Part No. 80885 & 80887
©2010, 2006, 2005, 2004, 1999 by B&M Racing and Performance Products
(Visit www.bmracing.com for additional products and product information)
The B&M Hammer shifter can be used in
vehicles equipped with most popular three
speed or four speed automatic transmissions.
Your B&M Hammer 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 Hammer
with the Ford AOD transmissions you will
need optional accessory kit #40496. To use
the B&M Hammer with a GM 4L80E or 4L85E
transmission equipped with a PRNDL switch
you will need the optional accessory kit #75498
otherwise you can use the GM bracket supplied.
To use this shifter with a GM four speed
automatic transmission (TH-700R4, TH-200
4R, 4L60,4L80E or 4L85E) you will need to
remove the three speed blocker bolt and nut.
(See figures 1 and 3.) For the Ford AOD four
speed transmission do not remove this bolt.
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 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 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
Printed in the U.S.A.
MOVING, OR AT ANY OTHER TIME. Securing
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 GM
TH-700R4, TH-200 4R, 4L60, 4L80E or a
4L85E four speed automatic transmission you
must remove the bolt and nut indicated in
figures 1 and 3. Removing this bolt gives the
shifter four forward positions rather than
three. For Ford AOD four speed transmissions
do not remove this bolt and nut, since this
transmission has only three forward positions. Also do not remove the bolt and nut for
three speed automatic transmissions.
STEP 1. Remove stock shift linkage;
Column Shifters: Remove all rods, levers or
cables from column and transmission. Place
column shift lever in “Park” position. Remove
pin holding shift lever in column and remove
lever assembly. If your vehicle is equipped
with a locking steering column, secure the
column lock lever in the full up position. WARN-
ING: 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 shifter mechanism from console. Disconnect rod or cable
from transmission. Remove cable bracket if
equipped. If there is a cable or linkage from the
console shifter or transmission to the steering
column lock, it must be blocked in the “Park”
position as described above.
NOTE: Shifter installation may require console modification or complete console 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 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 required to get it
level. Do not bend mounting brackets on
bottom of shifter. Mark the location for the
shifter cable hole, 3" ahead of the left front
shifter mounting hole. Drill or cut 1-1/2" diameter cable hole in floorboard. NOTE: Some
floorboards are extremely thin and will not
adequately support the shifter mechanism
when bolted to the floor. For those vehicles we
recommend that you fabricate a stiffener plate
for additional strength.
STEP 4. Install (but do not secure) carpet
back to it’s original position. Cut holes in the
carpet for the mounting holes and cable. DO
NOT use a drill bit to make holes in carpet.
STEP 5. Assemble Neutral Safety and Re-
verse light switches to bracket using two #440 x 1" screws and nuts, as shown in figure
1. Beware, Over tightening the switch attach-
ment screws will crack the switch housings.
Install Switch assembly on shifter. To adjust
switches loosen screws and slide switches in
or out as required, then retighten screws.
STEP 6. Install cable on shifter as shown in
figure 1. 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-Ring that secures the
cable to the cable pin.
STEP 7. Before the final installation of the
shifter in the vehicle, add longer wires to the
indicator light (LED) and attach the indicator
cable to the side of the shifter. Attach longer
wires to the indicator light leads, use butt
splices or solder and tape the wires. The
extension wires should be color coded or
marked, since they must be connected with
the correct polarity. The black wire must go to
ground and the red wire must go to a 12 volt
positive (+) supply. The LED will not illuminate
if they are connected backwards. The red

wire must be connected to a source that is hot
when ever the ignition is turned on, since the
shifter indicator will not be visible, even in
daylight, unless it is illuminated. The ground
wire can usually go to one of the bolts that hold
the shifter to the floor. The hot wire will
probably have to go to the instrument panel.
After the wires are lengthened, slide the
indicator in the shifter top plate all the way to
the rear, the end away from the cable connection. Then tape the two wires to the indicator
cable just ahead of the cable mounting bracket.

Leave a little slack in these wires with the
indicator all the way to the rear. About 3”
further down the cable tape the wires to the
cable again. See figure 4.
Secure the indicator cable bracket to the
shifter mechanism with two #6 x 1/4" sheet
metal screws and #6 washers. (Do not use
longer screws in this position or they will
cause the mechanism to bind.) The eyelet on
the end of the indicator cable is secured to the
cable pin by a supplied small E-Ring, as shown
in figure 3.
STEP 8. Install shifter mechanism into vehicle. Slide shifter cable through carpet and
hole in floor. Bolt shifter down using four 1/4"
x 1-1/2" hex bolts and nuts. If required use 1/
4" washers as shims between the shifter
mechanism and floor to level shifter. ROUTE
CABLE AS SHOWN IN FIGURE 5, AVOID
SHARP BENDS WHICH WILL KINK AND DAMAGE CABLE. Use cable clamps or tie wraps
to secure the cable housing to chassis to avoid
contact with hot engine or exhaust system.
STEP 9. Seal the hole where the cable goes
through the floorboards to prevent air or water
leakage. A putty type sealer can be used. For
General Motors vehicles go to Step 10, for
Ford vehicles got to Step 15, For Chrysler
vehicles go to Step 21.
GENERAL MOTORS
STEP 10. If you have not already done so,
remove the stock selector lever nut and selector lever from the transmission. Discard stock
lever and stock shifter linkage. Install B&M
selector lever in position using stock selector
lever nut, (See figure 6). Torque nut to 23 lb.
ft. The lever should move smoothly from front
to rear with a positive click in each gear
position.
STEP 11. Remove two transmission oil pan
bolts from the middle of the left side of the oil
pan. Install cable bracket in position, (See
figure 6.) The bracket must be installed with
two spacers between the pan and bracket. (If
your transmission is equipped with a cast
aluminum oil pan, these spacers should be
omitted. With a TH-400 with a cast aluminum
oil pan the cable bracket may have to be
modified.) Install the two 5/16-18 x 1.00" bolts
(Metric transmissions use the two 8mm x
25mm bolts) supplied and tighten 12-13 ft.
lbs. Do not overtighten as this can damage
pan gasket.
Note: In some cases possible modification to the GM cable bracket might be
required for the 4L80E and 4L85E transmissions without the PRNDL switch.
Verify that selector lever does not grind
on cable bracket before moving on to
step 10.
STEP 12. Route the shifter cable according to
figure 5. 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 13. Move the transmission selector lever by hand to full rear position (LOW). Operate the shifter lever to the low gear position
(ratcheted all the way back). Adjust the large
nuts on the cable so that the swivel will slide

into the front 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. Note: The shifter
will not operate correctly unless the front
hole in the shift lever is used.
Leave the swivel out of the hole and move
the selector lever to PARK, all the way forward. Also move the shifter to PARK position
(all the way forward). Reinsert the swivel into
the front hole in the selector lever. Check to
see that the swivel will slide freely in and out
of the front hole in the selector 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.
Move the shifter back to the low gear

position and check that the swivel will still slide
easily in and out of the front hole in the selector
lever. (If you do not use the front hole in the
lever, it will be impossible to correctly adjust
the cable.) Operate shifter through all gear
positions. Check to make sure swivel will slide
in and out of the front selector lever hole in
each gear position. The shift cable is now
correctly adjusted. 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.
STEP 14. On GM vehicles the neutral safety
switch may be located on the shifter (steering
column or console), or it may be a mechanical
interlock in the steering column that prevents
the key from turning to the Start position
unless the shifter is in the Park or Neutral
position. Identify the type of neutral safety
system you have. If the key will not turn to the
Start position unless the stock shifter is in
Park or Neutral, you have a mechanical interlock type, otherwise you have a neutral safety
switch type. If you have a neutral safety
switch, locate the switch and identify the
neutral safety wires (engine will not crank
unless these wires are connected together).
With either type, disconnect battery ground
cable to prevent accidental shorts. If you have
a neutral safety switch, disconnect and extend both wires from the GM switch to the

switch on the shifter. If you have a mechanical
interlock cut the wire that goes from the start
position on the ignition switch to the solenoid
on the starter. This wire is usually a 10 or 12
gauge purple wire. Run wires from both ends
of the cut wire to the switch on the shifter. Put
slip on terminals on the ends of the lengthened
wire. Crimp terminals onto wires using a
crimping tool or pliers. Connect the wires to the
LOWER switch on the shifter. Identify the
wires for the backup lights and run them to the
UPPER switch on the shifter. Tape terminal
connections and all other connections to prevent shorts. Reconnect battery ground cable,
disconnect coil wire and set the parking brake.
Check switch operation by attempting to start
motor in each shifter position. The starter
must crank only when shifter is in the Park
or Neutral position. Adjust switches if re-
quired. Reconnect coil wire. Go to Step 27.
FORD
STEP 15. If you have not already done so,
remove the nut and lockwasher holding the
downshift linkage onto the downshift lever
shaft. The downshift lever is the outer lever on
C-4, C-5, C-6 and AOD transmissions. Pull
the lever off the shaft and allow the linkage to
hang free. Remove and discard stock shift
linkage rods. Some C-6 and all (late) C-4 and
C-5 transmissions have a Neutral safety/
Backup light switch on the transmission shift
lever. If your transmission is so equipped,
remove the two bolts holding the switch in
place and slide it off the shift shaft. Disconnect the switch at the factory plug and discard
it.
STEP 16. Install the B&M selector lever, See
figure 7 or 8. Note: The B&M lever must point
downward for proper operation. If the stock
shift lever on your transmission points down,
GM Transmissions
Figure 5
you will have to remove the lower part of the
stock arm by cutting it off to clear the B&M
lever, (See figure 8). Install B&M selector
lever onto shift shaft of transmission. Align
selector lever so when it points straight down
it travels equal arcs in both directions from
center, then tighten 1/4"-20 x 1 1/2" pinch bolt
and nut. The lever should travel smoothly
from front to back with a positive click in each
gear position. Make sure O-ring is in position
on downshift shaft and install downshift lever
in position on shaft. Install lockwasher and nut
and tighten securely. Downshift lever must
operate smoothly. Reconnect downshift linkage.
STEP 17. Cable bracket installation:
AOD: Instructions for the AOD are included
GM cable bracket
with the optional installation kit, Part No. 40496
C-4, C-5: Remove the two lower bolts from
the rear servo cover. Install cable bracket in
position, (See figure 7). Install two servo
cover bolts as removed and tighten 12-13 ft.
lbs. Do not overtighten as this can distort
servo cover.
C-6: Remove the two transmission oil pan
bolts from the left rear corner of the oil pan.
Install cable bracket in position, (See figure 8)
with two spacers between the pan and
bracket. (If your transmission is equipped with
a cast aluminum oil pan, these spacers can be
omitted.) Install the two 5/16-18 x 1.00" bolts
supplied and tighten 12-13 ft. lbs. Do not
overtighten as this can damage pan gasket.

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 19. Move the transmission selector lever by hand to full rear position (LOW). Place
the shifter lever to the low gear position
(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 Ford
transmissions. Trying to force the cable will
damage the cable.) The shift lever on the
transmission should be all the way forward.
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.

switches on the B&M Hammer. Locate and
identify the Neutral safety (the engine will not
crank unless these wires are connected together), and Reverse light wires. Disconnect
Battery ground cable before beginning to wire
the Neutral safety and Reverse light switches.
Reroute the wires to the B&M Hammer . Strip
1/4" insulation off wires and install supplied
slip-on terminals. Crimp terminals onto wires
using a crimping tool or pliers. Connect the
Neutral safety wires to the LOWER switch and
the Reverse light wires to the UPPER switch,
See figure 1. Tape terminal connections to
prevent shorts. Reconnect battery ground
cable, disconnect coil wire and set the parking
brake. Check switch operation by attempting
to start motor in each shifter position. The
starter must crank only when shifter is
in the Park or Neutral position. Check
Backup light operation when the shifter is
shifted to the Reverse position. Adjust switches
if required. Reconnect coil wire. Go to Step
27.

STEP 21. If you have not already done so,
loosen pinch bolt on throttle lever on transmission. This is the lever on the small diameter
shaft. Pry the lever off with a screwdriver and
allow linkage to hang free. Remove and discard stock shift lever and stock shift linkage.
Install B&M selector lever in position and
tighten pinch bolt securely, (See figure 9).
Make sure lever is not pushed down so far as
to touch the transmission case. This will cause
the lever to bind on the case. The lever should
travel smoothly from front to back with a

Throttle lever must operate smoothly.
STEP 22. Remove the two transmission oil
pan bolts directly below the shift lever. Install
cable bracket in position, (See figure 9). with
two spacers between the pan and bracket. (If
your transmission is equipped with a cast
aluminum oil pan these spacers can be omitted.) Install the two 5/16-18 x 1.00" pan bolts
supplied and tighten to 12-13 ft. lbs. Do not
overtighten as this can damage pan gasket.
STEP 23. Route the shifter cable according
to figure 5. 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 position
(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 force 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 linkage
again. Linkage must operate smoothly with no
bind. All transmissions using automatic valve
bodies must have the throttle linkage connected and operating or transmission damage will result.
STEP 26. Neutral Safety/Backup Light
switch.
’66-’68: The Neutral safety switch will continue 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 column or console shifter. Run
these wires to the top switch on the B&M
Hammer, 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. Place tower over shifter mechanism until the bottom edge of the tower touches
the floor. Hold the tower level to the shifter with
the bottom of the tower touching the highest
surface on the floor it will come into contact
with, (See figure 10). Use a ruler to measure
the distance X from the underside of the tower
to the tower mounting brackets on the shifter
mechanism.
STEP 28. Set a pair of dividers at the distance X, measured in step 27. Hold the tower
level to the shifter mechanism with the bottom
of the tower touching the highest surface on
the floor it will come into contact with. Holding
the tower in position, place one leg of the
divider against the floor while the other touches
the tower, (See figure 10). 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 a keyhole saw
or a saber saw. (The material is too thick to cut
6
Page 7
X
Figure 10
easily with tin snips.) Once tower is properly
trimmed, install the tower putting the shifter
top plate and indicator cable through the opening in the top of the tower. The indicator cable
should be routed around the front of the shifter
and out on the left side of the shifter while the
tower is being installed. See figure 11. Use
two flat head sheet metal screws to secure the
tower. The two wires for the indicator light
should be connected to a ground and to a
connection that is hot whenever the ignition is
on. The red wire on the LED must run to the
hot wire and the black wire must run to ground
or the LED will not light. Remember, the LED
must be illuminated anytime the ignition is on,
or you will not be able to tell what position the
shifter is in.
STEP 29. Install the top plate to the tower.
Feed the indicator cable into the tower and
then snap the top plate into the four slots in the
top of the tower. Snap shift position window
into top plate. The window snaps in from the
Route indicator cable around
front of backing plate and over
top of shift cable

top with tabs inserting into slots at either end
of window opening. Windows are provided
for both three speed and four speed transmissions.
STEP 30. Check the alignment of the indicator. Turn on the ignition to light the LED and
move the shifter through all positions to see if
the LED lights all of the gear positions on the
indicator. If the indicator is not correctly aligned,
IMPORTANT
Before installing the T-handle or
knob onto the shifter put Loc-tite on
the threads of the stick. The aluminum of the T-handle or knob may gall
on the threads of the stick and make
it impossible to remove the T-handle
or knob 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 or knob from the
stick.
remove the top plate, loosen the two screws
that secure the indicator cable to the tops
plate and slide the bracket forwards or backwards until the indicator is aligned. Tighten the
two screws carefully since they are threaded
into plastic. See figure 4. Snap the top plate
back onto the tower.
STEP 31. Remove the stick and trigger from
the shifter. Remove the two screws that secure the stick to the shifter and remove the
hitch pin that secures the trigger to the mechanism. See figure 12. Install the leather boot.
Turn the boot inside out and slide it over the
bottom of the stick. Put the stick back in place
on top of the mechanism, reinstall the two
screws and tighten. Slide the trigger back
through the stick and the steel trigger plate on
the shifter. Reinstall the hitch pin. Pliers are
the best tool for this installation.
STEP 32. Turn the boot right side out and
snap the boot into the top plate. Install the THandle or knob and jam nut. Tighten the jam nut
when the handle/knob is properly oriented. A
special jam nut is included with the shifter. It is
round with just two flats. The chamfered side
goes down. Use a little Loctite on the threads
to keep the handle/knob from turning. Check
the operation of the shifter.
If you want to have the logo in the THandle/knob paint filled to match the interior of
your car, follow these steps. Using masking
tape cover the T-Handle/knob leaving the logo
exposed as well as a 1/2" boarder around the
logo. Spray the handle with the desired color.
When the paint dries, remove the tape and
wipe off the overspray with lacquer thinner.
Be careful not to allow the wet rag to touch the
painted area inside the logo. A Q-Tip may be
helpful in the center of the logo for removing

OPERATION
The B&M Hammer normally functions as a
straight gate detent shifter from Park to Reverse to Neutral to Drive and as a ratchet
shifter from Neutral to all forward gears. Refer
to the following instructions for proper operation:
STRAIGHT GATE MODE: With the trigger in the upper position, the shifter functions
in the STRAIGHT GATE mode. The handle/knob
travels in a direct line forward and backward
from PARK to DRIVE. The trigger must be
raised up to clear the stop gates while going
through the gear positions.
RATCHET SHIFT MODE: The RATCHET
SHIFT mode allows firm, positive no-miss
upshifts and downshifts through all positions
from 1 (Low gear) to NEUTRAL. To switch
from STRAIGHT GATE to RATCHET operation, first operate shifter to the DRIVE position. The trigger will snap down approximately
3/4". The shifter is now in the RATCHET
MODE, DRIVE gear position. The shifter will
only operate in the RATCHET MODE between NEUTRAL and FIRST, it will not ratchet
to REVERSE or PARK. This is done to prevent accidental shifting into Reverse.
SHIFTING IN THE RATCHET MODE: Move
the shift handle/knob forward or backward
with a quick firm action until it hits the internal
stops, and allow it to spring return to the center
position. The shifter is now ready for the next
shift.
To switch the shifter from RATCHET MODE
back to the STRAIGHT GATE MODE, operate
the shifter to the DRIVE gear position, pull up
firmly on the trigger to engage the STRAIGHT
GATE MODE and move the handle/knob forward to NEUTRAL, REVERSE and PARK.
REMEMBER: To switch from the STRAIGHT
GATE MODE to the RATCHET MODE or from
RATCHET MODE to STRAIGHT GATE MODE
you must be in the DRIVE gear position. Refer
to the shift indicator gear position.
