as this can damage pan gasket.
STEP 23. 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 large nut and lockwasher loosely
over end of cable. Install two rubber boots
onto end of cable. Install the swivel on the
threaded end of the cable and position it in
the center of the threaded portion.
STEP 24. Move the transmission selector
lever by hand to full forward position (LOW).
Place the shifter lever to the low gear posi-
tion (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 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,
move the shifter to PARK position, as far
forward as the shifter will go without forcing
it. (The shifter has further travel that is used
to reach the GM park position but is not
used on Chrysler transmissions. Trying to
force the shifter will damage the cable.)
The shift lever on the transmission should
be all the way back. 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 shifter
through all gear positions. Check to make
sure swivel will slide in and out of the
selector lever hole in each gear position.
Install cotter key supplied with shifter into
swivel and spread key ends.
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.
IMPORTANT: Do not froce the shifter to
over travel into the Park position. This will
move the shifter into GM Park position and
will damage the cable or transmission.
STEP 25. Check operation of throttle link-
age again. Linkage must operate smoothly
with no bind. All transmissions using auto-
matic valve bodies must have the throttle
linkage connected and operating or trans-
mission damage will result.
STEP 26. Neutral Safety/Backup Light
switch.
’66-’68: The Neutral safety switch will con-
tinue to function normally. It will not be
necessary to hook up the Neutral safety
switch wires on the shifter. Disconnect the
battery ground cable before wiring the
Backup light switch. Locate the original
Backup Light switch on the steering col-
umn or console shifter. Run these wires to
the top switch on the B&M Megashifter,
See figure 1. Reconnect ground wire and
check light for proper operation. Adjust
switches on the shifter if required.
’69 and Later: The Neutral Safety/Backup
switch is located on the transmission and
will continue to function normally. It will not
be necessary to connect any wires to the
switches on the shifter.
STEP 27. Check operation of throttle link-
age again. Linkage must operate smoothly
with no bind. All transmissions using auto-
matic valve bodies must have the throttle
linkage connected and operating or trans-
mission damage will result.
STEP 28. Neutral Safety/Backup Light
switch.
’66-’68: The Neutral safety switch will con-
tinue to function normally. It will not be
necessary to hook up the Neutral safety
switch wires on the shifter. Disconnect the
battery ground cable before wiring the
Backup light switch. Locate the original
Backup Light switch on the steering col-
umn or console shifter. Run these wires to
the top switch on the B&M Light Truck
Megashifter, see figure 1. Reconnect
ground wire and check light for proper
operation. Adjust switches on the shifter if
required.
’69 and Later: The Neutral Safety/Backup
while the other touches the tower, see
figure 9. Using the dividers, scribe a line
around the tower that follows the contour
of the floorboard. Remove the tower and
trim at the scribe line using tin snips. Once
tower is properly trimmed, install it using
two flat head sheet metal screws. The
indicator cable should be routed out the
top of the tower on the right side while the
tower is being installed.
STEP 31. Install the indicator light bulb in
its socket on the shifter cover plate. Run a
length of wire from the vehicle’s instrument
light circuit to one of the wires. Connect the
other wire to a good chassis ground. A
shifter mounting bolt should be satisfac-
tory.
STEP 32. Snap shift position window into
cover plate. Window snaps in from the top
with tabs inserting into slots at either end of
window opening. Place shifter in the Park
position then remove T-Handle from shifter.
Place cover plate over the stick and onto
the top of the tower. Route the indicator
cable as shown in figure 10. (If the cable is
not routed this way, the indicator may bind.
Run the shifter through all of the gears to
check the operation of the indicator. If the
indicator needs adjustment, loosen the
screws holding the indicator cable clamp
to the cover plate and slide the cable bracket
to adjust the indicator position. (Re-tighten
these screws carefully since they are
threaded into plastic.) Attach the cover
plate to the tower with four Phillips head
screws.
switch is located on the transmission and
will continue to function normally. It will not
be necessary to connect any wires to the
switches on the shifter.
STEP 29. Place tower over shifter mecha-
nism until the bottom edge of the tower
touches the floor. Put the shifter cover and
indicator cable through the opening in the
top of the tower. Hold the tower level to the
shifter with the bottom of the tower touch-
ing the highest surface on the floor it will
come into contact with, see figure 9. Use
a ruler to measure the distance X from the
underside of the tower to the tower mount-
ing brackets on the shifter mechanism.
STEP 30. Set a pair of dividers at the dis-
tance X, measured in step 29. Hold the
tower level to the shifter mechanism with
the bottom of the tower touching the high-
est surface on the floor it will come into
contact with. Holding the tower in position,
place one leg of the divider against the floor

IMPORTANT
Before installing the T-handle onto
the shifter put a little grease on the
threads of the stick. The aluminum of
the T-handle may gall on the threads
of the stick and make it impossible to
remove the T-handle from the stick. If
this occurs it can cause the stick to
break if you use excessive force while
attempting to remove the T-handle
from the stick.
