Checking A/T Fluid

  1. Warm up engine.
  2. Check for A/T fluid leakage.
  3. Loosen the level gauge bolt.
  4. Before driving, A/T fluid level can be checked at A/T fluid temperatures of 30 to 50°C (86 to 122°F) using "COLD" range on A/T fluid level gauge as follows.
    1. Park vehicle on level surface and set parking brake.
    2. Start engine and move selector lever through each gear position. Leave selector lever in "P" position.
    3. Check A/T fluid level with engine idling.
    4. Remove A/T fluid level gauge and wipe clean with lint-free paper.
      CAUTION: When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.

    5. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
      CAUTION: To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T fluid charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
    6. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to the A/T fluid charging pipe.
      CAUTION: Do not overfill.
  5. Drive vehicle for approximately 5 minutes in urban areas.
  6. Make the A/T fluid temperature approximately 65°C (149°F).
    NOTE: A/T fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to perform operation while checking data with CONSULT-II.

    1. Connect CONSULT-II to data link connector. Refer to "CONSULT-II START PROCEDURE ".
    2. Select "MAIN SIGNALS" in "DATA MONITOR" mode for "A/T" with CONSULT-II.
    3. Read out the value of "ATF TEMP 1".
  7. Re-check A/T fluid level at A/T fluid temperatures of approximately 65°C (149°F) using "HOT" range on A/T fluid level gauge.
    CAUTION:
    • When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.
    • To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T fluid charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions as shown.
  8. Check A/T fluid condition.
    • If ATF is very dark or smells burned, check operation of A/T. Flush cooling system after repair of A/T.
    • If A/T fluid contains frictional material (clutches, bands, etc.), replace radiator and flush cooler line using cleaning solvent and compressed air after repair of A/T. Refer to "RADIATOR " (for VQ35DE engine), "RADIATOR " (for VK45DE engine) and "A/T FLUID COOLER CLEANING ".
  9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
