INTRODUCTION
TOYOTA
A130 TRANSAXLE
The A 130 Transaxle is a front wheel drive fully automatic
transmission with a convener clutch . Trouble-shooting,
teardown-assembly, removal and ins.tallation is fully cov-
ered.

This transmission is currently found in the Toyota Corolla

models.

GENERAL NOTES
1. Trou bles occuring with the automatic transm ission can be caused by either the engine or the transmis-
sion itself. These two areas should be distinctly isolated before proceeding with troubleshooting.

2. Troubleshooting should begin with the simpliest operation, working up in order o f difficulty, but first
determine whether the trouble lies within the engine or transmission.

3. Proceed with the inspection as follows.

( 1) Preminary Check
Basic check
(a) Check o il level.
(b) Check throttle cable mark.
(cl Check shift cable.
(d) Check neutral start switch.
(e) Check idle speed.
(f) Check tire inflation pressure (See page
FA·3). Repair as necessary.

Chtck engine and torque convener. (2) Stall Test

Repair as necessary.
Ch eck A TM (3) Time Lag Test
Check each clutch. brake and gear for wear.
Confirm by road test and repair as necessary.

Measure line pressure and make basic check of (4) Hydraulic Test
flu id circuit . Confirm shift point and extent c>f shock by
road test. Repair as necessary,

Check A TM by r oad test.

(5) Road Test
Confirm if trouble lies within ATM.
If noisy o r vibrating, the possible cause could
Overhaul transm ission be with the compressor, engine, drive shaft,
tires, etc.

NOTE: The preload will change about 3 - 4 kg-cm (2.6

- 3.5 in.·lb, 0.3 - 0.4 N·m) with each shim thickness.
7. REMOVE DIFFERENT IAL CASE AND COMPON ENT
PARTS
If the pre load ·is adjusted within specification, remove the
bearing retainer, differential case, RH side bearing and
shi m.
Be careful not to lose the adjusted shim.

PINION SHAFT
1. INSTAL L NEW O·RING ONTO BEAR ING CAGE

2. PLACE BEARING CAGE ONTO DRIVE PI NI ON SHAFT

Be careful not to damage the oil seal with the splines.

3. INSTAL L GOV ERNOR DRIV E GEAR

4. INSTALL DRIVE PINION SHA FT INTO CASE

Slightly tap the cage into the case until the groove with
the bore can be seen.
NOTE: Drive in the bearing cage until the surface o f the
bearing cage passes th rough the groove with the bore.

5. INSTA LL SNAP RING INTO CASE

(a) Using SST, install the snap ring into the groove.
SST 09350-32011

(b) Slightly tap the drive pinion to fit the snap ring
into the groove.

6. INSTALL OIL SLINGER
Install the oil slinger, facing the lip outward.

7. INSTALL OUTER RACE

Using SST, d rive the outer race into the case.
SST 09350-3201 1

8. INSTALL NEW SPACER

Always use a new spacer.
Install the spacer with the small end first.

9. INSTALL COUNTER DRIVEN GEAR ONTO SHAFT

(a) Place a ·bar at the drive pinion side and position the
other end of the bar against a vise or such.
(b) Drive the gear onto the shaft until the nut can be
installed on t he threads of the shaft.
CAUTION: Be careful not to cause a shock to the trans·
mission case.

10. ADJUST DR IVE !PIN ION PRELOAD

(a) Coat the threads and surface of the nut with MP
grease.
(b) Using SST to hold the gear, tighten the nut.
Torque: 1,750 kg-cm (127 ft·lb, 172 N·m)

{c) T urn th e gear counterclockwise and clockwise several

times.
{d) Using a, torque meter, measu re the preload of the
drive pinion.
Preload (at starting):
New bear ing 10 - 16 kg•cm
(8.7 - 13.9 in.-lb. 1.0 - 1.6 N·m)
Reused bearing 5 - 8 kg-cm
(4.3 - 6.9 in.-lb, 0.5 - 0.8 N·m)
• If the preload is greater than specified, replace the
bearing spacer.
• r f the preload is less than specified, retighten the
nut 130 kg•cm (9 ft•lb, 13 N·m) at a time until the
specified preload is reached.
ff t he maximum torque is exceeded whi le retightening the
nut, replace the bearing spacer and repeat the prefoad pro-
cedure.
Do not back off the nut to reduce the preload.
Maximum torq ue: 2,950 kg-cm (213 ft-lb, 289 N·m)
{e) If the preload is adjusted within specification, make a
note of i t.
