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 Pro-
Lever 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.
