shifter and its related hardware (neutral safety switch, back-up light switch, etc.).
Step 2: In the Lokar shifter kit you are supplied with two aluminum side mounting buttons that are
approximately 5/8" in diameter. Your transmission has two round, hollow bosses cast into the
case, one on the left side and one on the right side. Clean any paint or debris out of these
bosses, and install the side mounting buttons into the bosses with the flat side in toward the
transmission case.

Step 3: The main plate has two 5/16"-24 tension set screw holes. One set screw hole is in the center
of the main plate, and the other set screw hole is at one end of the main plate. The main plate
will be installed so that the end of the main plate that has a set screw hole will go to the front
(towards the engine), and the end that does not have a set screw hole will go to the rear.
The left side bracket and right side bracket bolt directly to the main plate.
NOTE: The right
side bracket will be offset rearward on the main plate by one slot, compared to the left side
bracket. Attach the side brackets to the underside of the main plate as shown in Fig. 3, using
three 5/16"-24 x 1/2" button head bolts and lock washers on each side.
DO NOT TIGHTEN
AT THIS TIME.
Step 4: (2 Wheel Drive Transmissions) Attach the rear mounting bracket to the underside of the main
plate with the bracket ears pointing to the front of the transmission (toward the engine) as shown
in
Fig. 3, using two 5/16"-24 x 1/2" button head bolts and lock washers. DO NOT TIGHTEN AT
THIS TIME.
(4 Wheel Drive Transmissions) You will not be using the rear mounting bracket.
Step 5: (2 Wheel Drive Transmissions) Remove the top two tail housing bolts from the transmission.
Install the mounting bracket assembly onto the transmission by first installing two
3/8"-16 x 1-1/4" button head bolts with lock washers through the rear mounting bracket and
into the transmission at the tail housing.

(4 Wheel Drive Transmissions) Start the 5/16"-24 x 5/8" tension set screws into the tension set
screw holes at the front and in the center of the shifter main plate. Set the mounting bracket
assembly into place on top of the transmission.

Step 6: (All) Install the 3/8"-24 x 1" tension set screws through the side brackets into each side mounting
button, but do not tighten.
Step 7: (All) Tighten all of the bolts on the left, right, and rear mounting brackets, leaving the tension
set screws for last. Tighten the tension set screws on the side brackets until the side brackets
move outwards about 1/8”. On 4 wheel drive transmissions, tighten the set screws in the main
plate last, threading them in until they contact the top of the transmission case (2 wheel drive
transmissions do not require set screws in the main plate). Finally, install a 3/8"-24 jam nut
onto the tension set screws on the side brackets and tighten.
(4 Wheel Drive Transmissions) Install and tighten the 5/16"-24 jam nuts on the set screws in the
main plate.
Step 8: You are now ready to position your shifter assembly onto the main plate. There are several
mounting position options from front to rear on the transmission.
If your vehicle already has an opening in the tunnel for the shifter and the engine is installed
in the vehicle, measure from the rear face of the engine block to the center of your existing
shifter opening. If your engine is not yet installed in the vehicle, measure from the engine
mounts to the center of the existing shifter opening instead.
If the vehicle does not have an existing shifter opening in the transmission tunnel, decide
where you want the shifter to be positioned so that it will be comfortable and will not interfere
with the dash or a bench seat (if applicable). Mark that spot on the tunnel, and measure as
described above.
