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.

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.

  • If the amount of automatic transmission fluid that comes out of the overflow hole is large, proceed to step [*1].
  • If no automatic transmission fluid comes out of the overflow hole, proceed to step [*2].

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]
