1. Manual Transmission and
Differential
Symptom and possible cause Remedy
1. Gears are difficult to intermesh.
The cause for difficulty in shifting gears can be classified into two kinds: one is malfunction of the gear shift system and the
other is malfunction of the transmission. However, if the operation is heavy and engagement of the gears is difficult, defective
clutch disengagement may also be responsible. Check whether the clutch is correctly functioning, before checking the gear
shift system and transmission.
(a) Worn, damaged or burred chamfer of internal spline of
sleeve and reverse driven gearReplace.
(b) Worn, damaged or burred chamfer of spline of gears Replace.
(c) Worn or scratched bushings Replace.
(d) Incorrect contact between synchronizer ring and gear
cone or wearCorrect or replace.
2. Gear slips out.
(1) Gear slips out when coasting on rough road.
(2) Gear slips out during acceleration.
(a) Defective pitching stopper adjustment Adjust.
(b) Loose engine mounting bolts Tighten or replace.
(c) Worn fork shifter, broken shifter fork rail spring Replace.
(d) Worn or damaged ball bearing Replace.
(e) Excessive clearance between splines of synchronizer hub
and synchronizer sleeveReplace.
(f) Worn tooth step of synchronizer hub (responsible for slip-
out of 3rd gear)Replace.
(g) Worn 1st driven gear, needle bearing and race Replace.
(h) Worn 2nd driven gear, needle bearing and race Replace.
(i) Worn 3rd drive gear and bushing Replace.
(j) Worn 4th drive gear and bushing Replace.
(k) Worn reverse idler gear and bushing Replace.
3. Unusual noise comes from transmission.
If an unusual noise is heard when the vehicle is parked with its engine idling and if the noise ceases when the clutch is
disengaged, it may be considered that the noise comes from the transmission.
(a) Insufficient or improper lubrication Lubricate or replace with specified oil.
(b) Worn or damaged gears and bearings Replace.
NOTE: If the trouble is only wear of the tooth surfaces, merely
a high roaring noise will occur at high speeds, but if any part
is broken, rhythmical knocking sound will be heard even at
low speeds.

1. Manual Transmission and Differential

Symptom and possible cause Remedy
4. Broken differential (case, gear, bearing, etc.)
Abnormal noise will develop and finally it will become impossible to continue to run due to broken pieces obstructing the gear
revolution.
(a) Insufficient or improper oil Disassemble differential and replace broken components and
at the same time check other components for any trouble,
and replace if necessary.
(b) Use of vehicle under severe conditions such as excessive
load and improper use of clutchReadjust bearing preload and backlash and face contact of
gears.
(c) Improper adjustment of taper roller bearing Adjust.
(d) Improper adjustment of drive pinion and hypoid driven
gearAdjust.
(e) Excessive backlash due to worn differential side gear,
washer or differential pinionAdd recommended oil to specified level. Do not use vehicle
under severe operating conditions.
(f) Loose hypoid driven gear clamping bolts Tighten.
5. Differential and hypoid gear noises
Troubles of the differential and hypoid gear always appear as noise problems. Therefore noise is the first indication of the
trouble. However noises from the engine, muffler, tire, exhaust gas, bearing, body, etc. are easily mistaken for the differential
noise. Pay special attention to the hypoid gear noise because it is easily confused with other gear noises. There are the
following four kinds of noises.
(1) Gear noise when driving: If noise increases as vehicle speed increases it may be due to insufficient gear oil, incorrect
gear engagement, damaged gears, etc.
(2) Gear noise when coasting: Damaged gears due to maladjusted bearings and incorrect shim adjustment
(3) Bearing noise when driving or when coasting: Cracked, broken or damaged bearings
(4) Noise which mainly occurs when turning: Unusual noise from differential side gear, differential pinion, differential pinion
shaft, etc.
(a) Insufficient oil Lubricate.
(b) Improper adjustment of hypoid driven gear and drive
pinionCheck tooth contact.
(c) Worn teeth of hypoid driven gear and drive pinion Replace as a set.
Readjust bearing preload.
(d) Loose roller bearing Readjust hypoid driven gear to drive pinion backlash and
check tooth contact.
(e) Distorted hypoid driven gear or differential case Replace.
(f) Worn washer and differential pinion shaft Replace.

1. Precaution
When disassembling or assembling the automatic
transmission, observe the following instructions.
1) Workshop
Provide a place that is clean and free from dust. Principally
the conventional workshop is suitable except for a dusty
place. In a workshop where grinding work, etc. which pro-
duces fine particles is done, make independent place
divided by the vinyl curtain or the equivalent.
2) Work table
The size of 1 x 1.5 m (40 x 60 in) is large enough to work,
and it is more desirable that its surface be covered with flat
plate like iron plate which is not rusted too much.
3) Cleaning of exterior
(1) Clean the exterior surface of transmission with
steam and/or kerosene prior to disassembly, however it
should be noted that vinyl tape be placed on the air
breather or oil level gauge to prevent infiltration of the
steam into the transmission and also the cleaning job
be done away from the place of disassembly and
assembly.
(2) Partial cleaning will do, depending on the extent of
disassembly (such as when disassembly is limited to
some certain parts).
4) Disassembly, assembly and cleaning
(1) Disassemble and assemble the transmission while
inspecting the parts in accordance with the Diagnostics.
(2) During job, don’t use gloves. Don’t clean the parts
with rags: Use chamois or nylon cloth.
(3) Pay special attention to the air to be used for clean-
ing. Get the moisture and the dust rid of the air as much
as possible. Be careful not to scratch or dent any part
while checking for proper operation with an air gun.
(4) Complete the job from cleaning to completion of
assembly as continuously and speedily as possible in
order to avoid occurrence of secondary troubles
caused by dust. When stopping the job unavoidably
cover the parts with clean chamois or nylon cloth to
keep them away from any dust.
(5) Use kerosene, white gasoline or the equivalent as
washing fluid. Use always new fluid for cleaning the
automatic transmission parts and never reuse. The
used fluid is usable in disassemble and assemble work
of engine and manual transmission.
(6) Although the cleaning should be done by dipping
into the washing fluid or blowing of the pressurized
washing fluid, the dipping is more desirable. (Do not rub
with a brush.) Assemble the parts immediately after the
cleaning without exposure to the air for a while. Besides
in case of washing rubber parts, perform the job quickly
not to dip them into the washing fluid for long time.

A: INSPECTION
1. ATF LEVEL
1) Raise ATF temperature to 60 to 80°C (140 to 176°F)
from 40 to 60°C (104 to 140°F) (when cold) by driving a
distance of 5 to 10 km (3 to 6 miles).
NOTE:
The level of ATF varies with fluid temperature. Pay atten-
tion to the fluid temperature when checking oil level.
2) Make sure the vehicle is level. After selecting all posi-
tions (P, R, N, D, 3, 2, 1), set the selector leveler in“P”
range. Measure fluid level with the engine idling.
NOTE:
After running, idle the engine for one or two minutes before
measurement.
3) If the fluid level is below the center between upper and
lower marks, add the recommended ATF until the fluid level
is found within the specified range (above the center
between upper and lower marks). When the transmission
is hot, the level should be above the center of upper and
lower marks, and when it is cold, the level should be found
below the center of these two marks.
CAUTION:
Use care not to exceed the upper limit level.
ATF level varies with temperature. Remember that
the addition of fluid to the upper limit mark when the
transmission is cold will result in the overfilling of
fluid.
4) Fluid temperature rising speed
By idling the engine
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 25 minutes

Time for temperature rise to 30°C (86°F) with atmo-
spheric temperature of 0°C (32°F): Approx. 8 minutes
By running the vehicle
Time for temperature rise to 60°C (140°F) with atmo-
spheric temperature of 0°C (32°F): More than 10 minutes
5) Method for checking fluid level upon delivery or at peri-
odic inspection
Check fluid level after a warm-up run of approx. 10 min-
utes. During the warm-up period, the automatic transmis-
sion functions can also be checked.

2. DIFFERENTIAL GEAR OIL LEVEL
1) Ensure the vehicle is in safe condition.
NOTE:
Do not check the oil level nor add oil to the case with the
front end of the vehicle jacked-up; this will result in an
incorrect reading of the oil level.
2) Check whether the oil level is between the upper (F)
and lower (L) marks. If it is below the lower limit mark, add
oil until the level reaches the upper mark.

3. OIL LEAKAGE
It is difficult to accurately determine the precise position of
a oil leak, since the surrounding area also becomes wet
with oil. The places where oil seals and gaskets are used
are as follows:
Jointing portion of the case
Transmission case and oil pump housing jointing portion
Torque converter clutch case and oil pump housing joint-
ing portion
Transmission case and transmission cover jointing por-
tion (FWD)
