ON±VEHICLE INSPECTION
1. CHECK THE FLUID LEVEL
HINT:
Drive the vehicle so that the engine and transaxle are at the nor-
mal operating temperature.
Fluid temperature: 70 ± 80
C (158 ± 176
F)
(a) Park the vehicle on a level surface and set the parking
brake.
(b) With the engine idling and the brake pedal depressed,
shift the shift lever into all position from P to L position and
return to P position.
(c) Pull out the dipstick and wipe it clean.
(d) Push it back fully into the pipe.
(e) Pull it out and check that the fluid level is in the HOT posi-
tion.
If there are leaks, it is necessary to repair or replace O±rings,
FIPGs, oil seals, plugs or other parts.

PRECAUTION
1. The automatic transaxle is composed of highly precision±finished parts which need careful in-
spection before reassembly because even a small nick could cause fluid leakage or affect the
performance. The instructions here are organized in order to work on only one component
group at a time. This will help avoid confusion comes from the similar±looking part of the differ-
ent sub±assemblies being on your workbench at the same time. Inspect and repair the compo-
nent groups from the converter housing side. Complete the inspection, repair and reassembly
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 can-
not be assembled because the necessary parts are being ordered, be sure to keep all the parts
of the group in a separate container while proceeding with disassembly, inspection, repair and
reassembly of the other component groups.
Recommended ATF: T±IV
2. All the disassembled parts should be washed clean and any fluid passages and holes should
be blown through with compressed air.
3. Dry all parts with compressed air. Never use shop rags to dry them.
4. Be careful of ATF or kerosene not to be squirted over your face when using compressed air.
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 the valve body, be sure to match each valve together with the correspond-
ing spring.
8. New discs for the replacement of the brakes and clutches must be soaked in ATF for at least
15 minutes before reassembly.
9. All the oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be
coated with ATF prior to reassembly.
10. Replace all the gaskets and rubber O±rings.
11. Do not apply adhesive cements to the gaskets and similar parts.
12. Make sure that the ends of the 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 the thrust bearings and races for wear or damage. Replace them as necessary.
15. Use petroleum jelly to keep the parts in place.
16. When working with FIPG material, you must follow the procedure below.

Remove all the old packing (FIPG) material from the gasket surface using a razor blade and a
gasket scraper.

Thoroughly clean all the components to remove all the loose material.

Clean both the sealing surfaces with non±residue solvent.

Parts must be reassembled within 10 minutes of application. Otherwise, the packing (FIPG) ma-
terial must be removed and reapplied.
