AUTOMATIC TRANSAXLE ASSY
PRECAUTION
1. The automatic transaxle is composed of highly precision-finished parts, if nequine careful in-
spection before reassembly therefore even a small nick may cause fluid leakage or may de-
grade the performance. The instructions here are organized so that you work on only one com-
ponent group at a time. This will help you to avoid confusion about similar-looking parts of
different sub-assemblies being on your workbench at the same time. The component groups
are inspected and repaired from the converter housing side. Inspectio, repair and reassembly
As much as possible, before proceeding to the next component group. If a defect is found in
a certain component group during reassembly, inspect and repair this group immediately. If a
component group cannot be assembled because parts are being ordered, be sure to keep all
parts of the group in a separate container while proceeding with disassembly, inspection, re-
pair and reassembly of other component groups.
Recommended ATF: T-IV
2. All disassembled parts should be washed clean and any fluid passages and holes should be
blown with compressed air.
3. Dry all parts with compressed airnever use shop rags.
4. When using compressed air, do not aim at yourself to prevent accidentally spraying ATF or ker-
osene on your face.
5. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
6. After cleaning, the parts should be arranged in the correct order for efficient inspection, repairs,
and reassembly.
7. When disassembling a valve body, be sure to match each valve together with the correspond-
ing spring.
8. New discs for the brakes and clutches that are to be used for replacement must be soaked in
ATF for at least 15 minutes before reassembly.
9. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be
coated with ATF prior to reassembly.
10. All gaskets and rubber O-rings should be replaced.
11. Do not apply adhesive cements to gaskets and similar parts.
12. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed
in the groove correctly.
13. If a worn bushing is to be replaced, the sub-assembly containing the bushing must also be re-
placed.
14. Check thrust bearings and races for wear or damage. Replace if necessary.
15. Use petroleum jelly to keep parts in place.
16. When working with FIPG material, you must perform the following.
Using a razor blade and a gasket scraper, remove all the old packing (FIPG) material from the
gasket surface.
Thoroughly clean all components to remove all the loose material.
Clean both sealing surfaces with a non-residue solvent.
Parts must be reassembled within 10 minutes of application. Otherwise, the packing (FIPG) ma-
terial must be removed and reapplied.

REPAIR MANUAL SUPPLEMENT: VEHICLE PULLING TO ONE SIDE ± ST004-01 RevisedDecember 21, 2001
Page 6 of 11
1. IMPORTANT NOTICE
Before repairing vehicle pulling to one side, it is necessary to clearly identify the
cause of the pulling condition. Frequently, the cause of the vehicle pulling to one side
is diagnosed as wheel alignment. However, the actual cause may be lateral force
generated by the tires. Performing wheel alignment when tire force is the cause could
result in the wheel alignment being set at a value outside of specifications. This would
then cause other problems such as uneven tire wear, etc.
2. Troubleshooting
First determine whether vehicle pulling to one side is caused by a wheel alignment
problem or tire characteristics, then decide which repairs to make.
A. Perform the following checks and correct as necessary.
a. Check tires for size, wear and for proper inflation pressure.
b. Check whether the vehicle is noticeably tilted backward/forward or left/right.
NOTE:
Tilting of the vehicle produces a left±right difference in the camber and caster and can
cause vehicle pulling to one side.
c. Check brakes for dragging.
B. Confirm problem symptoms.
With the customer accompanying you, drive the vehicle to confirm if the
customer 's complaint involves vehicle pulling to one side or steering wheel off
center. If the problem is steering wheel off center, adjust the front tie rods on the
vehicle. Refer to Lexus TSIB ST002±01. Also check the direction of vehicle
pulling and the extent of the pulling.
C. Decide if vehicle pulling is due to wheel alignment or tires.
a. Switch the left and right front tires (If the tires are non±unidirectional).
b. Conduct a drive test to check whether the direction that the vehicle pulls has
changed.
