B&M 80692 CONSOLE MEGASHIFTER - Manual

Printed in U.S.A. 9500452-09
This B&M Megashifter is designed to fit
in the consoles of 1982-1992 Chevrolet
Camaros and Pontiac Firebirds*. In 1982 these
vehicles were equipped with three speed
automatic transmissions. Since 1983 they
have been equipped with four speed auto-
matic transmissions. Shifter #80692 is for
three speed automatic and four speed auto-
matic transmissions. The shifters are equipped
with neutral start and backup light switches
and a five foot shift cable. If the shifter is used
with the four speed automatic transmission
(TH-700-R4,4L60, 4L60E, or 4L65E), the
blocker pin and E-clips shown in Figures #2
and #3 must be removed.
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.
Please read the instructions and review
the illustrations thoroughly before beginning
the installation.
The mechanical components of this shifter
are precision made and assembled at our
factory. Any modification or disassembly of
these parts can cause the shifter to malfunc-
tion 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
STEP 1. Remove the knob from the stock
shifter. Pull firmly up on the detent button and
it will pop out. Remove the snap ring inside of
the knob and pull off the knob.
STEP 2. Remove the top cover of the con-
sole. On the Camaro remove six screws
(some of the screw heads on the cover plate
may be dummy screws) and on the Firebird
remove four exterior screws and one in the
ashtray. Remove the console light from the
cover.
STEP 3. Disconnect the two cables from
the shifter. The left hand cable is the shift
cable and the right hand cable is the Park lock
cable. Remove the wiring plug from the shifter
body. Unbolt and remove the shifter mecha-
nism (See Figure #1). Remove the cable
bracket and the selector lever from the trans-
mission (See Figure #4). Remove the shift
cable from the vehicle.
STEP 4. The Park lock cable must be wired
in the Park position (fully in) so that the
steering column lock will work and will allow
the key to be removed. The cable should also
be secured inside of the console out of the
way. After wiring the cable in this position
check to see that the steering column lock
works correctly, and that you can remove the
key. WARNING: With the interlock dis-
abled in this manner it is possible to
lock the steering column at any time, so
be careful not to turn the key to the
“LOCK” position while the car is mov-
ing.
STEP 5. Assemble the neutral safety and
reverse light switches to the bracket using
two #4-40 x 1" screws and nuts, as shown
in Figure #2. Beware, over tightening the
switch attachment screws will crack the
switch housings. Install the switch assembly
on the shifter. To adjust the switches, loosen
the screws and slide the switches in or out
as required, then retighten the screws.
STEP 6. Install the cable on the shifter as
shown in Figure #2. The cable attachment
tab should be bolted to the outside surface
of the shifter base using 1/4" x 1/2" hex bolt,
lock washer and nut. Install the E-clip that
secures the cable to the cable pin.
STEP 7. Install the B&M rear mounting
bracket to the floor (See Figure #1). Bolt the
front mounting bracket to the front of the
shifter. Put the shifter on the rear bracket and
put the bolts in finger tight. Using the slots in
the front mounting bracket as a guide, mark the positions on the floor pan for the front
mounting bolts. Remove the shifter and drill
two 9/32" holes for the front mounting
screws. Replace the shifter guiding the cable
through the hole and rubber seal in the floor.
Bolt the shifter in place.
STEP 8. Just before the final installation of
the shifter in the vehicle, attach the indicator
cable to the side of the shifter as shown in
Figure #3. (The other end of the indicator
cable is attached to the B&M cover plate.)
The indicator cable bracket is secured to the
shifter mechanism with two #6 x 3/8" sheet
metal screws and two #6 washers, the
eyelet on the end of the indicator cable is
secured to the cable pin by a supplied small
E-clip. If the shifter is being used with the four
speed automatic transmission, the blocker
pin and E-clips shown in Figures #2 and #3
must be removed.
STEP 9. Route the shifter cable as shown in
Figure #4. Avoid sharp bends that will kink
and damage the cable.
STEP 10. 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 ft. lbs. The lever should move
smoothly front to back with a positive click in
each gear position.
STEP 11. Remove the two transmission oil
pan bolts from the middle of the left side of the
oil pan. Install the cable bracket in position
(See Figure #5). The bracket must be in-
stalled with spacers between the pan and the
bracket. Install the two 5/16x1.00" bolts (or
M8x25 mm for metric transmissions) supplied
and tighten 12-13 ft. lbs. Do not overtighten as
this can damage the pan gasket.
STEP 12. Route the shifter cable according
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
