B&M 80690 MEGASHIFTER - Manual

The B&M Megashifter shifter can
be used in vehicles equipped with most
popular three speed or four speed au-
tomatic transmissions. Your B&M Me-
gashifter comes equipped with neu-
tral safety and backup light switches,
transmission brackets and levers and
a five foot shift cable. Optional shifter
cables in 2 ft. (#80830), 3 ft.(#80831),
4 ft.(#80832), 8 ft.(#80834), 10
ft.(#80835) and 12 ft. (#80836) are also
available. To use the B&M Megashift-
er with the Ford AOD transmissions
you will need the optional accessory
kit #40496. To use the B&M Megash-
ifter with a GM 4L60E or 4L65E trans-
mission equipped with a PRNDL switch
you will need the optional accessory
kit #75498 otherwise you can use the
GM bracket supplied.
Please read the instructions and
review the illustrations thoroughly be-
fore beginning the installation.
The mechanical components of this
shifter are precision made and as-
sembled at our factory. Any modifica-
tion or disassembly of these parts can
cause the shifter to malfunction and
will void the warranty. You should dis-
assemble only those items outlined in
the instructions.
The vehicle should be about 2 feet
off the ground for ease of installation.
Use jack stands, wheel ramps or a
vehicle lift. Make sure the vehicle is
firmly supported before attempting to
work on it.
IMPORTANT: If your vehicle is equipped
with a locking steering column, secur-
ing the column lock lever in the engine
compartment in the full up position will
allow the steering wheel to be locked
and unlocked and the ignition key to be
removed.
WARNING: This allows the steering
wheel to be locked WHENEVER the
ignition key is turned to the “lock”
position WHILE THE VEHICLE IS MOV-
ING, OR AT ANY OTHER TIME. Se-
curing the steering column lock lever in
any other position will both PREVENT
the steering wheel from locking and
removal of the ignition key.
INSTALLATION
NOTE: If you are installing this shifter
with a four speed automatic transmis-
sion, you must remove the blocker pin
and the two e-clips indicated in Fig-
ures 1 and 3. Removing this blocker
pin gives the shifter four forward posi-
tions rather than three. For Ford AOD
four speed transmissions do not re-
move this blocker pin and the two e-
clips, since this transmission has only
three forward positions. Also do not
remove the blocker pin and the two e-
clips for three speed automatic trans-
missions.
STEP 1. Remove the stock shift link-
age;
Column Shifters: Remove all rods,
levers or cables from the column and
the transmission. Place the column
shift lever in the Park position. Remove
the pin holding the shift lever in the
column and remove the lever assem-
bly. If your vehicle is equipped with a
locking steering column, secure the
column lock lever in the full up position.
WARNING: This allows the steering
wheel to be locked and ignition key
removed WHENEVER the ignition key
is turned to the “lock” position WHILE
THE VEHICLE IS MOVING, OR AT
ANY OTHER TIME.
Console Shifters: Remove the shifter
mechanism from the console. Discon-
nect the rod or the cable from the
transmission. Remove the cable
bracket if equipped. If there is a cable
or linkage from the console shifter or
the transmission to the steering col-
umn lock, it must be blocked in the
Park position as described above.
NOTE: Shifter installation may require
console modification or complete con-
sole removal depending on the space
available in your vehicle.
STEP 2. Pull the carpet away from the
floorboard where the shifter is to be
mounted. If the vehicle has a bench
type seat, move the seat to the full
forward position. Place the shifter on
the floor with the stick shifted to the
rearmost gate position. Locate the
shifter for ease and convenience of
operation (See Figure 2). Make sure
the trigger and T-handle clear the dash
with the shifter in the Park position.
Mark the position of four mounting
holes on the floor.
STEP 3. Drill four 9/32" mounting holes
where marked. Temporarily mount the
shifter in place using washers as re-
quired to get it level. Do not bend the
mounting brackets on the bottom
of the shifter. Mark the location for the
shifter cable hole, 3" ahead of the left
front shifter mounting hole. Drill or cut
a 1-1/2" diameter cable hole in the
floorboard. NOTE: Some floorboards
are extremely thin and will not ad-
equately support the shifter mecha-
nism when bolted to the floor. For
those vehicles we recommend that
you fabricate a stiffener plate for addi-
tional strength.
