PRECAUTION
1. The automatic transmission is composed of highly precision-finished parts which need careful inspection
before reassembly because even a small nick could cause fluid leakage or affect performance. The
instructions here are organized so that you work on only one component group at a time. This will help
avoid confusion from similar-looking parts of different sub-assemblies being on your workbench at the
same time. The component groups should be inspected and repaired from the converter housing side.
Inspect, repair and reassemble 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, repair and
reassembly of other component groups. Recommended ATF: ATF WS
2. All 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.
4. When using compressed air, be careful not to not aim at yourself to prevent accidentally spraying ATF or
kerosene on your face.
5. Only 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 corresponding 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 or 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. When replacing a worn bushing, the sub-assembly containing the bushing must also be replaced.
14. Check thrust bearings and races for wear or damage. Replace them as necessary.
15. Use petroleum jelly to keep parts in place.
16. When working with FIPG material, 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 any loose material.

HINT:
If you cannot add the listed amount of fluid, do the following:
1. Install the refill plug.
2. Allow the engine to idle with air conditioning OFF.
3. Move the shift lever through entire gear range to circulate fluid.
4. Wait for 30 seconds with the engine idling.
5. Stop the engine.
6. Remove the refill plug and add fluid.
7. Reinstall the refill plug.
4.FLUID CIRCULATION

2. Select the tester menus: OBD/MOBD, ENGINE, DATA LIST and A/T.
3. Check A/T OIL TEMP.
4. Allow the engine to idle until the fluid temperature reaches 46°C (115°F).
b. Without hand-held tester (Using D shift indicator)
1. Create a short circuit between CG (4) and TC (13) of the DLC3 terminals using SST (09843-
18040).
2. Move the shift lever back and forth between N and D at 1.5 seconds interval for six seconds.
3. The D shift indicator on the combination meter comes on for two seconds when the
combination meter begins to detect the fluid temperature.
4. The D shift indicator comes on again when the fluid temperature reaches 46°C (115°F) and
blinks when it exceeds 56°C (130°F).
c. For vehicles with air suspension (Using D shift indicator)
1. Create a short circuit between CG (4), OPA (11) and TC (13) of the DLC3 terminals using
SST (09843-18040).
2. Move the shift lever back and forth between N and D at 1.5 seconds interval for six seconds.
3. The D shift indicator on the combination meter comes on for two seconds when the
combination meter begins to detect the fluid temperature.

psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found,
check the heater core, cylinder block and head.
2.CHECK ENGINE COOLANT LEVEL AT RESERVOIR
a. Check that the engine coolant level is between the LOW and FULL lines when the engine is cold.
If the engine coolant is low, check for leaks and add "TOYOTA Super Long Life Coolant" to the
FULL line.
If "TOYOTA Super Long Life Coolant" is not available, use a similar high quality ethylene glycol
based non-silicate, non-amino, non-nitrite and non-borate coolant with long-life hybrid organic acid
technology. Do not substitute plain water for engine coolant.
3.CHECK ENGINE COOLANT QUALITY
a. Remove the radiator cap.
b. Check if there are any excessive deposits of rust or scale around the radiator cap and radiator filler
hole, Also, the coolant should be free from oil.
HINT:
If excessively dirty, clean the coolant passage and replace the coolant.
c. Reinstall the radiator cap.
