Leaks at the rear of the extension or adapter hous-
ing will be from the housing oil seals. Leaks at com-
ponent mating surfaces will probably be the result of
inadequate sealer, gaps in the sealer, incorrect bolt
tightening, or use of a non–recommended sealer.
A leak at the front of the transmission will be from
either the front bearing retainer or retainer seal.
Lubricant may be seen dripping from the clutch
housing after extended operation. If the leak is
severe, it may also contaminate the clutch disc caus-
ing the disc to slip, grab, and/or chatter.
A correct lubricant level check can only be made
when the vehicle is level. Also allow the lubricant to
settle for a minute or so before checking. These rec-
ommendations will ensure an accurate check and
avoid an underfill or overfill condition. Always check
the lubricant level after any addition of fluid to avoid
an incorrect lubricant level condition.
HARD SHIFTING
Hard shifting is usually caused by a low lubricant
level, improper, or contaminated lubricants. The con-
sequence of using non–recommended lubricants is
noise, excessive wear, internal bind, and hard shift-
ing. Substantial lubricant leaks can result in gear,
shift rail, synchro, and bearing damage. If a leak
goes undetected for an extended period, the first indi-
cations of component damage are usually hard shift-
ing and noise.
Shift component damage, incorrect clutch adjust-
ment, or a damaged clutch pressure plate or disc are
additional probable causes of increased shift effort.
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 rebuilt 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 generally only at extreme
speeds.
Severe, highly audible transmission noise is gener-
ally the initial indicator 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 leads to gear and bearing
damage.
REMOVAL
(1) Shift transmission into neutral.
(2) Raise and support the vehicle.
(3) Support engine with jack stand. Position wood
block between jack and oil pan to avoid damaging
pan.
(4) Remove skid plate/crossmember.
(5) Support transmission with a trans jack.
(6) Remove transmission mount from transmission
and exhaust.
(7) Remove propeller shafts.
(8) Remove transfer case shift linkage and vent
hose.
(9) Remove wiring connectors from transmission
and transfer case.
(10) Remove transfer case.
(11) Remove slave cylinder from clutch housing.
(12) Remove starter.
(13) Remove transmission dust shield.
(14) Lower trans jack enough to remove shift
tower bolts.
(15) Lower transmission jack and remove trans-
mission from under vehicle.
(16) Pull transmission jack rearward (Fig. 1) until
input shaft clears clutch.
