      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 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 CIRCULATION 
    1. Allow the engine to idle with the air conditioning OFF.
    2. Move the shift lever through entire gear range to circulate the fluid.
  5. CHECK FLUID TEMPERATURE 
    NOTE: The fluid temperature should be less than 30°C (86°F) before beginning the fluid temperature check.
    1. With the intelligent tester:
      1. Connect terminals CG (4) and TC (13) of the DLC3 using SST.

        SST 09843-18040 

      2. Move the shift lever back and forth between N and D every 1.5 second for 6 seconds.
      3. The D shift indicator on the combination meter comes on for 2 seconds. This indicates that the fluid temperature check mode has been started.

      4. Connect the intelligent tester to the DLC3.
      5. Select the tester menus: OBD/MOBD, ENGINE, DATA LIST and A/T.
      6. Check A/T OIL TEMP.
      7. Allow the engine to idle until the fluid temperature reaches 39°C (102°F).
    2. Without the intelligent tester (Using D shift indicator):
      1. Connect terminals CG (4) and TC (13) of the DLC3 using SST.

        SST 09843-18040 

      2. Move the shift lever back and forth between N and D every 1.5 second for 6 seconds.
      3. The D shift indicator on the combination meter comes on for 2 seconds. This indicates that the fluid temperature check mode has been started.
      4. The D shift indicator will come on again when the fluid temperature reaches 39°C (102°F) and will blink when it exceeds 49°C (120°F).
      5. Allow the engine to idle until the fluid temperature reaches 46°C (115°F).
  6. CHECK FLUID LEVEL 
    NOTE: The fluid temperature must be between 39°C (102°F) and 49°C (120°F) to accurately check the fluid level.
    1. Remove the overflow plug with the engine idling.
    2. Check that the fluid comes out of the overflow tube. If fluid does not come out, proceed to step 7. If fluid comes out, wait until the overflow slows to a trickle and proceed to step  8.
  7. REFILL TRANSMISSION WITH FLUID 
    1. Install the overflow plug.
    2. Stop the engine.
    3. Remove the refill plug.

    4. Add 0.4 liters (0.42 US qts, 0.35 lmp. qts) of fluid.
    5. Allow the engine to idle and wait for 10 seconds.
    6. Proceed to step  6.
  8. AFTER FILLING TRANSMISSION 
    1. Install the overflow plug with a new gasket.

      Torque: 20 N*m (204 kgf*cm, 15 ft.*lbf) 

    2. Stop the engine.
    3. Install the refill plug with a new O-ring.

      Torque: 39 N*m (400 kgf*cm, 29 ft.*lbf) 

    4. Install the transmission case cover with the 2 bolts.

      Torque: 5.4 N*m (55 kgf*cm, 48 in.*lbf)
