STEP 1. Disconnect the throttle to transmission linkage,
if any and discard. The Powerglide shift lever supplied with
this kit has no provision for a throttle linkage.*
STEP 2. Drain the transmission oil pan. Caution: Be sure
the transmission is cool before attempting to drain the oil.
Place a drain pan under the transmission. Remove 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 toward
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 3. Remove the manual valve guide plate by removing
two bolts (See Figure 1). 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 4. 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 5. Loosen the pinch bolt on the selector lever. This
can be either an Allen head bolt or 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 6. This kit includes the B&M Powerglide ProLever shift lever, which is a two piece lever with separate
lever and shaft. Install the B&M selector shaft into the
transmission with the lever pointing down. Hold the stock
selector 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 7. Install the manual valve guide plate in place.
(Make sure that pin on selector lever is engaged in the
groove in the manual valve.) Install the two bolts and tighten
to 15 lbs.ft. Install the detent roller spring. Hook the spring
to 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 8. Clean the oil pan and scrape the old gasket off of
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 left side of the pan.
Thighten the pan bolts to 8 lbs.ft. Do not overtighten as this
can damage the pan gasket.
STEP 9. Install the cable bracket in position with the two
remaining pan bolts (See Figure 1). 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 10. Remove the two rubber boots, one large nut, and
a large lockwasher from the threaded end of the shifter
cable. Avoid sharp bends and route the cable away from
*WARNING
This kit is intended for transbrakes or full manual valve bodies only. If your transmission requires throttle
linkage, you cannot use this kit.

hot engine and exhaust parts. The cable may be secured
up out of the way with nylon cable ties. Slide the end of the
cable into the cable bracket, install the lockwasher and the
large nut over the end of the cable. Position the cable so
the threaded portion of the cable housing is centered in the
cable bracket. Tighten both the large nuts to hold the cable
in this position. Install the two rubber boots onto the end of
the cable.
STEP 11. Move the transmission selector lever by hand to
full rear position (Low). Place the shifter lever to the full rear
position (Low gear with a forward pattern valve body).
Adjust the large nuts on the cable so that the swivel will
slide into the hole on the selector lever that is correct for
your shifter (See Figure 2). Tighten the large nuts completely. Be sure that the swivel will slide freely in an out of
the hole in the selector lever. Note: The shifter will not
operate correctly unless the correct hole for your shifter 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 the Park position (all the way forward).
Reinsert the swivel into the 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
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 correct hole in the lever, it will be impossible to
correctly adjust the cable.) Operate the shifter through all
the gear positions. Check to make sure the swivel will slide
in and out of the rear selector lever hole in each gear
position. The shift cable is now correctly adjusted. Install
the cotter key into the swivel and spread the key ends.
WARNING
Periodic inspection and maintenance of your shifter is recommended to ensure that the mechanism is well lubricated, free from dirt or rust
and that the cable is properly adjusted. Lack of maintenance could result in a failure, including a failure of the reverse lockout safety feature.
