STEP 13. If you have not already done
so, remove the nut and the lockwasher
holding the downshift linkage onto the
downshift lever shaft. The downshift lever
is the outer lever on C-4, C-5 and C-6
transmissions. Pull the lever off the shaft
and allow the linkage to hang free. Re-
move and discard the stock shift linkage
rods. Some C-6, late C-4 and all C-5
transmissions have a neutral safety/
backup light switch on the transmission
shift lever. If your transmission is so
equipped, remove the two bolts holding
the switch in place and slide it off the shift
shaft. Disconnect the switch at the factory
plug and discard it.
STEP 14. Install the B&M selector lever
(See Figure 4 or 5). Note: The B&M lever
must point downward for proper opera-
tion. If the stock shift lever on your trans-
mission points down, you will have to
remove the lower part of the stock arm by
cutting it off to clear the B&M lever (See
Figure 4). Install the B&M selector lever
onto the shift shaft of the transmission.
Align the selector lever so when it points
straight down it travels equal arcs in both
directions from the center, then tighten
the ¼”-20 x 1 ½” pinch bolt and the nut.
The lever should travel smoothly from
front to back with a positive click in each
gear position. Make sure the o-ring is in
position on the downshift shaft and install
the downshift lever in position on the
shaft. Install the lockwasher and the nut
and tighten securely. The downshift lever
must operate smoothly. Reconnect the
downshift linkage.
STEP 15. Cable bracket installation:
C-4, C-5: Remove the two lower bolts
from the rear servo cover. Install the cable
bracket in position (See Figure 4). Install
the two servo cover bolts as removed and
tighten to 12-13 lb. ft. Do not overtighten
as this can distort the servo cover.
C-6: Remove the two transmission oil
pan bolts from the left rear corner of the oil
pan. Install the cable bracket into position
with the two spacers between the pan and
the bracket (See Figure 5). (If your trans-
mission is equipped with a cast aluminum
oil pan, these spacers can be omitted).
Install 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.
STEP 16. Route the shifter cable accord-
ing to Figure 2. 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
the threaded end of the shifter cable.
Slide the end of the cable into the cable
bracket. Install the large nut and the
lockwasher loosely over end of cable.
Install the two rubber boots onto the end
of cable. Install the swivel on the threaded
end of the cable and position it in the
center of the threaded portion.
STEP 17. Be sure that the Park limiter
blocker pin and the three speed limiter
blocker pin are both installed as shown in
Figure 1. The Park limiter will prevent the
shifter from additional travel beyond the
Ford Park position. (GM transmissions
have greater travel between Neutral and
Park than Ford transmissions do). The
three speed limiter blocker pin is required
because all Ford three and four speed
automatic transmissions have only three
forward gear positions, even the four
speed AOD.
Move the transmission selector lever
by hand to full rear position (Low). Shift
the shifter mechanism to the Low gear
position (ratcheted back until it is stopped
by the three speed limiter blocker pin).
Adjust the large nuts on the cable so that
the swivel will slide into the hole on the
selector lever. Tighten the large nuts
completely. Be sure that the swivel will
slide freely in and out of the hole in the
selector lever.
With the swivel in the selector lever,
shift the shifter to the Park position, as far
forward as the shifter will go without forc-
ing it. (The Park limiter blocker pin will
prevent the shifter from moving any fur-
ther). The shift lever on the transmission
should be all the way forward. Check to
see that the swivel will slide freely in and
out of the hole in the lever in this position.
If it does not slip in freely, adjust the swivel
slightly until it will slip into the hole in the
lever in both Low and Park positions.
Operate the shifter through all the gear
positions. Check to make sure the swivel
will slide in and out of the selector lever
hole in each gear position. Install the
cotter key supplied with the shifter into the
swivel and spread the key ends. Rein-
stall the downshift linkage, tightening the
nut securely.
If you have a problem, DO NOT
FORCE THE SHIFTER, this will damage
the cable, the shifter or the transmission.
Simply start at the beginning and carefully
check all your steps.
STEP 18. On Ford vehicles, the neutral
safety/backup light switch is located on
the transmission (or on the steering col-
umn on some early vehicles). If the ve-
hicle has an AOD transmission the neu-
tral safety/backup light switches on the
B&M QuickSilver Shifter will NOT be
used. The neutral safety/backup light
switch on C-3 or AOD transmissions will
continue to function normally.
On the C-4 and C-5 transmissions it
is necessary to completely remove the
stock neutral safety/backup light switch in
order to install the B&M transmission shift
lever. On C-4, C-5 and C-6 transmissions,
it will be necessary to hook up the neutral
safety/backup light switches on the B&M
QuickSilver Shifter. Locate and identify
the neutral safety (the engine will not
crank unless these wires are connected
together), and reverse light wires. Dis-
connect the battery ground cable before
beginning to wire the neutral safety and
