(4) Tighten fittings at pump and gear to 28 Nzm
(21 ft. lbs.) torque.
(5) After installation, add power steering fluid, in-
spect and test for fluid leaks.
PUMP REPLACEMENT
REMOVAL
(1) Remove and cap pressure and return lines from
pump. Refer to Pressure and Return Line Replace-
ment in this section.(2) Remove belt tension, turn tensioner clock-wise
and slip belt off pulley (Fig. 6).
(3) Remove the screws retaining front bracket and
pump to the rear bracket (Fig. 7, 8).
(4) Remove screws that attach the front bracket to
the rear bracket (Fig. 9).
(5) Remove pump from bracket.
To remove the rear bracket from engine, the air
conditioning compressor and bracket must be re-
moved first. Refer to Group 24, Heating and Air Con-
ditioning for removal procedures.
(6) Remove fan from pulley and hub on rear

INSTALLATION
(1) Install the rear bracket to engine. Install
screws finger tight.
(2) Tighten front screws to 48 Nzm (35 ft. lbs.)
torque. Tighten side screw to 48 Nzm (35 ft. lbs.)
torque. It is important to torque the front screws
FIRST and the side screw LAST. This will prevent
the bracket from twisting or distorting.
(3) Install fan to pulley and hub. Tighten the nuts
to 27 Nzm (20 ft. lbs.) torque.
(4) Install air conditioning bracket and compressor
to engine. Refer to Group 24, Heating and Air Condi-
tioning for installation procedures.(5) Loose assemble screws through front bracket,
pump and into rear bracket.
(6) Install screws that attach the front bracket to
the rear bracket (Fig. 8). Tighten the screws to 27
Nzm (20 ft. lbs.) torque (Fig. 7).
(7) Install belt, turn tensioner clockwise and slip
belt onto pulley (Fig. 6).
(8) Install pressure and return lines to pump. Re-
fer to Pressure and Return Line Replacement in this
section.
(9) After installation, add power steering fluid, in-
spect and test for fluid leaks. Refer to Power Steering
PumpÐInitial Operation.

happens when the container delivery mechanism is im-
properly calibrated. Always check the lubricant level af-
ter filling to avoid an under fill condition.
A correct lubricant level check can only be made
when the vehicle is level; use a drive-on hoist to en-
sure this. Also allow the lubricant to settle for a
minute or so before checking. These recommenda-
tions will ensure an accurate check and avoid an un-
der-or-overfill condition.
HARD SHIFTING
Hard shifting is usually caused by a low lubricant
level, improper or contaminated lubricants, compo-
nent damage, incorrect clutch adjustment, or by a
damaged clutch pressure plate or disc.
Substantial lubricant leaks can result in gear, shift
rail, synchro and bearing damage. If a leak goes un-
detected for an extended period, the first indications
of a problem are usually hard shifting and noise.
Incorrect or contaminated lubricants can also con-
tribute to hard shifting. The consequence of using
non-recommended lubricants is noise, excessive wear,
internal bind and hard shifting.
Improper clutch release is a frequent cause of hard
shifting. Incorrect adjustment or a worn, damaged
pressure plate or disc can cause incorrect release. If
the clutch problem is advanced, gear clash during
shifts can result.
Worn or damaged synchro rings can cause gear clash
when shifting into any forward gear. In some new or re-
built transmissions, new synchro rings may tend to
stick slightly causing hard or noisy shifts. In most
cases, this condition will decline as the rings wear-in.
TRANSMISSION NOISE
Most manual transmissions make some noise dur-
ing normal operation. Rotating gears generate a mild
whine that is audible but only at extreme speeds.
Severe, highly audible transmission noise is gener-
ally the result of a lubricant problem. Insufficient,
improper, or contaminated lubricant will promote
rapid wear of gears, synchros, shift rails, forks and
bearings. The overheating caused by a lubricant
problem, can also lead to gear breakage.
TRANSMISSION REMOVAL
(1) Shift transmission into first or third gear. Then
raise vehicle on hoist.
(2) Support engine with adjustable jack stand. Po-
sition wood block between jack and oil pan to avoid
damaging pan.
(3) Disconnect necessary exhaust system components.
(4) Remove skid plate.
(5) Disconnect rear cushion and bracket from
transmission (Fig. 5).

unseat shift lever dust boot from transmission shift
tower (Fig. 6). Move boot upward on shift lever for
access to retainer that secures lever in shift tower.
(c) Reach up and around transmission case and
press shift lever retainer downward with your fin-
gers. Turn retainer counterclockwise to release it.
(d) Lift lever and retainer out of shift tower (Fig.
6).Do not remove the shift lever from the
floorpan boots. Leave the lever in place for
later transmission installation.
(11) Mark front and rear propeller shafts for in-
stallation alignment (Fig. 7). Then remove both
shafts.
(12) Remove crankshaft position position sensor
(Figs. 8, 9).
CAUTION: It is important that the crankshaft posi-
tion sensor be removed prior to transmission re-
moval. The sensor can easily be damaged if left in
place during removal operations.
(13) Unclip wire harnesses from transmission and
transfer case.
(14) Remove slave cylinder from clutch housing.
(15) Support transmission with transmission jack.
(16) Remove nuts attaching transfer case to trans-
mission and remove transfer case.
(17) Secure transmission to jack with safety
chains.
(18) Remove clutch housing brace rod.(19) Remove clutch housing-to-engine bolts.
