B&M 80683 QUICKSILVER SHIFTER - Manual (Page 2)

hole of the mechanism must be at least
1¾” from the front of the seat when the
seat is in the full forward position). Make
sure the knob clears the dash with the
shifter in the Park position. Mark the po-
sition of four mounting holes on the floor.
STEP 3. Drill the four 9/32" mounting
holes where marked. Temporarily mount
the shifter in place using the washers as
required to get it level. Mark the location
for the shifter cable hole, 3" ahead of the
front shifter mounting hole. Drill or cut a
1½” diameter cable hole in the floorboard.
NOTE: Some floorboards are extremely
thin and will not adequately support the
shifter mechanism when bolted to the
floor. For those vehicles we recommend
that you fabricate a stiffener plate for
additional strength.
STEP 4. Install (but do not secure) the
carpet back to it’s original position. Cut holes in the carpet for the mounting holes
and a 1½” slit for the cable. DO NOT use a
drill bit to make holes in the carpet.
STEP 5. Install the cable on the shifter as
shown in Figure 1. The cable attachment
tab must be bolted to the outside surface
of the shifter base using the supplied ¼” X
½” hex bolt, lock washer and nut. Put the
end of the indicator link on the cable pin
outside of the shifter cable. Install the e-
clip to secure the cable.
STEP 6. Install the backup light switch and
the neutral safety switch in place on the
shifter mechanism. Install them using the
two supplied #4-40 screws, nuts and lock
washers, as shown in Figure 1. If neces-
sary, bend the fingers slightly so that they
engage the slots. Beware, overtightening
the switch attachment screws will crack
the switch housings. Adjust the switches
so that the neutral safety switch (the lower
switch) operates in Neutral and Park
only and so that the backup light switch
(the upper switch) operates in Reverse
only by loosening the screws and slid-
ing the switch as required. Then re-
tighten the screws.
STEP 7. Install the shifter mechanism
into the vehicle. Slide the shifter cable
through the carpet and the hole in the
floorboard. Bolt the shifter down using
four ¼” hex bolts and nuts. If required
use ¼” washers as shims between the
shifter mechanism and the floor to level
the shifter. ROUTE THE CABLE AS
SHOWN IN FIGURE 2, AVOID SHARP
BENDS WHICH WILL KINK AND DAM-
AGE THE CABLE. Use cable clamps or
tie wraps to secure the cable housing to
the chassis to avoid contact with hot
engine or exhaust system. Seal the cable
hole shut to avoid the entry of exhaust
fumes or water. For General Motors
vehicles go to Step 8, for Ford vehicles
go to Step 13, for Chrysler vehicles go
to Step 19.
GENERAL MOTORS
STEP 8. If you have not already done so,
remove the stock selector lever nut and
the selector lever. Discard the stock
lever and the stock shifter linkage. In-
stall the B&M selector lever in position
using the stock selector lever nut (See
Figure 3). Torque the nut to 23 lb. ft. The
lever should move smoothly from front
to rear with a positive click in each gear
position.
STEP 9. Remove the two transmission
oil pan bolts from the middle of the left
side of the oil pan. Install the cable
bracket in position (See Figure 3). The
bracket must be installed with two spac-
ers between the pan and the bracket. (If
your transmission is equipped with a
cast aluminum oil pan, these spacers
should be omitted however the cable
bracket may have to be modified). In-
stall the two supplied 5/16-18 x 1.00"
bolts and tighten to 12-13 lb. ft. Do not
overtighten as this can damage the pan
gasket.
Note: In some cases possible modifi-
cation to the GM cable bracket might
be required for the 4L80E and 4L85E
transmissions without the PRNDL
switch. Verify that selector lever does
not grind on cable bracket before
moving on to step 10.
STEP 10.Route the shifter cable ac-
cording to Figure 3. Avoid kinks and
sharp bends and route the cable away
from hot engine or exhaust parts.
Remove the two rubber boots, one
large nut, and a large lockwasher from
