route the cable away from hot engine or
exhaust parts.
Remove the two rubber boots, one
large nut, and a large lockwasher her 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 11. 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). Ad-
just the large nuts on the cable so that the
swivel will slide into the rear hole on the
selector lever. Tighten the large nuts com-
pletely. 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 rear 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 rear hole in the selector
lever. Check to see that the swivel will slide
freely in and out of the rear 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 rear hole in the
selector lever. (If you do not use the rear
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 rear
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 check all your steps.
STEP 12.
On GM vehicles, the Neutral
safety/backup light switch is located on the
console shifter or steering column. Locate
and identify the Neutral safety switch (the
engine will not crank unless these wires are
connected together). Disconnect Battery
ground cable before beginning to wire the
Neutral safety switch. Reroute the wires to
the B&M Pro Ratchet.
On GM vehicles the neutral safety switch
may be located on the shifter (steering
column or console), or it may be a me-
chanical 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

remove the stock selector lever nut and selec-
tor lever. Discard stock lever and stock shifter
linkage. Install B&M selector lever in position

Torque nut to 23 lb. ft. The lever should move
smoothly from front to rear with a positive click
in each gear position.
STEP 9. Remove two transmission oil pan
bolts from the middle of the left side of the oil
pan. Install cable bracket in position, see fig-
ure 4.) The bracket must be installed with two
spacers between the pan and bracket. (If your
transmission is equipped with a cast alumi-
num oil pan, these spacers should be omitted
however the cable bracket may have to be
modified.) Install the two 5/16-18 x 1.00" bolts
supplied and tighten 12-13 lb-ft. Do not over-
tighten as this can damage pan gasket.
STEP 10. Route the shifter cable according to
upper switch) operates in Reverse only by
loosening screws and sliding switch as re-
quired. Then retighten screws.
STEP 7. Install the shifter mechanism into
vehicle. Slide the shifter cable through carpet
and hole in floor. Bolt shifter down using four
¼” hex bolts and nuts. If required use ¼”
washers as shims between the shifter mecha-
nism and the floor to level shifter. Do not
bend the shifter mounting tabs. ROUTE
CABLE AS SHOWN IN FIGURE 3, AVOID
SHARP BENDS WHICH WILL KINK AND
DAMAGE CABLE. Use cable clamps or tie
wraps to secure the cable housing to the
chassis to avoid contact with hot engine or
exhaust system. Seal cable hole shut to
avoid the entry of exhaust fumes or water.
For General Motors vehicles with three speed
transmissions go to Step 8, For Ford ve-
hicles got to Step 13, For Chrysler vehicles
go to Step 19. For aluminum Powerglide
equipped vehicles go to Step 25.
