Checking A/T Fluid

WARNING: This page is about a different car, the 2005 Infiniti FX45 and 2005 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
  1. Warm up engine.
  2. Check for fluid leakage.
  3. Remove the tightening bolt for ATF level gauge.
  4. Before driving, fluid level can be checked at fluid temperatures of 30 to 50°C (86 to 122°F) using "COLD" range on ATF 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 fluid level with engine idling.
    4. Remove ATF level gauge and wipe clean with lint-free paper.
      CAUTION: When wiping away the fluid level gauge, always use lint-free paper, not a cloth one.
    5. Re-insert ATF level gauge into charging pipe as far as it will go.
      CAUTION: To check fluid level, insert the ATF level gauge until the cap contacts the end of the charging pipe, with the gauge reversed from the normal attachment conditions.
    6. Remove ATF level gauge and note reading. If reading is at low side of range, add fluid to the charging pipe.
      CAUTION: Do not overfill.
  5. Drive vehicle for approximately 5 minutes in urban areas.
  6. Make the fluid temperature approximately 65°C (149°F).
    NOTE: 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.
    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 fluid level at fluid temperatures of approximately 65°C (149°F) using "HOT" range on A/T fluid level gauge.
    CAUTION:
    • When wiping away the fluid level gauge, always use lint-free paper, not a cloth one.
    • To check fluid level, insert the ATF level gauge until the cap contacts the end of the charging pipe, with the gauge reversed from the normal attachment conditions as shown.
  8. Check fluid condition.
    • If fluid is very dark or smells burned, check operation of A/T. Flush cooling system after repair of A/T.
    • If ATF 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 ", "RADIATOR ".
