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 (10 — 20 KPa).

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. 4

Adjust the WS ATF Level Gauge to the correct measurement according to the table below and
lock the sliding scale by securing the thumb screw:

oan SPECIFIED MEASUREMENT AT FLUID
DRIVE TEMPERATURE OF 185°F - 194°F (65°C - 90°C)

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.

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).

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).

Confirm fluid level is within specifications per steps 23 — 25.

Open the Fiuid 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
2-5in. Hg (10 - 20 KPa).

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

Remove the WS ATF Level Gauge.

WS ATF Level Adjustment for U660E/F Transmissions

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
[0 KPa).

. Disconnect the Vacuum Regulator Manifold quick connect fitting from the Transmission Fill

Adapter.

. Connect the Transmission Fill System quick connect fitting to the Transmission Fill Adapter.

SST: PIN 00002-11100-02

. Operate the manual pump slowly to add Toyota genuine WS transmission fluid to the

transmission.

. 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 within
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.

. Confirm fluid level is within specifications per step 4.

. After confirming fluid level is correct, disconnect the Transmission Fill System hose quick

connect from the Transmission Fill Adapter.

. Re-Connect the Vacuum Regulator Manifold hose quick connect to the Transmission Fill Adapter.

. 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).

. Remove the WS ATF Level Gauge.
