2004 Nissan-Datsun Sentra SE-RFACTORY OEM SERVICE PROCEDURE

Checking Fluid Levels

NOTE: The transmission fluid level cannot be read accurately, if the vehicle has been driven for an extended period at high speeds, or in city traffic in hot weather, or it is being used to pull a trailer. Wait about 30 minutes or until fluid has cooled down before checking fluid level.
  1. Warm up engine.
  2. Check for fluid leakage.
  3. Before driving, fluid level can be checked at fluid temperatures of 86-122°F (30-50°C) using COLD range on dipstick as follows:
    1. Park vehicle on level surface and set parking brake.
    2. Start engine and move gearshift lever through each gear position. Place gearshift lever in "P" position.
    3. Check fluid level with engine idling.
    4. Remove dipstick and note reading. If fluid level is at low side of either range, add fluid through fill pipe.
    5. Insert dipstick into fill pipe as far as it will go.
    6. Remove dipstick and note reading. If reading is at low side of range, add fluid through fill tube. See RECOMMENDED FLUIDS  . Do not overfill.
  4. Drive vehicle for about 5 minutes in urban areas.
  5. Re-check fluid level at fluid temperatures of 122-176°F (50-80°C) using HOT range on dipstick. Add fluid if necessary. See RECOMMENDED FLUIDS  .
  6. Check fluid condition. If fluid is very dark or smells burned, See appropriate DIAGNOSIS article. Flush cooling system after repair of transaxle. If transmission fluid contains frictional material (clutches, bands, etc.), replace radiator and flush cooler line using cleaning solvent and compressed air after repair of transaxle.
