GENERAL
A
three speed synchromesh transmission is standard
equipment on all 'Jeep' Universal vehicles.
The
models T90 and T96 transmissions are used
with
the
Hurricane
F4 engine, and models
T86AA
and
T14A transmissions are used with the Daunt
less
V-6 engine. All model transmissions are similar
in
design with exception of the T14A which is a
fully
synchronized (all forward gears) transmission
with
helical drive gears throughout.
The
transmission assembly is attached to the
rear
face of the flywheel bell housing and is supported on a rubber insulator at the frame center cross member which forms the
rear
engine
support.
All
4-wheel-drive vehicles are equipped with a
transfer
case attached to the
rear
of the transmission.
Transfer
case service and repair procedures
are
described in Section
K.
Models
CJ-5A,
and
CJ-6A
are equipped with the
same transmission, but with a remote control shift.
Models DJ-5 and DJ-6 are equipped with a similar
transmission,
however, the construction is
some
what different because it is not designed to receive a transfer case for four-wheel drive.
For
DJ-5 and DJ-6 2WD vehicles, the trans mission repair procedures begin with Par. J-12.
J-2.
TRANSMISSION SHIFTING CONTROL
The
shift of the three-speed transmission is smooth
and
positive. The cane control lever shifts the trans
mission gears direct from the shift control housing
mounted to the top side of the transmission housing.
The
remote control lever shifts the transmission
gears through remote control rods attached to the
adjusting
levers of the shift shafts protruding from the left side of the transmission housing. Poppet
balls and springs retain the transmission gears in mesh and an interlocking mechanism prevents
shifting into two gears at the same time.
J-3.
Transmission Remote Control Adjustment
•
Early
CJ-5A,
CJ-6A
First
disconnect the transmission shift rods from the remote control levers.
Check
for binding of
the remote control shaft on the steering column
and
make the necessary corrections to eliminate any binding condition.
If
the shift is not smooth and positive, first make
sure
the gears are in neutral position then remove
the shift rods at the transmission by removing
clevis pins, Fig. J-l No. 17, and slip a short piece
of snug fitting 34" [6,35 mm.] aligning rod, through
the gearshift levers and housing as shown in insert
drawing.
This
places the clutch and shift lever assemblies
in
the neutral position. Adjust the shift rod yokes
at the transmission end, so clevis pins can be in stalled freely without moving the shift levers on the
transmission after which remove alignment pin.
If
shifting from first to second is difficult or trans
mission hangs in first gear, shorten the low and
reverse shift rod one
turn
at a time until the con
dition is corrected. Usually three turns are re
quired.
Should
the fault continue after completing the above adjustment, check further as outlined below.
First
remove the lubricating fitting. Use a narrow
feeler
gauge
which
will
enter the opening for the
lubricator
and check the clearance
between
the
faces of the shifting clutches.
This
clearance should
be .015" to .031", [W to W]
[0,397-0,794
mm.]. If
this clearance is greater the assembly must be removed for adjustment. The shift dog, which
engages
the clutch slots, should not have more than .009" [0,229 mm.] clearance in the slots. If the clear
ance
between
the clutch
grooves
and cross pins is
too great,
these
parts must be replaced.

Reassembly of
Remote
Control
•
Refer to
Fig.
J-l
Check
clearance of shift dog which
engages
in slot
of clutches, and if found to be greater than .009" [0,229 mm.] clearance, replace the worn parts.
Assemble upper clutch lever assembly in housing
making
sure that the alignment
hole
in the housing
faces toward the engine.
Turn
the upper lever as
sembly in as far as it
will
go and then back off one
full
turn
until the
hole
in the clutch lever aligns
with
hole
in the housing.
Assemble the lower clutch lever assembly in hous ing until faces of clutches contact then back off
not more than one-half
turn
which should bring
the aligning
hole
in the lever in line with the
hole
in
the housing. If the one-half
turn
does
not bring
the alignment
hole
in proper position, it
will
be
necessary to grind off (square with axis not to exceed .015") [0,397 mm.] the face of the lower
clutch;
in other words, backing off not more than
one-half
turn
from face to face contact
gives
the
proper
clearance of .015" to .031"
[0,397-0,794
mm.]
between
the two clutches.
Assemble the unit to the steering
post
in reverse
order
of dismantling and adjust remote control
rods.
After
assembly, if the shift dog catches on the
edge
of the slot in the clutch when moving the lever up
and
down, disconnect the shift rod at the
transmission
end and either lengthen or shorten it
slightly to correct this condition.

K-1. GENERAL
All
4-wheel-drive models are equipped with a
transfer
case to connect the power to the front
axle.
It is essentially a
two-speed
transmission
located at the
rear
of the standard transmission
and
provides a low and direct gear.
The
transfer case gears are controlled by the
driver
through
one shift lever.
Early
'Jeep'
Universal
Models with the F4-134
Hurricane
engine
are equipped with two transfer case shift control levers.
a.
On vehicles equipped with one transfer case
shift
lever, the transfer case shift lever has four
positions: 2WD
High,
4WD
High,
Neutral, and
4WD
low. The forward position of the lever 2WD
High
allows the
rear
wheels only to drive. The
first
rear
position (4WD High)
engages
the 4- wheel drive and provides high range 4-wheel drive.
The
second
rear
position (Neutral)
disengages
all power to the wheels and is used for stationary
power take-off operations. The last
rear
position
(4WD
Low) provides low range 4-wheel drive.
b.
On vehicles equipped with two transfer case
shift
levers, the transfer case front axle drive lever (left hand lever)
gives
a choice of 2-wheel or 4-
wheel drive. In the forward (out) position the
vehicle is in 2-wheel drive. Move the lever to the
rear
(in) position for 4-wheel drive operation.
The
4-wheel-drive
auxiliary-range
shift lever (right
hand
lever) has three positions; low, neutral, and
high.
The forward position (low)
gives
low-range
4-wheel drive. The center position (neutral) dis
engages
all power to the wheels and is used for
stationary
power take-off operations. A built-in in
terlock
prevents shifting into low range, 2-wheel
drive.
This
feature protects the
rear
axle from over
load.
K-2.
Removal of
Transfer
Case
The
transfer case may be removed from the vehicle
without removing the transmission. Where both
transmission
and transfer case are to be removed
together,
refer to Section J. To remove only the
transfer
case from the vehicle, proceed as follows:
a.
Drain
transmission
and transfer case and replace
drain
plugs.
b.
Disconnect the brake cable.
c.
Disconnect front and
rear
propeller shafts at
the transfer case. See "Propeller Shafts and
Uni
versal
Joints."
d.
Disconnect
speedometer
cable at transfer case. e. Disconnect the transfer case shift levers. On
vehicles equipped with two shift levers
loosen
set screw and remove pivot pin. Use a screw
driver
to pry shift lever springs away from shift levers.
Lift
levers from transfer case. On models equipped
with
a single shift lever remove pivot pin cotter
key,
and the adjusting rod attaching nut to remove
shift
lever. See Fig. K-4.
f. Remove cover plate on
rear
face of transfer case.
Remove
cotter key, nut and washer from trans
mission
main shaft.
g. If possible, at this point remove the transfer case main drive gear from the transmission main
shaft.
If not possible, see
step
j below.
h.
Remove transfer case torque reaction support
bracket
bolt and nut.
i.
Remove transmission to transfer case bolts.
j.
Remove transfer case. If the transfer case main
drive
gear has not been removed in
step
g above,
proceed as follows:
Brace
the end of the trans
mission
main shaft so that it cannot
move
in the
transmission,
pull
the transfer case to the
rear
