ADJUSTMENT

PROCEDURE

1. BEFORE FILLING TRANSMISSION

2. FILL TRANSMISSION PAN WITH FLUID

(a) Lift the vehicle.

NOTICE:

Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure that the tilt angle from the front to rear of the vehicle is within +/-1°).

(b) Remove the refill plug and O-ring from the automatic transmission assembly.

(c) Using a 5 mm hexagon socket wrench, remove the overflow plug and gasket from the automatic transmission assembly.

(d) Add automatic transmission fluid to the refill hole until it flows out of the overflow hole. Text in Illustration *a Refill Hole *b Overflow Hole NOTICE: Use Toyota Genuine ATF WS. Be sure to add automatic transmission fluid slowly. If automatic transmission fluid is added quickly, the automatic transmission fluid may hit internal parts and bounce back, resulting in automatic transmission fluid coming out of the refill hole.

(e) Wait until the automatic transmission fluid flow slows and only drips come out.

(f) Using a 5 mm hexagon socket wrench, temporarily install the overflow plug and gasket to the automatic transmission assembly. HINT: Reuse the old gasket as the overflow plug will be removed again.

3. FILL TRANSMISSION

4. CHECK FLUID TEMPERATURE

NOTICE:

The automatic transmission fluid temperature can be confirmed by checking the D shift indicator on the combination meter or using the Techstream. When not using the Techstream, it is necessary to enter automatic transmission fluid temperature detection mode.

(a) When using the Techstream:

HINT:

The actual ATF temperature can be checked on the Data List using the Techstream.

(1) Connect the Techstream to the DLC3 with the ignition switch off.

(2) Turn the ignition switch to ON and turn the Techstream on.

NOTICE:

To reduce load, make sure that all electrical systems, such as the air conditioning, lighting system, electric fan and audio system are off.

(3) for 2GR-FKS:

(4) for 2TR-FE:

(5) Select the Active Test item: Connect the TC and TE1 / ON.

(6) Select the Data List menu: A/T Oil Temperature 1.

(7) Check the ATF temperature.

(8) Depress and hold the brake pedal.

(9) Start the engine.

To reduce load, make sure that all electrical systems, such as the air conditioning, lighting system, electric fan and audio system, are off.

(10) Slowly move the shift lever from P to S, then move the shift lever to P.

HINT:

Slowly move the shift lever to circulate the automatic transmission fluid through each part of the automatic transmission assembly.

(11) While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of less than 1.5 seconds for 6 seconds or more.

NOTICE:

Do not pause for more than 1.5 seconds.

HINT:

Performing this operation will cause the vehicle to enter automatic transmission fluid temperature detection mode.

(12) Check that the D shift indicator comes on for 2 seconds. HINT: When fluid temperature detection mode is activated, the D shift indicator on the combination meter comes on for 2 seconds. If the D shift indicator does not come on for 2 seconds, return to the first step and perform the procedure again.

(13) Move the shift lever from N to P.

(14) Release the brake pedal.

(15) Select the Active Test item: Connect the TC and TE1 / OFF.

NOTICE:

Be sure that terminals TC and TE1 are not connected. If the terminals are connected, the fluid level cannot be precisely adjusted due to fluctuations in engine speed.

(b) When not using the Techstream:

(1) Connect terminals CG (4) and TC (13) of the DLC3 using SST. Text in Illustration *a DLC3 SST: 09843-18040

(2) Depress and hold the brake pedal.

(3) Start the engine.

NOTICE:

To reduce load, make sure that all electrical systems, such as the air conditioning, lighting system, electric fans and audio system, are off.

HINT:

The indicator lights on the combination meter blink to indicate DTCs when terminals TC and CG are connected.

(4) Slowly move the shift lever from P to S, then move the shift lever to P.

HINT:

Slowly move the shift lever to circulate the automatic transmission fluid through each part of the automatic transmission assembly.

(5) While observing the D shift indicator on the combination meter, move the shift lever back and forth between N and D at an interval of less than 1.5 seconds for 6 seconds or more.

NOTICE:

Do not pause for more than 1.5 seconds.

HINT:

Performing this operation will cause the vehicle to enter automatic transmission fluid temperature detection mode.

(6) Check that the D shift indicator comes on for 2 seconds. HINT: When fluid temperature detection mode is activated, the D shift indicator on the combination meter comes on for 2 seconds. If the D shift indicator does not come on for 2 seconds, return to the first step and perform the procedure again.

(7) Move the shift lever from N to P.

(8) Release the brake pedal.

(9) Remove SST from terminals 13 (TC) and 4 (CG). Text in Illustration *a DLC3 SST: 09843-18040 NOTICE: Be sure that terminals TC and CG are not connected. If the terminals are connected, the automatic transmission fluid level cannot be precisely adjusted due to fluctuations in engine speed. HINT: Disconnecting terminals TC and CG activates the engine idle speed control mode. Even after terminals TC and CG are disconnected, automatic transmission fluid temperature detection mode will be active until the ignition switch is turned off.

(c) Allow the engine to idle until the automatic transmission fluid temperature reaches 35 to 45°C (95 to 113°F).

(d) The D shift indicator will come on again when the fluid temperature reaches 35°C (95°F) and will blink when it exceeds 45°C (113°F).

HINT:

5. CHECK FLUID LEVEL

(a) Lift the vehicle.

NOTICE:

Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure that the tilt angle from the front to rear of the vehicle is within +/-1°).

(b) Using a 5 mm hexagon socket wrench, remove the overflow plug and gasket from the automatic transmission assembly. CAUTION: Be careful as the automatic transmission fluid coming out of the overflow hole is hot.

(c) Check the amount of automatic transmission fluid that comes out of the overflow hole.

NOTICE:

If only a small amount of automatic transmission fluid (approximately 5 cc) comes out of the overflow hole, then only automatic transmission fluid remaining in the overflow tube of overflow hole has come out. This is not considered to be overflow.

(d) If the amount of automatic transmission fluid that comes out of the overflow hole is large, wait until the automatic transmission fluid flow slows and only drips come out. [*1] HINT: The automatic transmission fluid flow will not stop completely because the automatic transmission fluid continues to expand as its temperature increases.

(e) If no automatic transmission fluid comes out of the overflow hole, remove the refill plug and O-ring. Then add automatic transmission fluid to the refill hole until it flows out of the overflow hole. Wait until the automatic transmission fluid flow slows and only drips come out. [*2] Text in Illustration *a Refill Hole *b Overflow Hole NOTICE: Use Toyota Genuine ATF WS. Be sure to add automatic transmission fluid slowly. If automatic transmission fluid is added quickly, the automatic transmission fluid may hit internal parts and bounce back, resulting in automatic transmission fluid coming out of the refill hole.

(f) Wait until the automatic transmission fluid flow slows and only drips come out. HINT: The automatic transmission fluid flow will not stop completely because the automatic transmission fluid continues to expand as its temperature increases.

(g) Using a 5 mm hexagon socket wrench, install a new gasket and the overflow plug to the automatic transmission assembly. Torque: 20 N·m {204 kgf·cm, 15 ft·lbf}
