General Installation Notes:
Please read instructions completely before beginning this procedure. If you
have any questions please call.
Do not attempt to install this product while the engine is running. Disconnect
negative battery cable before beginning installation.
Make sure the engine, transmission, body and frame are properly grounded.
The following instructions are for adjusting the Neutral Safety Switch in the
Lokar Automatic Transmission Shifter using the included Aluminum Adjuster
Plug (Fig. 1).
Please note that final adjustment of the Neutral Safety Switch must be done
after the shifter has been installed into the vehicle. If your Neutral Safety
Switch is wired properly and the vehicle is starting in any gear other than
Park or Neutral while using the Lokar Shifter, you must adjust the Neutral
Safety Switch.
The Lokar Neutral Safety Switch passes current (is turned on) when the ball
is pushed in. It does not pass current (is turned off) when the ball is out at
its at-rest position.
WARNING: Before making any adjustments or taking the shifter out of Park,
be sure that the vehicle’s tires are scotched and the parking brake is set to
prevent movement of the vehicle.
The release button should be flush with the knob in Park and Neutral.
In the Reverse position, you cannot pull the lever into Neutral without
depressing the release button.
Step 1: Make sure that the left banana bracket to gear plate bolts are
tight. Fig. 2
Step 2: For the Neutral Safety Switch to function properly, the shifter
linkage must be adjusted correctly. You MUST verify that the
shifter linkage is adjusted correctly before attempting to adjust
the Neutral Safety Switch.
To verify this, put the shifter into Park. Remove the 1/4"-28 x 1"
button head bolt with nylock nut that attaches the rod end to the
lever at either end of the threaded rod. Make sure the hole in the
rod end exactly aligns with the hole in the lever. The bolt should
pass freely through both holes at the same time without binding.
Do not force the holes to line up.

Step 2: (Continued) If you encounter a bind, loosen the jam nut on the
threaded rod and screw the rod end in or out to eliminate the
bind. Do this without moving any shifter/transmission levers or
arms. Use this adjustment routine until the bolt will pass freely
in and out of both the rod end and the lever. Reinstall the
1/4"-28 nylock nut and the flat washer onto the bolt and tighten.
Step 3: Once you have the shifter linkage adjusted properly, remove the
Neutral Safety Switch and washer using a 7/8" wrench or socket.

Step 4: Loosen, but do not remove, the two 5/16"-24 x 3/8" button head
bolts that attach the right banana bracket to the switch plate
(the bolts are in curved, slotted holes). Fig. 3
Step 5: Put the shifter into the Reverse position.
Step 6: Reposition the switch plate so that the hole in the switch plate
lines up with the center groove in the shifter body. Fig. 4 Screw
the provided aluminum adjuster plug into the Neutral Safety
Switch opening. Wiggling the shifter lever slightly while you are
screwing the adjuster plug in will help get the shifter body cen-
tered on the plug. Fig. 5
Step 7: Retighten the two 5/16"-24 x 3/8" button head bolts that attach
the right banana bracket to the switch plate.
Step 8: Remove the aluminum adjuster plug, and reinstall the Neutral
Safety Switch and washer. Test for continuity by connecting an
ohmmeter lead to each stud on the Neutral Safety Switch. When
adjusted correctly, you will only have continuity between the two
switch studs when the shifter is in Park or Neutral. Continuity
in any other gear requires readjustment of the Neutral Safety
Switch.
Reconnect negative battery cable and check operation.
If your car should ever start in any gear other than Park or
Neutral, please readjust the Neutral Safety Switch accordingly.
Tighten all brackets and bolts correctly and securely and there
should be no movement or maladjustment. If you have any
questions after following this procedure, please call Lokar
Technical Support.
