Fluid - A/T: Service and Repair
A760F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION FLUID: ADJUSTMENT
NOTICE:
* This transmission requires Toyota Genuine ATF WS.
* After servicing the transmission, you must follow the ATF adjustment procedure.
* Maintain the vehicle in a horizontal position while adjusting the fluid level.
1. PRELIMINARY PROCEDURES
(a) w/ Rear Air Suspension System:
When jacking up or lifting the vehicle, stop operation of the air suspension control system by pressing the height control mode select switch.
(b) Using compressed air, etc., blow dust off the thermostat cap to clean it.
(c) Using a screwdriver, push in the shaft of the thermostat.
HINT
* Distance pushed: 5.5 to 7.0 mm (0.217 to 0.276 in.)
* Push in the shaft until the screwdriver contacts the step inside the cap.
(d) With the shaft of the thermostat pressed in, push a pin into a hole in the side of the thermostat cap. Insert the pin until it passes through the hole in the other side of the thermostat cap to fix the shaft in place.

HINT
Pin diameter: 1.0 to 1.8 mm (0.0394 to 0.0709 in.)
2. BEFORE FILLING TRANSMISSION
When you have replaced the entire transmission, transmission pan, drain plug, valve body and/or torque converter, proceed to the "Transmission Fill" procedures.
When you have replaced the transmission hose and/or output shaft oil seal, proceed to the "Fluid Temperature Check" procedures.
3. TRANSMISSION FILL
(a) Remove the refill plug and overflow plug.

(c) Reinstall the overflow plug.
(d) Fill the transmission with the amount of fluid listed in the table below.
Reference Capacity:
(e) Install the refill plug.
HINT
If you cannot fill the listed amount of fluid, perform the following:
(1) Start the engine and idle it.
NOTICE:
Check that electrical systems such as the air conditioning system, audio system and lighting system are off.
(2) Move the shift lever through the entire gear range to circulate the fluid.
(3) Wait for 30 seconds with the engine idling.
(4) Stop the engine.
(5) Remove the refill plug.
(6) Fill the transmission with the remaining fluid until the amount in the table has been filled.
(7) Install the refill plug.
4. FLUID TEMPERATURE CHECK
NOTICE:
The ATF temperature can be confirmed by using the Techstream.
(a) Turn the engine switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the engine switch on (IG).
(d) Enter the following menus: Powertrain / ECT / Data List / A/T Oil Temperature 1.
(e) Check the ATF temperature.
NOTICE:
If the ATF temperature is higher than 46°C (115°F), turn the engine switch off and wait until the fluid temperature drops to below 46°C (115°F).
5. FLUID LEVEL CHECK
NOTICE:
* It is necessary to change to temperature detection mode in order to idle the vehicle appropriately.
* The ATF temperature must be between 46 and 52°C (115 and 126°F) to accurately check the fluid level.
(a) When using the Techstream:
Enter the following menus: Powertrain / ECT / Active Test / Connect the TC and TE1.
Standard condition:
Indicator lights in the combination meter blink.
(b) When not using the Techstream:
Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
SST : 09843-18040
Standard condition:
Indicator lights in the combination meter blink.

(c) Start the engine and idle it.
NOTICE:
Check that electrical systems such as the air conditioning system, audio system and lighting system are off.
(d) Slowly move the shift lever from P to S, and then change the gear from 1st to 5th. Then return the shift lever to P.
HINT
Slowly move the shift lever to circulate the fluid through each part of the transmission.
(e) Move the shift lever to D, and quickly move it back and forth between N and D (once within 1.5 seconds) for at least 6 seconds. This will activate the fluid temperature detection mode.
Standard condition:
Indicator light [D] remains illuminated for 2 seconds and then turns off.
(f) When using the Techstream:
Return the shift lever to P and terminate the Active Test on the Techstream.
(g) When not using the Techstream:
Disconnect SST from the DLC3.
(h) Allow the engine to idle until the fluid temperature reaches 46 to 52°C (115 to 126°F).
HINT
The indicator [D] will come on again when the fluid temperature reaches 46°C (115°F) and will blink if it is higher than 52°C (126°F).
Indicator [D] Indication of ATF Temperature
(i) Remove the overflow plug and gasket with the engine idling.
Text in Illustration
(j) Wait until the overflow slows to a trickle.
NOTICE:
If the fluid does not overflow, perform the following:
(1) Remove the refill plug and gasket.
(2) Refill the transmission through the refill hole until fluid begins to trickle out of the overflow tube.
(3) Wait until the overflow slows to a trickle.
(4) Install a new gasket and the refill plug.
Torque : 39 Nm (400 kgf-cm, 29 ft-lbf)
(k) Install a new gasket and the overflow plug.
Torque : 20 Nm (204 kgf-cm, 15 ft-lbf)
6. COMPLETE
(a) Turn the engine switch off.
(b) When using the Techstream:
Disconnect the Techstream from the DLC3.
(c) Push in the shaft with a screwdriver and remove the pin.

NOTICE:
Make sure the shaft of the thermostat is protruding from the hole in the cap.
(d) Inspect for automatic transmission fluid leaks.
