Console Shifters: Remove the shifter

mechanism from the console. Discon-

nect the rod or the cable from the trans-

mission. Remove the cable bracket if

equipped. If there is a cable or linkage

from the console shifter or the transmis-

sion to the steering column lock, it must

be blocked in the Park position as de-

scribed above.

NOTE: The shifter installation may re-

quire console modification or complete

console removal depending on the space

available in your vehicle.

STEP 3. Assemble the mounting

bracket as shown in Figure 1. Be sure

that the end plate with the wide slot on top

is to the front and that the top plate has the

three holes at the front. Assemble the

bracket with the four 1/4-20 x 3/4" screws

finger tight. Put flat washers on both sides

of the brackets and a lock washer under

the nut.

Pull the carpet away from the floor-

board where the shifter mounting bracket

is to be located. Place the shifter on the

mounting bracket and slide the front and

rear brackets up or down to get the de-

sired height for the shifter. Tighten the

four screws on the bracket. If the vehicle

has a bench type seat, move the seat to

the full forward position. With the stick

shifted to the rearmost gate position.

Locate the shifter for ease and conve-

nience of operation (See Figure 2). Make

sure the trigger and the T-handle clear

the dash with the shifter in the Park posi-

tion. Mark the position of four mounting

holes for the bracket assembly on the

floor.

STEP 4. Drill four 9/32" mounting holes

where marked. Temporarily mount the

shifter to the mounting bracket and bolt

the bracket to the floor. If the floor is not

flat, bend the tabs at the end of the front

and rear bracket. Mark the location for the

shifter cable hole in the floor. The hole will

be 1" inboard of the left front mounting

bracket to floor bolt and between 2-1/2"

The B&M Light Truck Megashifter

shifter is designed to be used in most

light trucks equipped with most popular

three speed or four speed automatic

transmissions. Your B&M Megashifter

comes equipped with neutral 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 Light Truck Megashifter with the

Ford AOD transmissions you will need

the optional accessory kit #40496.To use

the B&M Light Truck Megashifter with

the GM 4L60E and 4L65E equipped with

a PRNDL switch you will need optional

accessory kit #75498 otherwise you can

use the GM bracket supplied.

This shifter has adjustable height

mounting brackets so that it can be in-

stalled at the best height for your truck.

Because the front and rear mounting

brackets can be adjusted separately, it

can also be install on an angled or slop-

ing floor with the shifter mounted flat.

Please read the instructions and re-

view the illustrations thoroughly before

beginning the installation.

The mechanical components of this

shifter are precision made and as-

sembled at our factory. Any modification

or disassembly of these parts can cause

the shifter to malfunction and will void the

warranty. You should disassemble 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, securing

the column lock lever in the engine com-

partment in the full up position will allow

the steering wheel to be locked and un-

locked 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 MOVING, OR AT ANY

OTHER TIME. Securing the steering col-

umn lock lever in any other position will

both PREVENT the steering wheel from

locking and the removal of the ignition

key.

INSTALLATION

NOTE: If you are installing this shifter with

a GM four speed automatic transmis-

sion, you must remove the blocker pin

and the two e-clips indicated in Figures

1 and 3. Removing this blocker pin gives

the shifter four forward positions rather

than three. For Ford AOD four speed

transmissions do not remove this blocker

pin and the two e-clips, since this trans-

mission has only three forward posi-

tions. Also do not remove the blocker pin

and the two e-clips for three speed auto-

matic transmissions.

STEP 1. Locate the shifter on the floor of

the truck where you want it to be located.

The mounting brackets can mount the

basic shifter assembly 1-1/2" to 3-5/8"

above the floor. Figure 2 gives the dimen-

sion of the shifter, so be sure that there is

enough room where you will be mount-

ing the shifter.

STEP 2. Remove the stock shift linkage;

Column Shifters: Remove all rods, le-

vers or cables from the column and the

transmission. Place the column shift le-

ver in the Park position. Remove the pin

holding the shift lever in the column and

remove the lever assembly. If your ve-

hicle is equipped with a locking steering

column, secure the column lock lever in

the full up position. WARNING: This al-

lows the steering wheel to be locked and

the ignition key removed WHENEVER the

ignition key is turned to the Lock position

WHILE THE VEHICLE IS MOVING, OR AT

ANY OTHER TIME.
