A140L Automatic Transaxle
CONSTRUCTION AND OPERATION
The A140L automatic transaxle can be roughly divided into the automatic transmission section and the
differential section. The automatic transmission section is composed of the torque converter, planetary
gear unit and the hydraulic control system.
OPERATION
The pump impeller is rotated by the engine, which
causes a flow in the ATF inside the torque converter.
The flow of ATF caused by the pump impeller strikes
the turbine runner, providing a force to rotate the tur-
bine runner, and transmits torque to the input shaft.
The flow of ATF which has hit the turbine runner re-
bounds and tries to flow in the direction opposite to
the direction of rotation of the pump impeller, but the
stator returns the flow the original direction of rotation.
So the ATF
becomes a force which supports the pump impeller
and increases torque.
HINT: Although the stator is immobilized by the one-
way clutch, should the one±way clutch become de-
fective the stator will be rotated by the flow of ATF,
the flow of
ATF will not be reversed, torque will not be increased
and the problem of inadequate acceleration will occur.
The lock±up clutch is pushed against the front cover
by fluid pressure so that the engine revolutions are
directly transmitted to the input shaft without the me-
dium of the
AT F.
1. Torque Converter
CONSTRUCTION
The torque converter is composed of the pump impeller
which is rotated by the engine, the turbine runner and
lock±up clutch which are fixed to the transmission input
shaft, and the stator which is attached to the stator
shaft via the one±way clutch.
The torque converter is filled with ATF.

HINT:
(1) In the 2 and L ranges, ail stages lock±up is OFF.
(2) In the following cases, the lock±up will be released regardless of the lock±up pattern.
When the throttle is completely closed.
When the brake light switch is ON.
*1 3 ± O/D up±shift point with closed throttle valve is at 32 ± 45 km/h (20 ± 28 mph).
*2 Lock±up ºONº' point with closed throttle valve is at 64 ± 73 km/h (40 ± 45 mph).
*3 Lock±up ºOFFº point with closed throttle valve is at 60 ± 68 km/h (37 ± 42 mph).

3. MEASURE BACKLASH OF SIDE GEAR
Measure each side gear backlash while holding one
pinion toward the case.
Standard backlash:
0.05 ± 0.20 mm (0.0020 ± 0.0079 in.)
4. REMOVE LH BEARING RETAINER
(a) Remove the six bolts.
(b) Tap the retainer with a plastic hammer to remove it
(c) Remove the O±ring from the retainer. 2. MEASURE TOTAL PRELOAD
Using a torque meter, measure the total preload, and
note the measurement value.

7. MEASURE DRIVE PINION PRELOAD
Using a torque meter, measure the drive pinion preload.
Preload (at starting):
Reused bearing 5 ± 8 kg±cm
(4.3 ± 6.9 in.±Ib, 0.5 ± 0.8 N±m)
The total preload measured in step 2 minus the drive pinion
preload equals 1.5 ± 2.0 kg±cm 0.3 ± 1.7 in.±Ib,
0.1 ±0.2N±m).
If the result is not within this specification, the side bearing
preload is bad.
8. REMOVE DRIVE PINION CAP6. REMOVE DIFFERENTIAL CASE, OUTER RACE AND
ADJUSTING SHIM
Remove the differential case, the outer race and the
adjusting shim from the case.
9. REMOVE COUNTER DRIVEN GEAR
(a) Using a chisel, loosen the staked part of the nut. 5. REMOVE RH SIDE BEARING CAP
Remove the two bolts and the side bearing cap.

3. CHECK SIDE GEAR BACKLASH
Using a dial gauge, measure the backlash of each side
gear while holding one pinion toward the case.
Standard backlash:
