9500663-05 Printed in the U.S.A.
The B&M Pro Ratchet Shifter is a full
ratchet shifter that is equally at home on the
strip and on the street. It will work with most
two speed, three speed or four speed auto-
matic transmissions. It has a positive ratchet
design so that you will not miss a shift, either
up or down. It works with both standard and
reverse pattern valve bodies. It has a unique
“one hand” reverse lockout feature that meets
NHRA and IHRA requirements. You don’t need
to use two hands to shift into Reverse.
Part #80840 is for use only with aluminum
Powerglide transmissions. The supplied
B&M Powerglide Pro-Lever is for use
with full manual valve bodies or
transbrakes applications only. Part #80842
is for use with three speed automatic trans-
missions such as the GM TH-400, TH-350, TH-
250 and TH-200; the Ford C-4 and C-6; and the
Chrysler 1966 and later Torqueflite A-727 and
A-904, or four speed automatic transmissions
such as the GM TH-200 4R, TH-700 R4, 4L60,
4L60E and 4L65E; the Ford AOD; and the
Chrysler A-500 and A-518. To use the B&M
Pro Ratchet Shifter with the Ford AOD
transmissions you will need the optional ac-
cessory kit #40496.To use the B&M Pro
Ratchet Shifter with the GM 4L60E or 4L65E
equipped with a PRNDL switch you will need
optional accessory kit #75498 otherwise you

and a five foot shift cable. Optional shifter
cables in 2 ft. (#80830),3 ft. (#80831), 4 ft.

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.
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
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
four speed automatic transmission, you must
remove the three speed limiter blocker pin and
the e-clips indicated in Figure 1. Removing this
blocker pin gives the shifter four forward
positions rather than three. For Ford AOD four
speed automatic transmissions and Chrysler
A-500 and A-518 four speed automatic trans-
missions do not remove this blocker pin, since
these transmissions have only three forward
positions. Also do not remove the blocker pin
and the e-clips for any three speed automatic
transmissions. (The three speed limiter blocker
pin goes in the upper of the two holes at the
rear of the shifter and the two speed limiter
blocker pin goes in the lower hole).
If you are installing this shifter with a Ford
or Chrysler three or four speed automatic
transmission you must install the Park limiter
blocker pin and the e-clips as also indicated in
Figure 1. This limiter limits the shifter travel into
the Park position, so that it does not stretch the
cable since Ford and Chrysler transmissions
have less travel between Reverse and Park
than GM transmissions do.
STEP 1. Remove the stock shift linkage;
Column Shifters: Remove all rods, levers or
cables from the column and the transmission.
Place the column shift lever in the Park position.
Remove the pin holding the shift lever in the
column and remove the lever assembly. If your
vehicle is equipped with a locking steering
column, secure the column lock lever in the full
up position. WARNING: This allows the steer-
ing 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.
Console Shifters: Remove the shifter mecha-
nism from the console. Disconnect the rod or
the cable from the transmission. Remove the
cable bracket if equipped. If there is a cable or
linkage from the console shifter or transmis-
sion to the steering column lock, it must be
blocked in the Park position as described
above.
NOTE: Installation of the shifter may require
console modification or complete console re-
moval depending on the space available in
your vehicle.
