so, loosen the pinch bolt on the throttle
lever on the transmission. This is the
lever on the small diameter shaft. Pry the
lever off with a screwdriver and allow the
linkage to hang free. Remove and dis-
card the stock shift lever and the stock
shift linkage. Install the B&M selector
lever in position and tighten the pinch
bolt securely (See Figure #6). Make sure
the lever is not pushed down so far as to
touch the transmission case. This will
cause the lever to bind on the case. The
lever should travel smoothly from front to
back with a positive click in each gear
position. Install the stock throttle lever in
position on the small diameter shaft as
removed and tighten the pinch bolt se-
curely. The throttle lever must operate
smoothly.
STEP 20. Remove the two transmission
oil pan bolts directly below the shift lever.
Install the cable bracket in position (See
Figure #6) with two spacers between the
pan and the bracket. (If your transmis-
sion is equipped with a cast aluminum
oil pan these spacers can be omitted.)
Install the two 5/16-18 x 1.00" pan bolts
supplied and tighten to 12-13 ft. lbs. Do
not overtighten as this can damage the
pan gasket.
STEP 21. Remove two rubber boots, one
large nut, and a large lockwasher from
the threaded end of the shifter cable.
Route the shifter cable according to Fig-
ure #2. Avoid sharp bends and route the
cable away from 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 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 large nuts to hold the cable
in this position. Install the two rubber
boots onto the end of the cable.
STEP 22. Move the transmission selec-
tor lever by hand to the full forward posi-
tion (Low). Place the shifter lever to the
Low gear position (ratcheted all the way
back). 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,
move the shifter to the Park position, as
far forward as the shifter will go without
forcing it. (The shifter has further travel
that is used to reach the GM Park posi-
tion but is not used on Chrysler trans-
missions. Trying to force the shifter will
damage the cable.) The shift lever on the
transmission should be all the way back.
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 the Low
and Park positions. Operate the shifter
through all the gear positions. Check to
make sure swivel will slide in and out of
the selector lever hole in each gear po-
sition. Install the cotter key supplied 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 transmis-
sion. Simply start at the beginning and
carefully check all your steps.

IMPORTANT
Before installing the T-handle onto
the shifter put Loctite on the threads of
the stick. The T- Handle may gall on
the threads of the stick and make it
impossible to remove the handle from
the stick. If this occurs it can cause the
stick to break if you use excessive
force while attempting to remove the
knob from the stick.
IMPORTANT: Do not force the shifter to
over travel into the Park position. This
will move the shifter into GM Park posi-
tion and will damage the cable or the
transmission.
STEP 23. Check the operation of the
throttle linkage again. The linkage must
operate smoothly with no bind. All trans-
missions using automatic valve bodies
must have the throttle linkage connected
and operating or transmission damage
