B&M 80694 CONSOLE MEGASHIFTER - Manual

Printed in U.S.A.
9500453-07
This B&M Megashifter shifter is de-
signed to fit in the consoles of 1973-81
Chevrolet Camaros and 1970-81 Pontiac
Firebirds equipped with three speed au-
tomatic transmissions. The shifter is
equipped with neutral start and backup
light switches and a five foot shift cable.
The installation is the same for either
shifter.
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.
INSTALLATION:
NOTE: If you are installing this shifter with
a GM four speed automatic transmission
you must remove the blocker pin and the
two e-clips indicated in Figures 2 and 3.
Removing this blocker pin gives the shifter
four forward positions rather than three.
Do not remove the blocker pin and the two
e-clips for three speed automatic trans-
missions.
To install this shifter on a 4L60E or
4L65E equipped with a PRNDL switch
you will need B&M installation kit
#75498, otherwise use supplied GM
bracket.
STEP 1. Remove the console from the
car (See Figure 1). Remove the two
screws inside the storage box, two under
the storage box and two in the dash
board. Remove the four screws on the
shifter cover plate.
STEP 2. Disconnect the stock shifter
cable then remove the cable bracket and
the selector lever from the transmission
(See Figure 4). Remove the shifter mecha-
nism. Remove the shifter cable from the
vehicle.
STEP 3. If there is a torque shaft con-
nected to the shift lever on the side of the
transmission that interlocks the shifter
with the steering column lock, this torque
shaft and the link from the shaft to the
bottom of the steering column must be
removed. The link on the bottom of the
steering column must be wired in the
Park position (usually fully up) so that the
steering column lock will work and will
allow the key to be removed. After wiring
the lever in this position, check to see that
the steering column lock works correctly,
and that you can remove the key. WARN-
ING: With the interlock disabled in this
manner it is possible to lock the steer-
ing column at any time, so be careful not
to turn the key to the “LOCK” position
while the car is moving.
STEP 4. Assemble the neutral safety
and reverse light switches to the bracket
using two #4-40 x 1-1/4" screws, two 4-40
lockwashers, and two 4-40 hex nuts, as
shown in Figure 2. Beware, over tighten-
ing the switch attachment screws will
crack the switch housings. To adjust the
switches loosen the screws and slide
the switches in or out as required, then
re-tighten the screws. STEP 5. Install the cable on the shifter
as shown in Figure 2. The cable attach-
ment tab should be bolted to the outside
surface of the shifter base using a 1/4-20
x 3/4" hex screw, 1/4" lockwasher, and
1/4-20 hex nut. Install the large e-clip that
secures the cable to the cable pin.
STEP 6. Bolt the B&M bracket to the
shifter with four 1/4-20 x 3/4" hex screws,
four 1/4" lockwashers, four 1/4" washers,
and four 1/4" hex nuts.
Install the B&M mounting bracket and
shifter assembly to the floor using the
four stock screws (See Figure1).
(Note: Bracket to shifter screws may need
to be inserted from the bottom if screw
clearance issues are encountered.)
STEP 7. Just before the final installa-
tion of the shifter in the vehicle, attach the
indicator cable to the side of the shifter as
shown in Figure 3. The indicator cable
bracket is secured to the shifter mecha-
nism with two 6x1/4" tapping screws and
two #8 washers, the eyelet on the end of
the indicator cable is secured to the cable
pin by a supplied small e-clip. The B&M
top cover plate with the gear position
indicator is attached to the other end of
the indicator cable.
STEP 8. Route the shifter cable as
shown in Figure 4. Avoid sharp bends
that will kink and damage the cable.
STEP 9. Install the B&M selector lever in
position on the transmission using the
stock selector lever nut (See Figure 5).
Torque the nut to 23 lb.ft. The lever should
move smoothly front to back with a posi-
tive click in each gear position.
STEP 10. Remove the two transmission
oil pan bolts from the middle of the left
side of the oil pan. Install the cable bracket
