SYSTEM DESCRIPTION
1. SYSTEM DESCRIPTION
(a) The ECT (Electronic controlled automatic transmission/transaxle) is an automatic transmission/trans-
axle that electronically controls shift timing using the ECM. The ECM detects electrical signals that indi-
cate engine and driving conditions, controls the shift point, and selects the appropriate shift pattern
based on driver habits and road conditions. As a result, fuel efficiency and power transmission/trans-
axle performance are improved.
Shift shock has been reduced by controlling the engine and transmission/transaxle simultaneously.
In addition, the ECT has the following features:
SDiagnostic function.
SFail−safe function when a malfunction occurs.

PRECAUTION
1. MAINTENANCE PRECAUTION
(a) Do not stop the engine immediately after pulling a trailer,
or after high speed or uphill driving. Let the engine idle for
20 to 120 seconds before turning the ignition switch to
OFF (according as the driving condition, the idling time
varies).
(b) Avoid quickly accelerating the pedal or increasing the en-
gine speed immediately after starting a cold engine.
(c) If the turbocharger is found defective, it must be replaced.
Also, inspect the source of the trouble including condi-
tions of the turbocharger that having been used. Repair
or replace the followings if necessary:
(1) Engine oil (level and quality)
(2) Oil lines leading to the turbocharger
(d) Pay due attention when removing and reinstalling the
turbocharger assembly. Do not drop, grasp, or give shock
to the easily−deformed assembly parts such as the actua-
tor or push rod when removing or reinstalling.
(e) Before removing, cover both the intake and exhaust ports
and the oil inlet to prevent dirt or foreign objects from be-
ing introduced.
(f) If replacing the turbocharger, check the oil pipe for depos-
its. If necessary, replace the oil pipe, too.
(g) Thoroughly remove old gasket sticking to the lubrication
oil pipe flange and turbocharger oil flange.
(h) If replacing the bolt(s) or nut(s), Toyota genuine parts
must be used to prevent breakage or deformation.
(i) If replacing the turbocharger, put 20 cm
3(1.2 cu in.) of
fresh oil into the turbocharger oil inlet hole, then turn the
turbine wheel by hand to spread oil to the bearing.
(j) If overhauling or replacing the engine, cut the fuel supply
after reassembling and crank the engine for 30 seconds
to feed oil throughout the engine. Run the engine at idle
for 60 seconds.

(b) While applying the brake, remove the axle hub LH nut.
NOTICE:
Loosen the staked part of the lock nut completely, other-
wise the screw of the drive shaft may become damaged.
5. SEPARATE FRONT STABILIZER LINK ASSY LH
(a) Remove the nut and separate the front stabilizer link assy
LH from the shock absorber assy LH.

wrench (6 mm) to hold the stud.
6. DISCONNECT SPEED SENSOR FRONT LH
(a) Remove the bolt, and disconnect the speed sensor wire
and flexible hose from the shock absorber.
(b) Remove the bolt, and disconnect the speed sensor from
the steering knuckle.
NOTICE:
SBe careful not to damage the speed sensor.
SPrevent foreign matter from adhering to the speed
sensor.

(b) Measure the time lag.
(1) When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag
before the shock can be felt. This is used for checking the condition of the direct clutch, forward
clutch, and 1st and reverse brake.
NOTICE:

Perform the test at the normal operating ATF temperature 50 to 80
C (122 to 176
F).

Be sure to allow 1 minute interval between tests.

Perform the test three times, and measure the time lags. Calculate the average value of the three
time lags.
(2) Connect an Intelligent Tester II to the DLC3.
(3) Fully apply the parking brake.
(4) Start and warm up the engine and check idle speed.
Idle speed: approx. 700 rpm (In N position and A/C OFF)
(5) Shift the lever from N to D position. Using a stop watch, measure the time from when the lever
is shifted until the shock is felt.
Time lag: N → D less than 1.2 seconds
(6) In the same way, measure the time lag for N → R.
Time lag: N → R less than 1.5 seconds
Evaluation (If N → D or N → R time lag is longer than the specified):
ProblemPossible cause
N → D time lag is longer

Line pressure is too low

Forward clutch worn

One–way clutch No.2 not operating properly
N → R time lag is longer

Line pressure is too low

Reverse clutch worn

1st and reverse brake worn
