1. Clutch System
Condition Possible cause and testing Corrective action
1. Clutch slip-
pageIt is hard to perceive clutch slippage in the early stage, but pay attention to the following symptoms.
(a) Engine revs up when shifting.
(b) High speed driving is impossible; especially rapid acceleration impossible and vehicle speed does not increase in
proportion to an increase in engine speed.
(c) Power falls, particularly when ascending a slope, and there is a smell of burning of the clutch facing.
Method of testing: Put the vehicle in stationary condition with parking brake fully applied. Disengage the clutch and
shift the transmission gear into the first. Gradually allow the clutch to engage while gradually increasing the engine
speed. The clutch function is satisfactory if the engine stalls. However, the clutch is slipping if the vehicle does not
start off and the engine does not stall.
(a) No clutch pedal play Readjust.
(b) No release lever end play Readjust.
(c) Clutch facing smeared by oil Replace.
(d) Worn clutch facing Replace.
(e) Deteriorated diaphragm spring Replace.
(f ) Distorted pressure plate or flywheel Correct or replace.
(g) Defective release bearing holder Correct or replace.
(h) Defective pedal and cable system Correct or replace.
2. Clutch
drags.As a symptom of this trouble, a harsh scratching noise develops and control becomes quite difficult when shifting
gears. The symptom becomes more apparent when shifting into the first gear. However, because much trouble of the
this sort is due to defective synchronization mechanism, carry out the test as described after.
Method of testing: Refer to DIAGNOSTIC DIAGRAM on page after.
It may be judged as insufficient disengagement of clutch if any noise occurs during this test.
(a) Excessive clutch pedal play Readjust.
(b) Excessive clutch release lever play Readjust.
(c) Worn or rusty clutch disc hub spline Replace clutch disc.
(d) Excessive deflection of clutch disc facing Correct or replace.
(e) Seized crankshaft pilot needle bearing Replace.
(f ) Malfunction of pedal and cable system Correct or replace.
(g) Cracked clutch disc facing Replace.
(h) Sticked clutch disc (smeared by oil or water) Replace.
3. Clutch chat-
ters.Clutch chattering is an unpleasant vibration to the whole body when the vehicle is just started with clutch partially
engaged.
(a) Improper clutch cable routing Correct.
(b) Adhesion of oil on the facing Replace clutch disc.
(c) Weak or broken torsion spring Replace clutch disc.
(d) Defective facing contact or excessive disc Replace clutch disc defection.
(e) Warped pressure plate or flywheel Correct or replace.
(f ) Loose disc rivets Replace clutch disc.
(g) Loose engine mounting Retighten or replace mounting.
(h) Improper adjustment of pitching stopper Adjustment.

3. Performance Test
A: STALL TEST
1. GENERAL
The stall test is of extreme importance in diagnosing the
condition of the automatic transmission and the engine. It
should be conducted to measure the engine stall speeds in
all shift ranges except the P and N ranges.
Purposes of the stall test:
1) To check the operation of the automatic transmission
clutch.
2) To check the operation of the torque converter clutch.
3) To check engine performance.
2. TEST METHODS
Preparations before test:

1Check that throttle valve opens fully.

2Check that engine oil level is correct.

3Check that coolant level is correct.

4Check that ATF level is correct.

5Check that differential gear oil level is correct.

6Increase ATF temperature to 50 to 80°C (122 to 176°F)
by idling the engine for approximately 30 minutes (with
select lever set to“N”or“P”).
1) Install an engine tachometer at a location visible from
the driver’s compartment and mark the stall speed range
on the tachometer scale.
2) Place the wheel chocks at the front and rear of all
wheels and engage the parking brake.
3) Move the manual linkage to ensure it operates properly,
and shift the select lever to the 2 range.
B3M0286B
4) While forcibly depressing the foot brake pedal, gradu-
ally depress the accelerator pedal until the engine operates
at full throttle.
5) When the engine speed is stabilized, read that speed
quickly and release the accelerator pedal.
6) Shift the select lever to Neutral, and cool down the
engine by idling it for more than one minute.
7) Record the stall speed.
8) If stall speed in 2 range is higher than specifications,
forward clutch slipping on brake band slipping may occur.
To identify it, conduct the same test as above in D range.
9) Perform the stall tests with the select lever in the R
range.
CAUTION:
Do not continue the stall test for MORE THAN FIVE
SECONDS at a time (from closed throttle, fully open
throttle to stall speed reading). Failure to follow this
instruction causes the engine oil and ATF to deterio-
rate and the clutch and brake band to be adversely
affected.
