WS ATF Level Adjustment for U660E/F Transmissions

Inspection Procedure

1. Inspect fluid level at vehicle operating temperature.
NOTE
This procedure references a Lexus vehicle equipped with a U660F transaxle as an example.
Refer to the Repair Manual of the corresponding vehicle model for specific details about
procedures that vary by model such as fluid type, oil level, filling method, the location of
the refill plug and overflow plug, torque, etc.

CAUTION

• Use caution while the engine is idling and the radiator fan is operating.
• Use caution when the transmission fluid temperature is high.

2. Warm up and stop the engine.
3. Connect Techstream to the DLC3 with the ignition switch OFF.
4. Turn the ignition switch to ON and turn Techstream ON .
NOTE
To reduce load, make sure that all electrical systems, such as the air conditioning, lighting
system, electric fan, and audio system are OFF.

5. On Techstream , enter the following menus:
Powertrain I ECT I Data List

6. Select the Data List menu : "A/T Oil Temperature 1"
7. Select the Data List menu : "Engine Speed"
8. Check the ATF temperature.
NOTE
Ensure the transmission fluid temperature is between 185°F - 194° F (85° C - 90°C) before
starting work.

9. Depress and hold the brake pedal.
10. Start the engine.
11. Slowly move the shift lever from P to D, and then back to P

Inspection Procedure (Continued)
NOTE
Ensure both of the Fluid Extraction Tank valves are OFF by turning the valve handle
perpendicular to the hose.

18. Connect a shop air hose to the Fluid Extraction Tank.
CAUTION
Do NOT exceed 100 psi of shop air pressure to the Fluid Extraction Tank.

19. Open the Fluid Extraction Tank LOWER valve by turning the handle in-line with the hose.
20. Open the Fluid Extraction Tank UPPER valve by turning the handle in-line with the hose.
HINT
Vacuum will be applied to the transmission when both of the Fluid Extraction Tank valves are
opened to prevent fluid loss when removing/installing the transmission overflow/drain plug.

NOTE
Ensure the Vacuum Regulator Manifold gauge is between 2 - 5 in. Hg (1 O - 20 KPa).

21. Using a 6 mm hexagon socket wrench , remove
the overflow/drain plug and gasket.

Figure 5.

HINT
Place an oil drain pan under the transmission
overflow/drain plug to collect any transmission
fluid.

CAUTION
A small amount of HOT fluid may leak from the
overflow/drain plug port during removal.

NOTE
Ensure the sliding tube is fully retracted into the gauge housing before inserting into the
transmission inspection port.

HINT
The level/measurement indicator on the WS ATF Level Gauge will read 0 mm when the slid ing
tube is fully retracted.

NOTE
Before proceeding with the inspection, ensure the transmission fluid temperature is between
185° F -194° F (85°C - 90°C) and the engine idle speed is within the range specified in the
table above.

24 . Close the Fluid Extraction Tank upper valve by turning the handle perpendicular to the hose.
This will stop vacuum flow to the transmission and the vacuum gauge should read
0 in . Hg (0 KPa) .
25 . Observe transmission fluid leaking from the hose at the bottom of the WS ATF Level Gauge.

NOTE
• If fluid flows out slowly and only drips, then the transmission fluid level is within
specifications.
• If fluid flows out rapidly, allow excess fluid to drain to a slight drip.
• If no fluid flows out, add fluid using the Transmission Fill System until fluid begins to drip
(refer to " Fluid Level Adjustment Procedure" for instructions).

26 . Confirm fluid level is within specifications per steps 23 - 25 .
27 . Open the Fluid Extraction Tank upper valve by turning the handle in-line with the hose. This will
allow vacuum to be applied to the transmission and the vacuum gauge should read between
2 - 5 in . Hg (10 - 20 KPa) .

NOTE
Ensure vacuum is being applied to the transmission before proceeding to step 28.

28 . Remove the WS ATF Level Gauge.

Fluid Level Adjustment Procedure

Perform the following procedures if low fluid level is present using the WS ATF Level Gauge during
step 25.
NOTE
• Before adding transmission fluid, ensure the WS ATF Level Gauge is set to the correct level
according to the table in step 23.
• Ensure the transmission fluid temperature is between 185°F -194°F (85°C - 90° C) and the
engine idle speed is within the range specified in the table in step 23.
• Ensure both of the Transmission Fluid Extraction Tank valves are closed and no vacuum
is being applied to the transmission (Vacuum Regulator Manifold gauge should read
0 in. Hg [O KPa)).

1. Disconnect the Vacuum Regulator Manifold quick connect fitting from the Transmission
Fill Adapter.
2. Connect the Transmission Fill System quick connect fitting to the Transmission Fill Adapter.
SST: 00002-11100-02

3. Operate the manual pump slowly to add Toyota genuine WS transm ission flu id to
the transmission .
4. Observe for transmission fluid leaking from the hose at the base of the WS ATF Level Gauge.
NOTE
• If fluid flows out slowly and only drips, then the transmission fluid level is w ithin
specifications.
• If transmission fluid flows out rapidly, allow excess fluid to drain to a slight drip.
• If no transmission fluid flows out, continue adding fluid using the Transmission Fill
System until fluid begins to drip.

5. Confirm fluid level is within specifications per step 4.
6. After confirming fluid level is correct, disconnect the Transmission Fill System hose quick
·
connect from the Transmission Fill Adapter.
7. Reconnect the Vacuum Regulator Manifold hose quick connect to the Transmission Fill Adapter.
8. Open both of the Fluid Extraction Tank valves by turning the handle in-line with the hose to stop
additional fluid loss. This will allow vacuum to be applied to the transmission and the vacuum
gauge should read between 2 - 5 in . Hg (10 - 20 KPa) .
9. Remove the WS ATF Level Gauge.
10. Install the overflow plug with a new gasket.
Torque: 40 N*m (408 kgf*cm, 30 ft*lbf)
