A750E AUTOMATIC TRANSMISSION FLUID: ADJUSTMENT
ADJUSTMENT
1. BEFORE FILLING TRANSMISSION
- This transmission requires Toyota Genuine ATF WS transmission fluid.
- After servicing the transmission, you must refill the transmission with the correct amount of fluid.
- Maintain the vehicle in a horizontal position while adjusting the fluid level.
- Proceed to the "Transmission Pan Fill" procedures if you replaced the entire transmission, transmission pan, drain plug, valve body and/or torque converter.
- Proceed to the "Transmission Fill" procedures after removing the refill plug if you replaced the transmission hose and/or output shaft oil seal.
2. TRANSMISSION PAN FILL
(a) Remove the refill plug and overflow plug.
(b) Fill the transmission through the refill hole until fluid begins to trickle out of the overflow tube.
(c) Reinstall the overflow plug.
3. TRANSMISSION FILL
(a) w/ Trailer Towing System (w/ Thermostat):
Push the shaft of the thermostat and fix it in place.
(1) By using compressed air, etc., blow dust off of the thermostat's cap to clean it.
(2) Using a screwdriver, push the shaft of the thermostat.
HINT: Pushed amount: 5.5 to 7.0 mm (0.217 to 0.276 in.)
(3) With the shaft of the thermostat pressed, push a pin (diameter: 1.0 to 1.8 mm (0.0394 to 0.0709 in.)) into a hole on the side of the thermostat's cap. Insert the pin until it pierces through the hole on the other side of the thermostat's cap to fix the shaft in place.
(b) Fill the transmission with the amount of fluid listed in the table below.
Standard capacity:
(c) Reinstall the refill plug to prevent the fluid from splashing.
HINT: If you cannot add the listed amount of fluid, do the following:
(1) Install the refill plug.
(2) Allow the engine to idle with the air conditioning OFF.
(3) Move the shift lever through the entire gear range to circulate fluid.
(4) Wait for 30 seconds with the engine idling.
(5) Stop the engine.
(6) Remove the refill plug and add fluid.
(7) Reinstall the refill plug.
4. FLUID TEMPERATURE CHECK
NOTE: The fluid temperature can be confirmed by checking the indicator light in the meter or by using the Techstream. When using the Techstream, it is necessary to change to temperature detection mode in order to idle the vehicle appropriately.
(a) When using the Techstream:
(1) Turn the ignition switch OFF.
(2) Connect the Techstream to the DLC3.
(3) Turn the ignition switch ON.
(4) Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1.
(5) Enter the following menus: Powertrain / ECT / Data List / A/T Oil Temperature 1.
(6) Check ATF temperature.
NOTICE:
- The ATF temperature must be between 36 to 46°C (97 to 115°F).
- If the ATF temperature is not between 36 to 46°C (97 to 115°F), turn the ignition switch off and wait until the fluid temperature drops between 36 to 46°C (97 to 115°F).
(7) According to the display on the Techstream, perform the Active Test "Connect the TC and TE1".
HINT: Indicator lights of the combination meter blink to output DTCs when TC and TE1 are connected.
(8) Start the engine.
NOTE: Check that electrical systems such as the air conditioning system, audio system and lighting system are off.
(b) When not using the Techstream (using indicator light):
(1) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
SST: 09843-18040
(2) Start the engine.
NOTE: Check that electrical systems such as the air conditioning system, audio system and lighting system are off.
HINT: Indicator lights of the meter blink to output DTCs when terminals TC and CG are connected.
(c) Slowly move the shift lever from P to S, then change the gears from 1st to 6th. 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 (D) remains illuminated for 2 seconds and then turns off.
(e) When using the Techstream:
(1) Return the shift lever to P and press OFF on the Active Test display.
(f) When not using the Techstream:
(1) Return the shift lever to P and disconnect terminals 13 (TC) and 4 (CG).
(g) Allow the engine to idle until the fluid temperature reaches 36 to 46°C (97 to 115°F).
(h) The indicator (D) will come on again when the fluid temperature reaches 36°C (97°F) and will blink when it exceeds 46°C (115°F).
Indicator Indication of ATF Temperature:
NOTE: Perform the fluid level inspection while the indicator light is on.
5. FLUID LEVEL CHECK
NOTE: The fluid temperature must be between 36° (97°F) and 46°C (115°F) to accurately check the fluid level.
(a) Remove the overflow plug with the engine idling.
(b) Check that the fluid comes out of the overflow tube.
If fluid does not come out, proceed to the "Transmission Refill" procedures.
If fluid comes out, wait until the overflow slows to a trickle and proceed to the "Complete" procedures.
6. TRANSMISSION REFILL
(a) Remove the overflow plug.
(b) Remove the refill plug.
(c) Add ATF into the refill hole until ATF flows from the overflow tube.
(d) Wait until the overflow slows to a trickle and proceed to the "Complete" procedures.
7. COMPLETE
(a) Install a new gasket and the overflow plug.
Torque: 20 Nm (204 kgf-cm, 15 ft-lbf)
(b) Stop the engine.
(c) Install a new gasket and the refill plug.
Torque: 39 Nm (400 kgf-cm, 29 ft-lbf)
(d) w/ Trailer Towing System (w/ Thermostat):
(1) Remove the pin.
NOTICE:
- Make sure the shaft of the thermostat is protruding from the hole of the cap.
- Check that there is no ATF leaking from the cap hole.
