Inspection Procedure

1. Inspect fluid level at vehicle operating temperature.

   NOTE: This procedure references a Toyota vehicle 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. SST: 10002-00101-3

16. Attach the Vacuum Regulator Manifold quick connect fitting to the Transmission Fill Adapter. SST: 10002-00101-2

    Figure 3. Image showing the Vacuum Regulator Manifold quick connect fitting attached to the Transmission Fill Adapter.

17. Attach the Fluid Extraction Tank hose quick connect to the Vacuum Regulator Manifold. SST: 10002-00101-4

    Figure 4. Image showing the Fluid Extraction Tank hose quick connect attached to the Vacuum Regulator Manifold. Labels indicate 'Lower Valve' and 'Upper Valve'.

    1	Lower Valve
    2	Upper Valve

18. NOTE: Ensure both of the Fluid Extraction Tank valves are OFF by turning the valve handle perpendicular to the hose.

    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.

21. NOTE: Ensure the Vacuum Regulator Manifold gauge is between 2 – 5 in. Hg (10 – 20 KPa).

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

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

    Figure 5. Diagram showing the location of the transmission overflow/drain plug.

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

22. Install the WS ATF Level Gauge into the overflow/drain plug port using the 12 mm Adapter and hand-tighten the WS ATF Level Gauge until it is fully seated against the oil pan. SST: 10002-00101-1, SST: 10002-00101-6

    Figure 6. Image showing the WS ATF Level Gauge installed in the overflow/drain plug port, with a 12 mm adapter. The gauge has a sliding tube.

    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 sliding tube is fully retracted.

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:

    TRANSAXLE	ENGINE	DRIVE TYPE	VEHICLE		SPECIFIED MEASUREMENT AT FLUID TEMPERATURE OF 185°F – 194°F (85°C – 90°C)
    			MODEL	MODEL CODE	ENGINE IDLE SPEED 600 – 700 (RPM)	ENGINE IDLE SPEED 700 – 800 (RPM)
    U660E U660F	2GR-FE	FF	Avalon	GSX30	75.5 mm	72.0 mm
    			Camry	GSV40
    			Highlander	GSV50
    		4WD	Highlander	GSU50
    			Sienna	GSU55
    			Venza	GSL30
    		FF		GSL35
    		4WD		GGV10
    				GGV15
    U760E U760F	2AR-FE	FF	Camry	ASV40	71.0 mm	69.0 mm
    			RAV4	ASV50
    		4WD		ASA44
    		FF		ASA42
    	1AR-FE	FF	Highlander	ASU40	71.0 mm	69.0 mm
    			Sienna	ASU50
    			Venza	ASL30
    		4WD		AGV10
    				AGV15

    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 specification.
    • 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).

Fluid Level Adjustment Procedure

Perform the following procedures if low fluid level is present using the WS ATF Level Gauge during step 25.

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 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 specification.
   • 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)
