end of the shifter cable. Slide the end of the
cable into the cable bracket. Install the large nut
and the lockwasher loosely over the end of the
cable. Install the two rubber boots onto the end
of the cable. Install the swivel on the threaded
end of the cable and position it in the center of
the threaded portion.
STEP 22. Be sure that the Park limiter blocker
pin and the three speed limiter blocker pin are
both installed as shown in Figure 1. The Park
limiter will prevent the shifter from additional
travel beyond the Chrysler Park position. (GM
transmissions have greater travel between
Neutral and Park than Chrysler transmissions
do). The three speed limiter blocker pin is
required because all Chrysler three and four
speed automatic transmissions have only three
forward gear positions, even the four speed
A500 and A518.
Move the transmission selector lever by
hand to the full rear position (Low). Shift the
shifter mechanism to the Low gear position
(ratcheted back until it is stopped by the three
speed limiter blocker pin). 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, shift
the shifter to the Park position, as far forward
as the shifter will go without forcing it. (The
Park limiter blocker pin will prevent the shifter
from moving any further). 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 the
shifter through all the gear positions. Check to
make sure the swivel will slide in and out of the
drain plug, if so equipped. If your pan does not
have a drain plug, remove the oil pan bolts one
at a time, working towards the front. As you
loosen the last two bolts, the oil pan will tilt
down and allow the oil to drain. Note: If your oil
pan sticks to the gasket, pry it down with a
screwdriver before loosening the last two
bolts to break it free. Remove the oil pan and
set it aside.
Step 27. Remove the manual valve guide
plate by removing the two bolts (See Figure
8). Unhook and remove the detent roller spring.
Allow the detent roller to pivot out of the way.
Note how the pin on the manual valve selector
engages the groove in the manual valve.
STEP 28. If your transmission has a throttle
valve lever on the outside of the shift lever,
loosen the inner pinch bolt on the throttle lever.
Slide the throttle lever and the shaft out of the
transmission. Remove the inner throttle valve
lever. Discard these parts.
STEP 29. Loosen the pinch bolt on the selec-
tor lever. This can be an Allen head bolt of a 12
point bolt head. Do not remove the pinch bolt.
Slightly pry the manual valve lever and slide the
selector shaft from the transmission. Discard
the selector shaft.
STEP 30. This shifter includes the B&M Pow-
erglide Pro-Lever, which is a two piece lever
with a separate lever and shaft. Install the
B&M selector shaft into the transmission with
the lever pointing down. Hold the stock selec-
tor lever in position in the case, engage the pin
on the selector lever with the manual valve and
rotate the B&M shaft until the flat on the shaft
engages the serrations on the lever. Push the
B&M lever firmly into the transmission until the
lever stops on the shoulder of the shaft.
Tighten the pinch bolt securely.
STEP 31. Install the manual valve guide plate
in place. Make sure that the pin on the
selector lever is engaged in the groove
in the manual valve. Install the two bolts and
tighten to 15 lb. ft. Install the detent roller spring.
Hook the spring to the detent roller and the tab.
The selector lever must travel freely and
smoothly from front to back with a positive
click in each gear position.
STEP 32. Clean the oil pan and scrape the
old gasket off the pan and the case. (Note: if
your pan does not have a drain plug, you may
wish to install a B&M Drain Plug Kit #80250 at
this time). The old gasket can cause leaks.
Install the oil pan with a new gasket. Install the
pan bolts except for the two center bolts on the
left side of the pan. Tighten the pan bolts to 8
lb. ft. Do not overtighten as this can damage the
pan gasket.
STEP 33. Install the cable bracket into posi-
tion with the two remaining pan bolts (See
Figure 8). Install the B&M lever onto the shaft
with the lever pointing down. If your cable
comes from the front (usually a rear engined
car) the lever is installed pointing upwards.
You will have to make your own cable bracket
for this installation.
STEP 34. Route the shifter cable according
to Figure 3. Avoid kinks and sharp bends and
selector lever hole in each gear position. Install
the supplied cotter key with the shifter into the
swivel and spread the 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 23. Check the operation of the throttle
linkage again. The linkage must operate
smoothly with no bind. All transmissions using
automatic valve bodies must have the throttle
linkage connected and operating or transmis-
sion damage will result.
STEP 24. Neutral safety/backup light switch.
’66-’68: The neutral safety switch will con-
tinue to function normally. It will not be neces-
sary 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 the console shifter.
Run these wires to the UPPER switch on the
B&M Pro Ratchet Shifter (See Figure 1).
Reconnect the ground wire and check the light
for proper operation. Adjust the 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. Go to Step 37.
POWERGLIDE
STEP 25. Disconnect the throttle to transmis-
sion linkage, if any and discard. The Power-
glide shift lever supplied with this shifter has
no provision for a throttle linkage.
STEP 26. Drain the transmission oil pan. Cau-
tion: Be sure the transmission is cool
before attempting to drain the oil. Place a
drain pan under the transmission. Remove the
