B&M 50442 TORK MASTER 3000 C4 26 SPLINE 10.5 - Manual (Page 2)

You may lose some of the needle
bearings if the cups fall on the ground.
It is a good idea to tape the cups to the
U-joint cross, so they won’t fall off.
Now is a good time to clean and in-
spect your U-joints.
STEP 3. Disconnect vacuum line to
vacuum modulator. Disconnect
kickdown linkage. (See Figs. 1&2)
Remove clip holding rod or cable to
kickdown lever and allow rod or cable to
hang free. Disconnect shifter:
Column Shift Models: Disconnect
rod or cable from shift lever on trans-
mission. (See Fig. 1) The rod or
cable is retained by a clip or by
snapping into a plastic grommet.
Remove clip or pry rod out of grom-
met and allow linkage to hang free.
Cable models; unbolt cable bracket
from bell housing and allow cable to
hang free.
Console Shift Models: Disconnect
rod from shift lever on transmission.
(See Fig. 2) The rod is retained by a
clip or by snapping into a plastic
grommet. Remove clip or pry rod out
of grommet and allow linkage to hang
free.
'70 and Later Vehicles Equipped
With Locking Steering Column And
Console Shifter: Disconnect col-
umn lock rod from transmission shift
lever and allow it to hang free.
4 Wheel Drive Models: Remove
knob from transfer case shift lever.
STEP 4. Loosen and disconnect speed-
ometer cable:
Clamp Type Cable: Remove bolt or
speedometer cable clamp. Pull
speedometer cable out of extension
housing and let it hang free.
Sleeve Type Cable: Loosen cable
sleeve. Pull speedometer cable out of
speedometer housing and let it hang
free.
STEP 5. Disconnect oil cooler lines.
Use a fitting wrench, if available, to avoid
damage to compression nuts. We
recommend that the oil cooler lines be
flushed out to remove any foreign par-
ticles trapped in the cooler. Cooler lines
should be flushed in both directions with
solvent and air pressure.
STEP 6. Remove dipstick and tube
assembly. Remove torque converter
access cover bolts and remove con-
verter access cover. Remove flexplate
to converter nuts. Use starter motor to
“bump” each bolt into position.
STEP 7. Disconnect neutral safety
switch on vehicles equipped with neu-
tral safety switch mounted on the trans-
mission by unplugging connector ends
on wire harness. Allow connector ends
to hang free.
STEP 8. Remove starter motor assem-
bly and tie it up out of the way. On some
vehicles, it is difficult to remove the
starter completely, so it is easier to
simply support it out of the way.
STEP 9. Support the transmission with
a jack. Remove the transmission rear
mount bolts. Raise the transmission
slightly and remove the crossmember.
Be sure the transmission jack supports
the transmission on a wide area so you
don’t crush the oil pan.
STEP 10. Remove the bellhousing
bolts. Lower transmission until the
engine is supported. Pull transmission
back slightly away from engine. Make
sure converter stays with transmission.
Lower transmission/converter assem-
bly and remove from vehicle. Caution:
4 Wheel Drive Vehicles: Transmis-
sion/converter transfer case assembly
is heavy. Exercise care during removal
if your transfer case bolts to the trans-
mission.
STEP 11. Pull converter off the front of
the transmission. Some oil will leak
out at this time. On C-4, C-6 and AOD
transmission, the input shaft may pull
out of the transmission when you re-
move the torque converter. Do not be
alarmed.
C-4: Install the short splined end
of the input shaft into the transmis-
sion until the splines engage the
drum inside the transmission. Push
the shaft in all the way until it stops.
C-6: Install the long splined end of
the input shaft into the transmission
until the splines engage the drum
inside the transmission. Push the
shaft in all the way until it stops.
Important C-4 ONLY: C-4 transmis-
sions have either a 24T or 26T (Early &
Late models) spline input shaft. Re-
move the input shaft and insert it into
your B&M converter. Be sure that the
input shaft engages the spline inside of
the torque converter and is a good fit
into the spline. Install input shaft into
transmission as previously described.
STEP 12. Inspect your engine block
and engine plate. Make sure there are
no burrs that will prevent the transmis-
sion from bolting down flat against the
engine. File off any burrs that may be
present. Dowel pins should stick out of
the engine block a minimum of 1/2" for
proper alignment. (See Fig. 3) Insuffi-
cient dowel pin engagement can cause
front seal and/or bushing failure due to
improper engine/transmission align-
ment. Bellhousing bolts alone will
not align the transmission properly.
