7/16" nut
C-4 cable bracket
Cable swivel
Cotter pin
Ford lever
Ford C-4 and C-5
1/4 x 1-1/2" bolt,
lockwasher and nut
bolts supplied and tighten to 12-13 lb.ft.
Do not overtighten as this can damage
the pan gasket.
STEP 18.Route the shifter cable accord-
ing to Figure 4. 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 the end of the
cable. Install the two rubber boots onto
the end of the cable. Install the swivel on
the threaded end of the cable and posi-
tion it in the center of the threaded portion.
STEP 19.Move the transmission selec-
tor lever by hand to full rear position
(Low). Place the shifter lever to the Low
gear position (ratcheted all the way back).
Adjust the large nuts on the cable so that
the swivel will slide into the hole on the
selector lever. Tighten the large nuts com-
pletely. 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,
move the shifter to Park position, as far
forward as the shifter will go without forc-
ing it. (The shifter has further travel that
is used to reach the GM Park position but
is not used on Ford transmissions. Try-
ing to force the cable will damage the
cable.) The shift lever on the transmis-
sion should be all the way forward. Check
Figure 6
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 16. Install the B&M selector lever
(See Figure 6 or 7). 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 6). 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 1/4"-20 x 1 1/2" pinch bolt and 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 posi-
tion 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 down-
shift linkage.
STEP 17. Cable bracket installation:
AOD: Instructions for the AOD are in-
cluded with the optional installation kit
#40496.
C-4, C-5: Remove the two lower bolts
from the rear servo cover. Install the cable
bracket in position (See Figure 6). 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 in posi-
tion (See Figure 7) with two spacers be-
tween the pan and the bracket. (If your
transmission is equipped with a cast
aluminum oil pan, these spacers can be
omitted.) Install the two 5/16-18 x 1.00"
