Procedures
A750E AUTOMATIC TRANSMISSION: 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. 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.
2. 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.
Standard capacity:
(e) Install the refill plug.
HINT
If you cannot fill the listed amount of fluid, do the following below:
(1) Start the engine to idle.
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.
3. FLUID TEMPERATURE CHECK
NOTICE:
The ATF temperature can be confirmed by using a Techstream.
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch ON.
(d) Enter the following menus: Powertrain / Engine and ECT / Data List / A/T Oil Temperature 1.
(e) Check the ATF temperature.
NOTICE:
If the ATF temperature is above 46°C (115°F), turn the ignition switch off and wait until the fluid temperature drops to between 36 and 46°C (97 and 115°F).
4. 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 36 and 46°C (97 and 115°F) to accurately check the fluid level.
(a) Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1.
Standard condition:
Indicator lights on the combination meter blink.
HINT
When not using the Techstream: using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

SST : 09843-18040
(b) Start the engine to idle.
NOTICE:
Check that electrical systems such as the air conditioning system, audio system and lighting system are off.
(c) Slowly move the shift lever from P to L, and then return the shift lever to P.
HINT
Slowly move the shift lever to circulate the fluid through each part of the transmission.
(d) Move the shift lever to D, and quickly move 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 [A/T OIL TEMP] remains on for 2 seconds and then turns off.
(e) Return the shift lever to P and terminate the Active Test on the Techstream.
(f) Using the Techstream, allow the engine to idle until the fluid temperature reaches 36 to 46°C (97 to 115°F).
HINT
The indicator [A/T OIL TEMP] will come on again when the fluid temperature reaches 36°C (97°F) and will blink if it exceeds 46°C (115°F).
Indicator [A/T OIL TEMP] Indication of ATF Temperature
NOTICE:
When checking the fluid temperature using the indicator light, make sure that the shift lever is in P.
(g) Remove the overflow plug with the engine idling.

(h) Wait until the overflow slows to a trickle.
NOTICE:
If the fluid does not overflow, do the following below:
(1) Remove the refill plug.
(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.
(i) Install a new gasket and the overflow plug.
Torque : 20 Nm (204 kgf-cm, 15 ft-lbf)
(j) Install a new gasket and the refill plug.
Torque : 39 Nm (400 kgf-cm, 29 ft-lbf)
5. COMPLETE
(a) Turn the ignition switch off.
(b) Disconnect the Techstream from the DLC3.
(c) Inspect for automatic transmission fluid leak.
