Required Tools & Equipment
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 / ECT / 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.
12. Lift the vehicle.
NOTE
Set the vehicle on a lift so that the vehicle is kept level (make sure the tilt angle from the front to rear and side to side of the vehicle is
within +/- 1°)
13. Remove the 2 bolts clip and front fender apron seal LH.
14. Remove the refill plug and gasket.
15. Install the Transmission Fill Adapter into the transmission fill port.

16. Attach the Vacuum Regulator Manifold quick connect fitting to the Transmission Fill Adapter.
SST: P/N 10002-00101-2
17. Attach the Fluid Extraction Tank hose quick connect to the Vacuum Regulator Manifold.
SST: P/N 10002-001014
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 Tool Tank.
CAUTION
Do NOT exceed 100 psi of shop air pressure to the Fluid Extraction Tool 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 (10 - 20 KPa).

21. Using a 6 mm hexagon socket wrench remove the overflow/drain plug and gasket.
22. Install the WS ATF Level Gauge into the overflow/drain plug port using the 12 mm Adapter and ensure the WS ATF Level Gauge is fully
seated against the oil pan.

23. 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:
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.
^ 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.
29. Install the overflow/drain plug with a new gasket.
Torque: 40 N*m (408 kgf*cm, 36 ft*lbf)
30. 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).
31. Close the Fluid Extraction Tank LOWER valve by turning the handle perpendicular to the hose.
32. Disconnect the shop air hose from the Fluid Extraction Tank.
33. Disconnect the Fluid Extraction Tank hose quick connect from the Vacuum Regulator Manifold.
34. Disconnect the Vacuum Regulator Manifold quick connect from the Transmission Fill Adapter.
35. Remove the Transmission Fill Adapter from the transmission fill port.
36. Install the refill plug with a new gasket.
Torque: 40 N*m (408 kgf*cm, 36 ft*lbf)
37. Check for fluid leaks.
38. Clean any remaining oil residue from the transmission case/oil pan.
39. Install the front fender apron seal LH with the 2 bolts and clip.

40. Lower the vehicle.
41. Remove Techstream from the DLC3.
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]).
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: P/N 00002-11100-02
3. Operate the manual pump slowly to add Toyota genuine WS transmission fluid 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 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.
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. Re-Connect 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, 36 ft*lbf)
11. Close the Fluid Extraction Tank UPPER valve by turning the handle perpendicular to the hose.
12. Close the Fluid Extraction Tank LOWER valve by turning the handle perpendicular to the hose.
13. Disconnect the shop air hose from the Fluid Extraction Tank.
14. Disconnect the Fluid Extraction Tank from the Vacuum Regulator Manifold.
